3F8_Purified_PLK-1_Antibody_1_050318
Total lysates (15 µg protein) from 293T and 293T/PLK-1 CRISPR/Cas9 knockout (KO) cells were resolved by electrophoresis (4-20% Tris-Glycine gel), transferred to nitrocellulose, and probed with 1:500 diluted (1 µg/mL) purified PLK-1 antibody, clone 3F8 (upper). Proteins were visualized by chemiluminescence detection using a 1:3000 diluted goat anti-mouse-IgG secondary antibody conjugated to HRP (Cat. No. 405306). 1:2000 dilution of Direct-Blot™ HRP anti-GAPDH Antibody (Cat. No. 649203) was used as a loading control (lower). Lane M: MW ladder.

    Whole cell extracts (15 µg protein) from serum starved HeLa untreated (-) or treated (+) with 200 ng/mL of Nocodazole for 20 hours were resolved on a 4-12% Bis-Tris gel and transferred to a PVDF membrane. The membrane was treated (+ LPP) or untreated (- LPP) with lambda protein phosphatase overnight at 4°C and probed with 0.5 µg/mL (1:1000 dilution) of purified anti-PLK-1 Phospho (Thr210) antibody (clone 2A3) for 2 hours at RT. Proteins were visualized by chemiluminescence detection using HRP Goat anti-mouse IgG Antibody (Cat. No. 405306) at a 1:3000 dilution. Direct-Blot™ HRP anti GAPDH Antibody (Cat. No. 607904) was used as a loading control at a 1:25000 dilution (lower). Purified anti-PLK-1 Antibody (Cat. No. 627702) was used as a pan PLK-1 loading control. Lane M: Molecular weight marker.

Description

PLK-1 (polo-like kinase 1) is a member of te serine/threonine protein kinase family, cdc5/polo subfamily. Highly homologous to polo-like kinase (Drosophila), PLK-1 contains two polo box domains with a predicted molecular weight of 68 kD. This nuclear protein is highly expressed in placenta and colon and has been shown to regulate cdc2/cyclin B through phosphorylation and activation of cdc25c phosphatase. PLK-1 may also be required for cell division; depletion of PLK-1 results in apoptosis. PLK-1 is upregulated by growth stimulating agents and is regulated by cell cycle position (highest in G2/M phase, declining to nearly undetectable levels after mitosis and throughout G1). PLK-1 is modified by phosphorylation (Thr210 is the major phosphorylation site in activated PLK-1 from mitotic cells) and has been shown to interact with nuclear distribution gene C. The 3F8 monoclonal antibody recognizes human and mouse PLK-1 and has been shown to be useful for Western blotting.
