Chk1 (CHEK1) Rabbit Polyclonal Antibody

Specifications

Product Data
Applications	IHC, WB
Recommend Dilution	Suitable for use in Western blot (1:500-1:1000) and Immunohistochemistry (1:50-1:100).
Reactivity	Human
Host	Rabbit
Clonality	Polyclonal
Immunogen	The antiserum was produced against synthesized non-phosphopeptide derived from human Chk1 around the phosphorylation site of serine 317 (S-S-Sp-Q-P)
Specificity	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.

Concentration	lot specific
Purification	Immunoaffinity chromatography.
Conjugation	Unconjugated
Storage Condition	Store the antibody (in aliquots) at -20°C. Avoid repeated freezing and thawing.
Gene Name	checkpoint kinase 1
Database Link	Entrez Gene 1111 Human UniProt ID O14757
Background	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	CHEK1, CHEK-1
