Data Examples
Detection of Human, Mouse, and Rat Chk1 by Western Blot. Western blot shows lysates of NRK rat normal kidney cell line, U2OS human osteosarcoma cell line, MCF‑7 human breast cancer cell line, CEM human T‑lymphoblastoid cell line, and Balb/3T3 mouse embryonic fibroblast cell line. PVDF membrane was probed with 1 µg/mL of Goat Anti-Human/Mouse/Rat Chk1 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF1630) followed by HRP-conjugated Anti-Goat IgG Secondary Antibody (Catalog # HAF017). A specific band was detected for Chk1 at approximately 57 kDa (as indicated). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 1.

Background: Chk1
The Chk1 checkpoint kinase is an integral member of a signaling cascade that controls cell cycle progression. In response to genotoxic stress, Chk1 is phosphorylated by ATM or ATM-related kinases. In turn, Chk1 phosphorylates downstream effectors, such as p53 or the Cdc25 phosphatases to halt cell cycle progression and allow time for repair of incurred damage.
