Technical Data
CBX4 (chromobox homolog 4 (Drosophila Pc class), Chromobox protein homolog 4, E3 SUMO-protein Ligase CBX4, MGC143697, MGC143698, mPc2, MPc2, Pc2, PC2, Polycomb 2 Homolog)
The family of Heterochromatin Proteins ("Chromobox Homolog", CBX) are highly conserved adapter molecules, which have important functions in the cell nucleus. These functions include gene repression by heterochromatin formation, transcriptional activation, regulation of binding of cohesion complexes to centromere, sequesteration of genes to nuclear periphery, transcriptional arrest, maintenance of heterochromatin integrity, gene repression at single nucleosome level, and gene repression by heterochromatization of euchromatin.

Suitable for use in Western Blot. Other applications not tested.

Recommended Dilution:
Western Blot: 0.5-2ug/ml
Optimal dilutions to be determined by the researcher.

Positive Control:
NIH/3T3 nuclear extract, HeLa cell nuclear extract

Storage and Stability:
May be stored at 4C for short-term only. For long-term storage and to avoid repeated freezing and thawing, aliquot and store at -20C. Aliquots are stable for at least 12 months at -20C. For maximum recovery of product, centrifuge the original vial after thawing and prior to removing the cap. Further dilutions can be made in assay buffer.
