Our cDNA libraries live up to expectations!
Greater than 1x10E6 independent clones
More than 85% plasmids containing inserts
Average insert size at least 1.2 kb
Technology information
Our high quality cDNA's are constructed using a brand new technology. We utilize the specific features of MMLV-based reverse transcriptase to create full length enriched double stranded cDNA from total or polyA+ RNA samples. Differences in length of the 5’ adaptor primer ensure transcription of all three reading frames. Normalization of cDNA is confirmed by qPCR using two high abundant marker genes (Figure 1). Normalized cDNAs are amplified by representational PCR and cloned directionally into the library vector of choice.
With our extensive know-how in library construction we guarantee highest quality with reasonable pricing.

- Figure 1: qPCR of normalized and not normalized human spleen cDNA. For Actin, a decrease of 75.8% was reached. For hGAPDH, the decrease was 60.6%. The amount of these two high abundant cDNAs was lowered, increasing the quality of the cDNA library.
