A subtractive cDNA library is a collection of cDNA clones which is rare and likely to be poorly expressed. Subtractive cDNA libraries are produced using a proprietary technique which relies on the removal of dsDNA formed by hybridization between a control and test sample, thus eliminating cDNAs of similar abundance and retaining the transcripts which are differentially expressed or variable in sequence. As a leading supplier in cDNA library construction services, Creative Biogene can provide you with high-quality subtractive cDNA library construction services to ensure your satisfaction in a timely and professional manner.
