Western Blotting (WB), Immunohistochemistry (Paraffin-embedded Sections) (IHC (p))
特异性
The antibody was affinity-purified from rabbit antiserum by affinity-chromatography using epitope-specific immunogen. Chk1 antibody AP02645PU detects endogenous levels of total Chk1 protein.
纯化方法
Immunoaffinity chromatography.
免疫原
The antiserum was produced against synthesized non-phosphopeptide derived from human Chk1 around the phosphorylation site of serine 317 (S-S-Sp-Q-P)
Suitable for use in Western blot (1: 500-1: 1000) and Immunohistochemistry (1: 50-1: 100). Other applications not tested. Optimal dilutions are dependent on conditions and should be determined by the user.

One mechanism by which checkpoints maintain the fidelity of cell cycle events is through blocking mitosis in response to unreplicated or damaged DNA. In most species this occurs through inhibiting activation of the cyclic dependent kinase Cdc2, which regulates entry into mitosis. Chk1, a kinase involved in the DNA damage checkpoint response can phosphorylate Cdc25C an activator of Cdc2. It is hypothesized that Chk1 induces serine 216 phosphorylation of Cdc25C and subsequent 14-3-3 binding negatively regulated Cdc25C, thus preventing it from activating Cdc2.Synonyms: CHEK-1, CHEK1, CHK1 checkpoint homolog, Serine/threonine-protein kinase Chk1
