Product Specific Information
Recombinant rabbit monoclonal antibodies are produced using in vitro expression systems. The antibody DNA sequences from immunoreactive rabbits are cloned and screened to select optimal clones for production.
Key advantages include:
- Enhanced specificity and sensitivity
- Lot-to-lot consistency
- Animal origin-free formulation
- Broad immunoreactivity due to the large rabbit immune repertoire
Target Information
CHEK1 (CHK1) is a serine/threonine protein kinase that plays a critical role in maintaining genomic integrity when DNA damage occurs. It mediates DNA damage-induced checkpoint control and prevents replication under compromised DNA conditions.
Inhibition of CHK1 can induce mitotic catastrophe in p53-deficient cancer cells, making CHK1 an attractive therapeutic target for cancer treatment, particularly since about 50% of human cancers lack functional p53.
For Research Use Only. Not for use in diagnostic procedures. Not for resale without express authorization.
