Background Information
CRKRS (Cdc2-related kinase, Arg/Ser), also named as cyclin-dependent kinase 12 (CKD12), belongs to CDC2/CDKX subfamily. CDK12 can form a heterodimeric complex with its activating partner, cyclin K, to regulate important cellular physiological processes that include transcriptional regulation, regulation of DNA damage repair genes such as BRCA1 and ATM, suppression of intronic polyadenylation, and susceptibility to PARP inhibitors (PMID: 30487607, 24240700, 31694772). CDK12 has 3 isoforms with the calculated molecular mass of 164/163/141 kDa, and the apparent molecular mass of 180-200 kDa due to some modifications (PMID 11683387, 22988298).

Reviews
What customers say
The single review for this product is negative (rated 1/5). The user performed a Western Blot on human liver lysate at a 1:1000 dilution and reported no signal at the expected molecular weight. Instead, they observed a couple of non-specific bands at lower molecular weights. Overall, the reviewer was unsatisfied with the antibody's performance under their experimental conditions.
The reviews below have been submitted by verified Proteintech customers who received an incentive for providing their feedback.
M (Verified Customer) (06-29-2021) | No Signal at all at the right size. A couple of non specific bands showed up at lower molecular weights.
