Clk2 Antibody

Cdc2 (Tyr15) polyclonal antibody was raised against a synthetic phosphopeptide corresponding to amino acid residues surrounding the phosphorylated-Tyr15 of human, mouse, rat and xenopus cdc2.

The antibody is purified by sequential chromatography on phospho- and non-phosphopeptide affinity columns. Antibody dilutions and tissue load should be based on tissue type and expected phosphorylation state. Western blots of SK-N-MC total cell extracts with phospho- and non-phosphopeptide competition were used to establish the phospho-specificity of the antibody. Immunolabeling of the Mr 34 kDa cdc2 protein is blocked by the Ser15 phosphopeptide used as antigen but not by the corresponding non-phosphopeptide. Initial recommended range of dilutions: 1:500 to 1:2000. Applications include Dot Blots (DB) and Western Blot (WB) . Suitability for Immunohistochemistry (IHC) has not been determined. Drosophila, human, mouse, rat and Xenopus have 100% amino acid sequence identity with the antigen used to raise the antibody. When internally tested under ideal conditions the working dilutions were 1:1000 for DB and WB.
