| Description | HMGN1 Human Recombinant produced in E.Coli is a single, non-glycosylated, polypeptide chain containing 108 amino acids (1-100 a.a.) and having a molecular mass of 11.7 kDa. HMGN1 protein is fused to an 8 amino acid His-Tag at C-terminus and purified by standard chromatography. |
| Expression host | Escherichia Coli. |
| Formulation | HMGN1 protein solution (0.5mg/ml) containing 20mM Tris-HCl pH-8, 1mM DTT, 0.1M NaCl, 0.1mM PMSF & 20% glycerol. |
| Inactivation | Protein quantitation was carried out by two independent methods:1. UV spectroscopy at 280 nm using the absorbency value of 0.57 as the extinction coefficient for a 0.1% (1mg/ml) solution. This value is calculated by the PC GENE computer analysis program of protein sequences (IntelliGenetics). 2. Analysis by RP-HPLC, using a calibrated solution of IL-13 as a Reference Standard. |
| Protein Background | HMGN1 binds to the inner side of the nucleosomal DNA therefore changing the interaction between the DNA and the histone octamer. HMGN1 participates in the development which maintains transcribable genes in an exceptional chromatin conformation. HMGN1 inhibits the phosphorylation of nucleosomal histones H3 and H2A by RPS6KA5/MSK1 and RPS6KA3/RSK2. |
| Purity | Greater than 95% 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 | HMG14, GC104230, High-Mobility Group Nucleosome Binding Domain 1. |
