Anwendungsinformationen

Applikationshinweise:

Application Note: Anti-PC2 antibody has been tested for use in ELISA, WB, and IF. This affinity purified antibody is useful in immunofluorescence staining of cultured cells. In immunofluorescence, this antibody detects the expected discrete nuclear structure that is termed the PcG body, corresponding to the known localization of PC2. This affinity purified antibody is useful in western blotting using transfected cell lysates. Dilutions for western blotting represent a starting point dilution and further optimization may be required.  The antibody detects a band of approximately 82 kDa (predicted molecular weight: 61.4 kDa). The antibody has been successfully used to detect FLAG-tagged transfected hPC2 (see figure).  It detects a weak band that probably corresponds to endogenous PC2, however, a strong secondary band is also seen at 50kD in all cell lines thus far tested. This suggests that the antibody may also react with another highly expressed ubiquitous protein.  Reactivity in other immunoassays is unknown.

Hintergrund: Background: PC2 is the human homolog of the Drosophila 'Polycomb' (Pc) protein which has been identified as a gene family member associated with a cellular memory system that is responsible for the inheritance of gene activity by progeny cells. The human Pc homolog gene is more closely related to a Xenopus Pc homolog, XPc, than to a previously described human Pc homolog, CBX2 (hPc1). However, the hPc2 and CBX2/hPc1 proteins are shown to colocalize in interphase nuclei of human U-2 OS osteosarcoma cells, suggesting that the proteins are part of a common protein complex. The human protein is believed to function as a repressor of proto-oncogene activity and that interference with hPc2 function can lead to depression of proto-oncogene transcription and subsequently to cellular transformation.  Other reports describe PC2 as a protein that has SUMO E3 activity for the corepressors CtBP and CtBP2.
