Rabbit polyclonal to Chk1 (phospho S317)
Chk1(Phospho-Ser317) Antibody detects endogenous levels of Chk1 only when
phosphorylated at Serine 317.
Synthetic phosphopeptide derived from human Chk1 around the phosphorylation site of Serine 317.
Shipped at 4°C. Upon delivery aliquot and store at -20°C. Avoid freeze / thaw cycles.
Preservative: 0.02% Sodium Azide

Immunogen affinity purified
ab38518 was affinity-purified from rabbit antiserum by affinity-chromatography using epitope-specific phosphopeptide. The antibody against non-phosphopeptide was removed by chromatography using non-phosphopeptide corresponding to the phosphorylation site.
