Anti-COBRA1, ID (COBRA1, KIAA1182, NELFB, Negative elongation factor B, Cofactor of BRCA1) (Azide Fr

NELFB is a subunit of negative elongation factor (NELF), which also includes NELFA (WHSC2, MIM 606026), either NELFC or NELFD (TH1L, MIM 605297), and NELFE (RDBP, MIM 154040). NELF acts with DRB sensitivity-inducing factor (DSIF), a heterodimer of SPT4 (SUPT4H1, MIM 603555) and SPT5 (SUPT5H, MIM 602102), to cause transcriptional pausing of RNA polymerase II (see MIM 180660) (Narita et al., 2003 [PubMed 12612062]). Applications: Suitable for use in Western Blot and ELISA. Other applications have not been tested. Recommended Dilution: Optimal dilutions to be determined by the researcher. Storage and Stability: Store product at 4°C if to be used immediately within two weeks. For long-term storage, aliquot to avoid repeated freezing and thawing and store at -20°C. Aliquots are stable at -20°C for 12 months after receipt. Dilute required amount only prior to immediate use. Further dilutions can be made in assay buffer. For maximum recovery of product, centrifuge the original vial after thawing and prior to removing the cap., , Note: Applications are based on unconjugated antibody.
