Description: Recombinant Rat CD274 Protein is produced by mammalian expression system and the target gene encoding Ala18-Thr238 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: CD274 Alternative Names: B7H1; PDCD1L1; PDCD1LG1; PDL1; Programmed cell death 1 ligand 1; PD-L1; PDCD1 ligand 1; Programmed death ligand 1; B7 homolog 1; B7-H1; CD274Entrez Gene (Rat) : 499342SwissProt (Rat) : D4AE25Purity : Greater than 95% as determined by reducing SDS-PAGE.Chemical Structure : AFTITAPKDL YVVEYGSNVT MECRFPVEQK LDLLALVVYW EKEDKEVIQF VEGEEDLKPQ HSSFRGRAFL PKDQLLKGNA VLQITDVKLQ DAGVYCCMIS YGGADYKRIT LKVNAPYRKI NQRISMDPAT SEHELMCQAE GYPEAEVIWT NSDHQSLSGE TTVTTSQTEE KLLNVTSVLR VNATANDVFH CTFWRVHSGE NHTAELIIPE LPVPRLPHNR TVDHHHHHH Directions 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.
