WHSC2 Human Recombinant fused with a 20 amino acid His tag at N-terminus produced in E.Coli is a single, non-glycosylated, polypeptide chain containing 559 amino acids (1-539 a.a.) and having a molecular mass of 60.6kDa. The WHSC2 is purified by proprietary chromatographic techniques.
WHSC2 (NELF-A) is a protein factor required for DRB-sensitive transcription. WHSC2 is one of the 5 components of the multisubunit NELF complex which cooperates with DSIF to repress RNA polymerase II elongation. The Wolf-Hirschhorn syndrome is a multiple malformation syndrome characterized by mental and developmental defects resulting from a hemizygous deletion of the distal short arm of chromosome 4 (4p16.3).
Negative elongation factor A, NELF-A, Wolf-Hirschhorn syndrome candidate 2 protein, WHSC2, NELFA, FLJ10442, FLJ25112, P/OKcl.15.
Sterile Filtered colorless solution.
WHSC2 should be stored desiccated below -18°C. For long term storage it is recommended to add a carrier protein (0.1% HSA or BSA). Please prevent freeze-thaw cycles.
