It is now quite easy to prevent adapter dimer formation during NGS library preps by using chemically-modified adapters.
In a poster presented at the recent ASHG 2014 meeting in San Diego, researchers from TriLink Biotechnologies described their innovative technology solving the adapter dimer problem in Next Generation Sequencing library prep.
Similar to the primer dimer problem observed when performing PCR (i.e. low molecular weight PCR by-products of primer-primer hybridization), adapter dimerization generates by products of NGS library prep that will greatly decrease the number of informative sequencing reads. This is particularly a problem for low-input studies and when working with small RNAs (e.g. miRNA).
TriLink’s expertise in chemistry-based solutions for biological problems has previously led to the creation of the CleanAmp™ product line. CleanAmp™ Primers, CleanAmp™ dNTPs and 2X PCR Master Mix employ heat labile modifications, similar to those on hot-start polymerases, to prevent primer dimerization or premature polymerase activity prior to a high-temperature activation step.
CleanAmp™ 7-deaza-dGTP is a chemistry-based solution allowing for the amplification of difficult GC-rich PCR products.

do you have a kit for microRNA library preparation?
The kit is in the final stages of beta-testing now. The catalog number at tebu-bio will be 040L-3203 when the product is released in the coming months. Checck the website http://www.tebu-bio.com from time to time.
thanks, do you have estimation how long it is going to be , weeks or months?
