Cat#:RP-2196H;Product Name:Recombinant Human Bcl 2 Protein (minus BH4 domain);Synonym:Apoptosis regulator Bcl-2, BCL2, B-cell CLL/lymphoma 2, Bcl-2.;Description:Bcl-2 Des BH4 domain (10-30 residues) Protein produced in E.coli is a single, non-glycosylated polypeptide chain containing 197 amino acids 1-9 and 31-218. The Bcl-2 is expressed as His-Tag fusion protein and purified by proprietary chromatographic techniques.;Source:E.coli;Purity:Greater than 95.0% as determined by: (a) Analysis by RP-HPLC. (b) Analysis by SDS-PAGE.;Bioactivity:Please contact us for detailed information;Formulation:The protein contains 10mM Tris-HCl pH-8, 1mM EDTA and 250mM NaCl.;Stability:Recombinant Proteins are stable for up to 1 year from date of receipt at -70℃;Reconstitution:Suspend Bcl-2 in 100µl of 0.5M Acetic acid, over night at 4°C. Dilute 10 fold into selected buffer system. BCL-2 has tendency to form intramolecular disulfide bond, 5mM DTT is recommended in assay buffer. When running SDS-PAGE gel, 10mM DTT is recommended;Storage:Lyophilized Bcl-2 although stable at room temperature for 3 weeks, should be stored desiccated below -18°C. Upon reconstitution Bcl-2 should be stored at 4°C between 2-7 days and for future use below -18°C. For long term storage it is recommended to add a carrier protein (0.1% HSA or BSA). Please prevent freeze-thaw cycles.;
