Recombinant Human NELFE, His-tagged

• Cat.No.: NELFE-192H
• Product Overview: NELFE, 1-380aa, Human, His tag, E.coli

Specification

• Species: Human
• Source: E.coli
• Tag: His
• Protein Length: 1-380aa
• Description: NELFE is a part of complex termed negative elongation factor (NELF) which represses RNA polymerase II transcript elongation. This protein bears similarity to nuclear RNA-binding proteins; however, it has not been demonstrated that this protein binds RNA. It contains a tract of alternating basic and acidic residues, largely arginine (R) and aspartic acid (D). Recombinant human NELFE protein, fused to His-tag at N-terminus, was expressed in E.coli and purified by using conventional chromatography techniques
• Form: Liquid. In 20mM Tris-HCl buffer (pH 8.0) containing 0.2M NaCl, 50% glycerol, 5mM DTT
• Molecular Mass: 45.6kDa (403aa) confirmed by MALDI-TOF
