Species cross-reactivity is determined by western blot.

Applications Key: W=Western Blotting, IP=Immunoprecipitation,

Specificity / Sensitivity

PLK2 (D5R2B) Rabbit mAb recognizes endogenous levels of total PLK2 protein.

Source / Purification

Monoclonal antibody is produced by immunizing animals with a synthetic peptide corresponding to residues surrounding Pro67 of human PLK2 protein.

Western Blotting

Western Blotting

Western blot analysis of extracts from HCT 116 cells, untreated (-) or treated with Doxorubicin #5927 (0.5 μM, 24 hr; +), using PLK2 (D5R2B) Rabbit mAb (upper), p53 (7F5) Rabbit mAb #2527 (middle), and β-Actin (13E5) Rabbit mAb #4970 (lower).



Immunoprecipitation of PLK2 from ACHN cell extracts using Rabbit (DA1E) mAb IgG XP® Isotype Control #3900 (lane 2) or PLK2 (D5R2B) Rabbit mAb (lane 3). Lane 1 is 10% input. Western blot was performed using PLK2 (D5R2B) Rabbit mAb.


At least five distinct polo-like kinases exist in mammalian cells: PLK1, PLK2, PLK3, PLK4/SAK, and the non-catalytic PLK5 protein (1). The p53-induced PLK2 functions in centriole duplication, as well as at spindle and S phase checkpoints (3-5). Research studies show that PLK2 expression is related to chemosensitivity in ovarian cancer. Downregulation of PLK2 expression in chemosensitive ovarian cancer cells is associated with a greater chance of relapse in patients following specific treatment regimens (6). PLK2 can phosphorylate α-synuclein at Ser129, which is a site shown to be involved in diseases of the central nervous system (7,8). Polo-like kinase 2 also phosphorylates GEFs and GAPs, regulating Ras and Rap small GTPase function in neurons (9).
