21/08/15: Understanding Melting Temperature (Tm)

August 21, 2015 by · Leave a Comment 

TM_IDTHybridization is a common step of many, if not most, molecular biology protocols. For example: northern and Southern analysis, PCR/qPCR, cloning, in situ hybridization, array analysis, gene knockdown, and next generation sequencing (NGS).

The criteria for hybridization are based on nucleic acid strand melting. Therefore, an understanding of melting temperature (Tm) provides information on when and how the DNA or RNA strands are going to hybridize and defines the rules for hybridization. It is very important to understand this process so that you can better design and optimize the oligos for your experiments.

This is why Integrated DNA Technologies have put together this nice article so that you can understand Tm better and hopefully design better oligonucleotide based experiments.

This is probably a good time to mention IDT’s useful OligoAnalyzer online tool.

14/08/15: Generate Consistent, Reliable Exome Sequencing Results

August 14, 2015 by · Leave a Comment 

A short article from Integrated DNA Technologies (IDT), about their exome targeted sequencing panel.

In my mind there is no better manufacturer of DNA oligos than IDT. Synthesizing many thousands of capture oligos (and biotinylating them) seems like an insane task, but IDT have done it. And what is the result? Now you can obtain deep and uniform coverage of the coding regions for 19,396 genes, minimizing the need for further analysis. Spanning 39 Mb of the human genome, the xGen® Exome Research Panel I is compatible with common sequencing platforms.

13/08/15: More gBlocks® Gene Fragments for your money…

August 13, 2015 by · Leave a Comment 

gBlocks ApplicationsI love IDT’s gBlocks and I think it’s fair to say that many of IDT’s customers like them – at least based on my experience here in Denmark. The best compliment they’ve been paid is imitation from at least one, rather large company in the same field.

Apart from being a true innovation in the synthetic biology field (and yes, I do realize that the word “innovative” is massively over-used in life science marketing), gBlocks greatly reduced (more or less halved) the cost of ordering genes, but in addition IDT still keep improving this product line. Hence the subject of this posting.

So basically, IDT have kept the cost of gBlocks the same, but increased the amount of product you receive. Details below.

 

11/08/15: qPCR Terminology – What Does It Mean?

August 12, 2015 by · Leave a Comment 

amplifying DNAAlthough qPCR seems to have been around for ever, I realize that not everyone is as familiar with it as I am. It’s often easy for me to assume, when talking to my customers, that they are familiar with the terms most commonly associated with using qPCR. While I’m no expert in the use of qPCR, I’ve been involved with it in some way (i.e., on the product sales and marketing side) for close to 15 years. So, it’s easy to forget that, for some people who are just getting started in research, this stuff is mostly new to them.

Here, I’m bringing your attention to a recent DECODED article from Integrated DNA Technologies (IDT) called

qPCR Terminology – What Does It Mean?

I particularly recommend newbies to check out the links at the end of the article to the MIQE Guidelines and IDT’s very own qPCR Application Guide.

20/06/13: Single Cell Expression Profiling—Breaking Down Biological Complexity – A Webinar

June 21, 2013 by · Leave a Comment 

Single Cell for qPCRIDT have arranged a webinar with the very knowledgeable (and nice) Professor Mikael Kubista, on the subject of doing single-cell expression profiling. This is a subject that I see being of increasing interest to researchers. Perhaps it may also have future application in the fertility field, so the techniques here might end up in a clinical setting one day. Who knows?

Professor Mikael Kubista and colleagues pioneered “single-cell expression profiling” by qPCR. They have observed surprisingly large variation in the numbers of transcripts found among cells collected from seemingly homogenous tissues and even among like cells in culture. Distinct gene expression patterns can be used to distinguish cell types, subtypes, and subpopulations.

In this webinar, Kubista will describe the workflow his group uses for single-cell expression profiling and their research monitoring the activation of astrocytes in response to brain trauma in mice, stressing important experimental design aspects. He will also present intracellular expression profiling and multianalyte single-cell profiling, demonstrating the simultaneous measurements of DNA, mRNA, microRNA, lncRNA, and protein in the same cell.

There are going to be two webinar sessions. The choice of which one to go for will most likely come down to your own time zone.

Session 1:
Tuesday, June 25th
7:00am CDT / 2:00pm CEST / 8:00pm SGT

30/05/13: Cool! IDT Now Offer qPCR Assay Plates

May 30, 2013 by · Leave a Comment 

bigstock-PCR-multiwell-plate-40743283

I think that this is a great new release by Integrated DNA Technologies (IDT, www.idtdna.com).

It’s been a long-awaited release. IDT has announced the launch of PrimeTime® qPCR Assay Plates, for high throughput qPCR analysis. Primers and probes for 5’-nuclease and intercalating dye assays (e.g., SYBR®) can now be directly ordered online in a 96 well plate format, eliminating the time-consuming transfer of primers and probes from reagent stocks, and streamlining the reaction set-up. PrimeTime qPCR Assay Plates offer an ideal solution for many applications that generate large quantities of data, such as validation of NGS and microarray data, as well as high throughput gene expression screening.

Addressing the needs of each particular qPCR assay requirement, a range of primer and/or probe concentrations are available, delivered lyophilized within a 96 deep-well plate. For additional flexibility, different dye-quencher combinations can also be ordered on the same plate, extending the range of assays that can be performed during a single run. The researcher does not even need to purchase a complete 96 well plate, just 24 assays is the minimum per plate order. Further cost savings are possible once a plate layout has been designed, since replicate plates can be generated at a lower total cost per reaction, making this format particularly suited to high throughput applications in academia and industry.

Designing and ordering your custom assays in this new plate format is rapid and intuitive with the online PrimeTime® qPCR assay tool, which allows users to easily create a master plate via simple copy and paste actions from source data. Alternatively, researchers can select from a specialized library of predesigned human, mouse, or rat assays generated by IDT’s sophisticated design engine. In addition to incorporating accurate Tm and secondary structure prediction data, this assay design engine takes into account the latest data from the NCBI RefSeq database, to avoid off- target amplification and SNPs, thus ensuring maximum assay performance.

As standard, IDT ensures the highest quality oligonucleotide synthesis, with full QC assessment by mass spectrometry, and results available free of charge on our website.

11/03/13: Awesome News for Synthetic Biologists from IDT

March 11, 2013 by · Leave a Comment 

Gene synthesis performed by a miniature woman, the hard way!

Below is the text from a recent joint press release from IDT and SGI-DNA.

The awesome bit is that soon, synthetic DNA constructs up to 2 Mbp will be available from IDT. I might be wrong, but that is a huge leap in the potential size of synthetic genes.

CORALVILLE, IA AND LA JOLLA, CA (February 27, 2013). Integrated DNA Technologies, Inc. (IDT) and SGI-DNA announce an expanded partnership to develop, manufacture, and market a variety of synthetic DNA products. 

IDT is the world’s leader in custom oligonucleotide synthesis and SGI-DNA is a newly formed subsidiary of Synthetic Genomics, Inc. (SGI), which focuses on  genomic-driven solutions to a variety of global needs.

In February of 2012, IDT and SGI began to co-manufacture, commercialize, and market small synthetic gene products of up to 5 kb. IDT also launched its gBlocks™ Gene Fragments product line, for use in combination with SGI’s proprietary DNA technologies, including Gibson Assembly™, to assemble small gene constructs efficiently. gBlocks™ Gene Fragments have already revolutionized synthetic biology applications by substantially lowering DNA synthesis costs and making DNA assembly more efficient and reliable.

IDT and SGI-DNA are now extending this collaboration to manufacture and co-brand cloned synthetic DNA constructs up to 2 Mbp, and to make them available through IDT. This product offering has not been available until today and will make possible new applications including metabolic and whole genome engineering through de novo DNA synthesis. SGI-DNA will manufacture and become IDT’s exclusive supplier of the larger constructs. The two companies will also work together on the launch of an expanded IDT gBlocks Gene Fragments offering, expected later in 2013.

Dr. Joseph Walder, IDT’s Founder and Chief Executive Officer, noted, “By joining forces, IDT and SGI-DNA will enable the research community by providing a complete solution, from short genes to very large synthetic constructs, at prices and with delivery times simply unavailable in the market today.” “Enabling new and better research has always been the essence of IDT’s mission, so it’s the perfect fit.”

“Over the last year, we have grown our in-house gene synthesis business, and effectively worked together with IDT to co-manufacture and co-market smaller synthetic gene products. This is the natural next step in that collaboration,” agreed J. Craig Venter, Ph.D., SGI’s Founder and Chief Executive Officer. He continued, “We are excited about what we’ll accomplish through the combination of SGI-DNA’s unique expertise with large, complex gene products and IDT’s experience in manufacturing and delivering small DNA products to researchers around the globe.”

SGI is also announcing the official launch of SGI-DNA, which will be responsible for all aspects of the development, manufacture, and commercialization of SGI’s synthetic DNA business.

IDT and SGI-DNA did not disclose the financial details of their arrangement.
