		Technical Data
C2098-89	CBX8, NT (Chromobox Protein Homolog 8, Polycomb 3 Homolog, Pc3, HPC3, Rectachrome 1, PC3, RC1)

Description:
Chromobox homolog 8 (CBX8 or Pc3) is a member of Drosophila Polycomb group gene family. The polycomb group (PcG) genes are essential for maintenance of appropriate expression patterns of developmental master regulators and thus are essential for proper development. Changes in expression of PcG proteins have been associated with cancer. CBX8 is involved in maintaining the transcriptionally repressive state of genes. It modifies chromatin, rendering it heritably changed in its expressibility. Structurally, CBX4 contains 1 chromo domain, which is 40 to 50 amino acids long.

Applications:
Suitable for use in ELISA and Western Blot. Other applications not tested.

Recommended Dilution:
ELISA: 1:1,000
Western Blot: 1:100-1:500
Optimal dilutions to be determined by the researcher.
