Study gene pathways or mimic disease states via gain-of-function assays. 
CRISPR activation offers transcriptional activation of endogenous genes – up to 50,000x basal expression levels. Or exogenously overexpress genes from nearly any species with our extensive cDNA and ORF collections.

CRISPR activation

Increase endogenous gene expression by up to 50,000x. 

Transcriptional up-regulation of endogenous genes within their native context.

Mammalian Gene Collection cDNA reagents

Overexpress your gene of interest.

Human, mouse, rat, and bovine cDNAs from the Mammalian Gene Collection.

ORF clones

5' and 3' UTRs removed for rapid protein expression.

Choose from Gateway or expression-ready ORF collections.

Non-mammalian cDNAs & ORFs

Chose from multiple model organisms.

Overexpress genes from Yeast, C. elegans, E. coli, D. rerio or X. laevis.
