Introduction
Transcription Elongation Factor A (SII)- 2 (TCEA2) is located in the nucleus, where it serves as an SII class transcription elongation factor. Elongation factors in this class are responsible for discharging RNA polymerase II ternary complexes from transcriptional arrest at template-encoded arresting sites. TCEA2 interacts with general transcription factor IIB, a basal transcription factor.
Description
TCEA2 Human Recombinant produced in E.Coli is a single, non-glycosylated polypeptide chain containing 322 amino acids (1-299 a.a) and having a molecular mass of 36kDa.
TCEA2 is fused to a 23 amino acid His-tag at N-terminus & purified by proprietary chromatographic techniques.
Source
E.coli.
Physical Appearance
Sterile Filtered colorless solution.
Formulation
TCEA2 protein solution (0.25mg/ml) containing 20mM Tris-HCl buffer (pH 8.0), 1mM DTT, 30% glycerol and 0.25M NaCl.
