The Phospho-Chk1-S345 Monoclonal Antibody (CAB21009) is a high-quality antibody developed for reliable detection and analysis of target proteins. CHK1 is a key regulator of the cell cycle and is activated in response to DNA damage, serving to halt cell cycle progression and allow for DNA repair. Phosphorylation of CHK1 at serine 345 is a critical event in its activation and function.This monoclonal antibody, developed and validated for use in various applications including Western blot, immunofluorescence, and immunoprecipitation, specifically recognizes CHK1 when phosphorylated at serine 345.
This antibody is validated for use in WB, ELISA applications and has demonstrated reactivity against Human, Mouse samples.

The protein encoded by this gene belongs to the Ser/Thr protein kinase family. It is required for checkpoint mediated cell cycle arrest in response to DNA damage or the presence of unreplicated DNA. This protein acts to integrate signals from ATM and ATR, two cell cycle proteins involved in DNA damage responses, that also associate with chromatin in meiotic prophase I. Phosphorylation of CDC25A protein phosphatase by this protein is required for cells to delay cell cycle progression in response to double-strand DNA breaks. Several alternatively spliced transcript variants have been found for this gene.
