Description：Recombinant Rat CD80 Protein is produced by mammalian expression system and the target gene encoding Vla30-Gln248 is expressed with a 6His tag at the C-terminus.Form：Lyophilized from a 0.2 μm filtered solution of PBS, pH7.4.Gene Symbol：CD80Alternative Names：CD28LG; CD28LG1; LAB7; T-lymphocyte activation antigen CD80; Activation B7-1 antigen; BB1; CTLA-4 counter-receptor B7.1; B7; CD80 Entrez Gene (Rat)： 25408; SwissProt (Rat)： O35187; Purity：Greater than 95% as determined by reducing SDS-PAGE.Chemical Structure：VGLFQISSGI VGQVSKSVRE KALLSCDYKF CSEEQSIHRI YWQKHDKMVL SVISGVPEVW PEYKNRTVYD IANNYSFSLL GLILSDRGTY TCVVQRYEGE SYVVKHLTTV ELSVRADFPT PNITESGNPS ADIKRITCFA SGGFPKPRLS WLENGRELNG INTTISQDPE SELYTISSQL DFNTTYDHFI DCFIEYGDAH VSQNFTWVKP PEDPPDEKQH HHHHHDirections for Use：Always centrifuge tubes before opening. Do not mix by vortex or pipetting. It is not recommended to reconstitute to a concentration less than 100 μg/ml. Dissolve the lyophilized protein in ddH2O. Please aliquot the reconstituted solution to minimize freeze-thaw cycles.Quality Control：Endotoxin: Less than 0.1 ng/µg (1 IEU/µg) as determined by LAL test.Storage/Stability：Lyophilized protein should be stored at -20°C, though stable at room temperature for 3 weeks. Reconstituted protein solution can be stored at 2-8°C for 2-7 days. Aliquots of reconstituted samples are stable at -20°C for 3 months.
