Description

CBX1 Human Recombinant produced in E.coli is a single, non-glycosylated polypeptide chain containing 205 amino acids (1-185) and having a molecular mass of 23.6kDa (molecular weight on SDS-PAGE will appear higher).The CBX1 is fused to a 20 amino acid His-

Protein Background

CBX1 is an enriched heterochromatin which belongs to the heterochromatin protein family. The centromeres related CBX1 identifies and binds histone H3 tails methylated at 'Lys-9', causing epigenetic repression. Collaboration with lamin B receptor (LBR) can

Expression host

Escherichia Coli.

Synonyms

Chromobox homolog 1, CBX, M31, HP1-BETA, HP1Hs-beta, MOD1, Heterochromatin protein 1 homolog beta, Modifier 1 protein, p25beta, Chromobox homolog 1 (Drosophila HP1 beta), Heterochromatin protein p25.

Reagent Appearance

CBX1 is supplied as a sterile filtered clear solution.

Stability

Store at 4°C if entire vial will be used within 2-4 weeks. Store, frozen at -20°C for longer periods of time. For long term storage it is recommended to add a carrier protein (0.1% HSA or BSA).Avoid multiple freeze-thaw cycles.
