Description
Polo-like kinase (PLK1) is a serine/threonine kinase with structural similarities to Drosophila's Polo kinase and the Cdc5p of Saccharomyces cerevisiae. Like its invertebrate counterparts, PLK1 activity is required for DNA synthesis and is regulated throughout the cell cycle. Furthermore, PLK1 is highly expressed in primary tumors. It associates with the mitotic spindle during mitosis suggesting that, in addition to its role during S phase, PLK1 may play a role during chromosome segregation. This is consistent with its potential role in cancer development. Threonine 210 (T210) is one of the major phoshorylation sites in activated PLK1 obtained from human mitotic cells.
The K50-483 monoclonal antibody recognizes the phosphorylated T210 of human PLK1.

Alexa Fluor® 647 conjugates are highly photostable and remain fluorescent over a broad pH range. The excitation and emission maxima are nearly identical to those of APC. However, APC tends to be brighter while Alexa Fluor® 647 is more optimal for intracellular applications. This fluorochrome exhibits uncommon photostability, making it an ideal choice for use in fluorescence microscopy. Due to nearly identical excitation and emission properties but different spillover characteristics, APC and Alexa Fluor® 647 cannot be used simultaneously.

Preparation and Storage
Store undiluted at 4°C and protected from prolonged exposure to light. Do not freeze.
The antibody was conjugated to Alexa Fluor® 647 under optimum conditions, and unreacted Alexa Fluor® 647 was removed.
The monoclonal antibody was purified from tissue culture supernatant or ascites by affinity chromatography.
