Description
Data Sheet
| Antibody Properties | Reconstitute with sterile H20. Mix gently, wash the sides of the vial and wait 30-60 seconds before use. |
| Description | Recombinant Human HSBP1 produced in E.Coli is a single,non-glycosylated polypeptide chain containing 76 amino acids and having a molecular mass of 8.5 kDa. |
| Expression host | Escherichia Coli. |
| Formulation | The HSBP1 protein (1mg/ml) solution contains 20mM Tris-HCl buffer pH-7.5, 50mM NaCl, 1mM EDTA and 20% Glycerol. |
| Protein Background | The heat-shock response is elicited by exposure of cells to thermal and chemical stress and through the activation of HSFs (heat shock factors) results in the elevated expression of heat-shock induced genes. Heat shock factor binding protein-1 (HSBP1), is a 76-amino-acid protein that binds to heat shock factor 1(HSF1), which is a transcription factor involved in the HS response. During HS response, HSF1 undergoes conformational transition from an inert non-DNA-binding monomer to active functional trimers. HSBP1 is nuclear-localized and interacts with the active trimeric state of HSF1 to negatively regulate HSF1 DNA-binding activity. Overexpression of HSBP1 in mammalian cells represses the transactivation activity of HSF1. When overexpressed in C.elegans HSBP1 has severe effects on survival of the animals after thermal and chemical stress consistent with a role of HSBP1 as a negative regulator of heat shock response. |
| Protein content | By direct ELISA, 1:1,000 dilution will yield 0.2 O.D using alkaline phosphatase conjugated rabbit anti-mouse Ig (Jackson Laboratories). |
| Purity | Greater than 95.0% as determined by SDS-PAGE. |
| Reagent Appearance | Sterile filtered colorless solution. |
| Reconstitution | 1mg/ml in PBS (after reconstitution). |
| 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 | NPC-A-13, HSBP1, Heat shock factor-binding protein 1, Nasopharyngeal carcinoma-associated antigen 13, HSF1BP, DKFZp686D1664, DKFZp686O24200. |
| Titer | Antibody is shipped lyophilized at ambient temperature. |
