NELF-B is a subunit of negative elongation factor (NELF), which also includes NELF-A (WHSC2), either NELF-C or NELF-D (TH1L), and NELF-E (RDBP). NELF acts with DRB sensitivity-inducing factor (DSIF), a heterodimer of SPT4 (SUPT4H1) and SPT5 (SUPT5H), to cause transcriptional pausing of RNA polymerase II. COBRA1 was initially identified in a yeast two-hybrid screen using the BRCT1 domain of BRCA1 as bait.\u003c\/p\u003e\u003cp\u003e\u003cb\u003eImmunogen\u003c\/b\u003e: E. coli-derived human COBRA1 recombinant protein (Position: M1-E252).\u003c\/p\u003e\u003cp\u003e\u003cb\u003eClonality\u003c\/b\u003e: Polyclonal\u003c\/p\u003e\u003cp\u003e\u003cb\u003eContents\u003c\/b\u003e: Each vial contains 4mg Trehalose, 0.9mg NaCl, 0.2mg Na2HPO4, 0.05mg NaN3.\u003c\/p\u003e\u003cp\u003e\u003cb\u003ePurification\u003c\/b\u003e: Immunogen affinity purified.\u003c\/p\u003e\u003cp\u003e\u003cb\u003eReconstitution\u003c\/b\u003e: Add 0.2ml of distilled water will yield a concentration of 500ug\/ml.\u003c\/p\u003e\u003cp\u003e\u003cb\u003eReference\u003c\/b\u003e: 1.
