Flow Cytometry (Fixed/Permeabilized): 1:50
Storage
Supplied in 10 mM sodium HEPES (pH 7.5), 150 mM NaCl, 100 µg/ml BSA and 50% glycerol. Store at -20°C. Do not aliquot the antibody.
Protocol
Available protocols: Western Blotting, Immunofluorescence (Immunocytochemistry), Flow Cytometry (Fixed/Permeabilized)
Specificity / Sensitivity
PCM-1 (Q15) Antibody detects endogenous levels of total PCM-1 protein.
Species Reactivity: Human
Source / Purification
Polyclonal antibodies are produced by immunizing animals with a synthetic peptide corresponding to residues near the amino terminus of human PCM-1 protein. Antibodies were purified by protein A and peptide affinity chromatography.
Background
The centrosome is composed of a pair of centrioles surrounded by electron-dense pericentriolar material and functions as the microtubule-organizing center responsible for microtubule nucleation and spindle organization during cell cycle progression (1). Pericentriolar material 1 (PCM-1) is a large, 228 kDa protein associated with the centrosome in a cell cycle-dependent manner (2). PCM-1 localizes to small cytoplasmic granules called centriolar satellites (3). PCM-1 is required for the assembly of several centrosomal proteins, including centrin, pericentrin, ninein, NEK2, and CEP250 (4-8). Chromosomal translocations involving genes encoding PCM-1 and the tyrosine kinases Ret and Jak2 are associated with some cancers, including papillary thyroid carcinoma and myeloid leukemia (9-11).
