Full Service Gene Expression

Capabilities – Full Service Transcript Expression – Transcript expression analysis has become a staple for understanding how genetic information coded in DNA is expressed in response to stimuli. Whether you’re working with a well studies model species or would like to explore expression profiles in a seldom-studied endemic species, the EGSB Team has you covered. The EGSB Team can employ RNAseq, microarray, and RT-qPCR methods to examine global or directed transcript expression in your species of interest. We can work with you to develop a customized study plan to meet nearly any R&D need. The EGSB Team has a well demonstrated track record of success in generating value from genomics investigations (see references below), and we can do the same for you:
