This product came to my attention very recently, after talking to a customer. Access all available Molecular Identifier (MID) tags available. MIDs will allow identifying tags to be placed on multiple libraries so that they may be multiplexed for sequencing.
If you are a researcher who is using the 454 GS FLX system, it is possible to get the entire MID library from IDT (120 MIDs) from IDT. For customers that need more MIDs than the twelve supplied by 454 in the GS FLX Titanium Rapid Library MID Adaptors Kit, this Extended List provides additional sequences that have been optimized for MID applications.
