|WB||Use a concentration of 1 µg/ml. Detects a band of approximately 30 kDa (predicted molecular weight: 28 kDa).|
RelevanceControl of cell proliferation by Polycomb group proteins (PcG) is an important facet of cellular homeostasis and its disruption can promote tumorigenesis. CBX7 is a novel PcG protein which is found to control the growth of normal cells. CBX7 is a gene that encodes a Polycomb protein, as shown by sequence homology, its interaction with Ring1 and its localization to nuclear Polycomb bodies. CBX7 extends the lifespan of a wide range of normal human cells and immortalizes mouse fibroblasts by downregulating expression of the Ink4a/Arf locus. CBX7 does not inter-function or colocalize with Bmi1, and both can exert their actions independently of each other as shown by reverse genetics. CBX7 was highly expressed in three different prostate cancer cell lines and present at elevated levels in normal prostate. (Gil et al., 2004).

All lanes : Anti-cbx7 antibody (ab31765) at 1 µg/ml
Lane 1 : Hela nuclear Lysate
Lane 2 : Hela nuclear Lysate with Human cbx7 peptide (ab22423) at 1 µg/ml
Lysates/proteins at 20 µg per lane.
All lanes : Secondary ab: Alexa Fluor Goat polyclonal to Rabbit IgG (700)
Predicted band size: 28 kDa
Observed band size: 35 kDa why is the actual band size different from the predicted?
A clear band at the expected size appears in lane 1. This band is specifically blocked by the immunizing peptide in lane 2.
