| Description | DR1 Recombinant Human produced in E.Coli is a single, non-glycosylated polypeptide chain containing 196 amino acids (1-176 a.a.) and having a molecular mass of 21.6 kDa. The DR1 is fused to 20 amino acid His-Tag at N-terminus and purified by proprietary chromatographic techniques. |
| Expression host | Escherichia Coli. |
| Formulation | DR1 protein solution (0.5mg/ml) containing 20mM Tris-HCl buffer (pH8.0), 0.1mM PMSF, 0.1M NaCl & 10% glycerol. |
| Protein Background | DR1 is a phosphoprotein that inhibits both basal and activated levels of transcription. DR1 is phosphorylated in vivo which affects its interaction with TBP. DR1 has a histone fold motif at the amino terminus, a TBP-binding domain, and a glutamine- and alanine-rich region. By selectively repressing polymerases II and III, DR1 alters the physiological balance of transcriptional output in favor of polymerase I. |
| Purity | Greater than 85.0% as determined by SDS-PAGE. |
| Reagent Appearance | Sterile filtered colorless solution. |
| Stability | Store at 4°C if entire vial will be used within 2-4 weeks. Store, frozen at -20°C for longer periods of time. For long term storage it is recommended to add a carrier protein (0.1% HSA or BSA).Avoid multiple freeze-thaw cycles. |
| Synonyms | NC2, NC2-BETA, Negative cofactor 2-beta. |
