Tested Applications

• Positive WB detected in: HEK-293 cells, A549 cells, HeLa cells, MDA-MB-453s cells, U2OS cells, Jurkat cells, mouse testis tissue, rat testis tissue
• Positive IF/ICC detected in: U2OS cells
• Positive FC (Intra) detected in: Ramos cells

PLK1 expression is low or nonexistent in normal tissues, but high in tumor tissues.

Recommended dilution

• Western Blot (WB): WB : 1:1000-1:8000
• Immunofluorescence (IF)/ICC: IF/ICC : 1:50-1:500
• Flow Cytometry (FC) (INTRA): FC (INTRA) : 0.40 ug per 10^6 cells in a 100 µl suspension

It is recommended that this reagent should be titrated in each testing system to obtain optimal results.

Background Information

PLK1(Polo-like kinase 1), also named as PLK and STPK13, belongs to the protein kinase superfamily, Ser/Thr protein kinase family and CDC5/Polo subfamily. PLK1 is a Serine/threonine-protein kinase that performs several important functions throughout M phase of the cell cycle, including the regulation of centrosome maturation and spindle assembly, the removal of cohesins from chromosome arms, the inactivation of APC/C inhibitors, and the regulation of mitotic exit and cytokinesis.The localization of Polo changes during the cell cycle. In interphase, Polo shows a mostly diffuse cytoplasmic localization. Polo becomes concentrated on centrosomes from early prophase and appears on centromeres or kinetochores from late prophase, before nuclear envelope breakdown (NEB). After anaphase onset, Polo relocalizes to the central spindle and remains enriched at the midbody ring in late stages of cytokinesis (PMID: 29167465).
