This Rabbit Polyclonal antibody specifically detects PLK1 in WB, IHC (p) and EIA. It exhibits reactivity toward Human, Mouse, Rat, Xenopus laevis, Dog, Zebrafish (Danio rerio), Pig, Chimpanzee and Chicken.
This antibody is specific for phosphorylated Human Plk-1 protein at the pThr210 residue. Cross reactivity with Plk-1 protein homologues from C.elgans and Honeybee may also occur as sequence homology varies by one amino acid residue in this sequence. Reactivity with Plk-1 protein from other sources is not known. Minimal reactivity is expected with the non-phosphorylated form of the protein.
Cross-Reactivity (Details)
Species reactivity (expected):Chimpanzee, Pig, Chicken, Mouse, Rat, Xenopus, Dog, Mosquito, Zebrafish, Starfish, Sea urchin and Fruit Fly. Species reactivity (tested):Human.
Purification
Immunoaffinity Chromatography using phospho peptide coupled to agarose beads followed by solid phase adsorption(s) against non-phospho peptide and non-specific peptide to remove any unwanted reactivities
Immunogen
Synthetic phospho peptide corresponding aa 205-214 of Human Polo-like kinase 1 (Plk1) protein
ELISA (1/3,000-1/12,000). Immunohistochemistry on Paraffin Sections (1/200-1/1,000). This antibody is positive byIHC on kidney, liver, cancer, thyroid and lymphocyte tissue. Western blot (1/200-1/2,000). Expect a band approximately 68 kDa in size correspondingto Plk-1. Other applications not tested. Optimal dilutions are dependent on conditions and should be determined by the user.

Background
Polo-like kinase 1, also known as Plk-1, serine-threonine protein kinase 13 and STPK13, may be required for cell division and have a role during G1 or S phase and is associated with the phosphorylation of cyclin B1. Phosphorylation of Plk-1 on T210 contributes to proper mitotic progression. Plk-1 has a nuclear localization and accumulates to a maximum during the G2 and M phases, declines to a nearly undetectable level following mitosis and throughout G1 phase, and then begins to accumulate again during S phase. Plk-1 is a member of the Ser/Thr protein kinase family and the CDC5/Polo subfamily and contains 2 POLO box domains.Synonyms: PLK-1, Polo-like kinase 1, STPK13, Serine/threonine-protein kinase PLK1
