CRISPR webinar: New RNA tools for optimized CRISPR/Cas9 genome editing

Gene Editing CRISPR1600, October 7, 2015 (Denmark time)

Program overview

The CRISPR/Cas9 system has emerged as one of the leading tools for modifying the genomes of organisms ranging from E. coli to humans. In this webinar, we will discuss various methods for generating the crRNA and tracrRNA components that are required for guiding the Cas9 endonuclease to genomic targets. You will also learn how to optimize a new 2-part CRISPR RNA system from IDT that offers multiple benefits over other technologies.

28/09/15: Increase sensitivity and precision in your qPCR experiments

September 28, 2015 by · Leave a Comment 

ZEN™ and TAO™ Double-Quenched Probes improve qPCR data

A lot of researchers I speak to are unaware that Integrated DNA Technologies (IDT, www.idtdna.com) are able to sell probe-based qPCR assays, providing them fast, at a great price and allowing researchers to see the sequences of their primer:probe combinations. Even fewer are unaware that IDT has actually made some innovation to the standard quencher-dye configuration of qPCR probes.

In this article from DECODED, you can get a little bit more information about IDT’s ZEN™ and TAO™ double-quenched probes and why they can really help your experiments by improving your qPCR data.

18/09/15: Running Agarose and Polyacrylamide Gels

September 18, 2015 by · Leave a Comment 

We’ve all had to at some time or another

Do you reckon you could teach a newbie the most important tips for running gels, from the top of your head right now? Sure, you know how to run gels, but if you were teaching best practice, do you think you could do it?

Why not check your memory and lab knowledge by reading this article from Integrated DNA Technologies and seeing if you are still a gel-master.

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.

  • Detect base-substitution and insertion/deletion mismatches
  • Identify mutations in DNA fragments up to 3.5 kb in a single reaction
  • Quickly determine the number of mutations from the number of cleavage products
  • Detect rare variant alleles (as few as 1 in 32) in pooled samples
  • Use with various analysis platforms

140625 Data Overload

This particular subject (NGS metrics) has always been a head-scratcher for me, even though I shamefacedly admit that I am supposed to know this stuff, having been involved in targeted sequencing enrichment for over 6 years. So, I’m pleased that Ibrahim Jivanjee from Integrated DNA Technologies has put together a nice article to explain the most important terms used in the targeted sequencing field. I already feel better knowing I can go back to this article when I start to forget…

qPCR Curves IDT

As you’d expect from the world’s leading manufacturer of oligonucleotides, IDT have accumulated a lot of knowledge about qPCR. You might think it is easy to just put that knowledge out there, but I know it takes a lot of effort to write articles that are genuinely useful (rather than self-serving), correct them and then spend the money to put them into print. Of course, the same information can also be made available online for free! So, I direct you to the link below (or click on the picture above) to be taken to IDT’s webpage where a Special qPCR Issue of their magazine DECODED awaits.

And of course, you should make sure to contact You Do Bio to find out how to save money and have an opportunity to try out how good IDT’s PrimeTime qPCR assays really are. I have many customers who have made the switch and are very glad they did so!
