Cat#:RP-1651H;Product Name:Recombinant Human XRCC5 & XRCC6 Heterodimer Protein;Synonym:XRCC5, XRCC6;Description:A DNA sequence encoding the XRCC5 (P13010) (Met 1-Ile 732) was fused with a polyhistidine tag at the N-terminus, constructed the plasmid 1; A DNA sequence encoding the XRCC6 (P12956) (Met 1-Asp 609) was fused with a polyhistidine tag at the N-terminus, constructed the plasmid 2. The two plasmids were co-expressed and the heterodimer was purified.;Source:Baculovirus-Insect Cells;Predicted N Terminal:His & His;Molecular Characterization:The recombinant heterodimer of human XRCC5/XRCC5 comprises 1379 (751 + 628) amino acids and has a calculated molecular mass of 157 (85 + 72) kDa. The apparent molecular mass of rh XRCC5/XRCC5 heterodimer is approximately 70 & 85 kDa respectively in SDS-PA;Purity:Greater than 90 % as determined by SDS-PAGE;Endotoxin:< 1.0 EU per ug of the protein as determined by the LAL method;Bioactivity:Please contact us for detailed information;Formulation:Lyophilized from sterile 20mM Tris, 500mM NaCl, 10% gly, pH 8.0;Stability:Recombinant Proteins are stable for up to 1 year from date of receipt at -70℃;Reconstitution:Please see related COA for specific instructions.;Storage:Avoid repeated freeze-thaw cycles. In lyophilized state for 1 year (4-8℃); Upon reconstitution under sterile conditions for 2 weeks (4-8℃) or 3 months (-20℃ to -70℃).;
