EXPRESSION STUDIES
BioMedha offers a range of expression study assay formats to help provide a better understanding of disease biology, associated pathways, and compound efficacy.
Target expression pattern provides valuable insight in target validation, understanding biology, and molecular basis for compound effect, and therapeutic efficacy.
Different approaches measuring target expression
Expression studies can be performed at protein level, mRNA level, secretion level, at surface level, and expression by immunofluorescence.
Gene expression by qPCR (RT-PCR)
Figure-A: CD44, CXCL16, IL-1b and CD123 mRNA amplification in PMBCs, Monocytes, and Neutrophils and gene expression levels normalised to b-Actin housekeeping gene. Each test condition represents data from triplicate wells.
Protein expression by Western Blotting

Protein levels by ELISA
Figure-C: IL-22 levels in T cell supernatant
Expression by Flowcytometry
Figure-D: CD45 expression in healthy donor whole blood
Expression by Cell imaging
