产品描述：Recombinant Human CXCL12 Protein (Met18-Met93) is produced by E. coli expression system and the target gene encoding Met18-Met93 is expressed.产品形式：Lyophilized from a 0.2 μM filtered solution of 20mM Tris-HCl, 400mM NaCl, pH 8.5.基因名称：CXCL12相关名称：SDF1; SDF1A; SDF1B; Stromal cell-derived factor 1; SDF-1; hSDF-1; C-X-C motif chemokine 12; Intercrine reduced in hepatomas; IRH; hIRH; Pre-B cell growth-stimulating factor; PBSF 基因编号(人)： 6387; 蛋白编号(人)： P48061; 纯度：Greater than 95% as determined by SEC-HPLC and reducing SDS-PAGE.化学结构：MSDGKPVSLS YRCPCRFFES HVARANVKHL KILNTPNCAL QIVARLKNNN RQVCIDPKLK WIQEYLEKAL NKRFKM使用指导：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 1X PBS. Please aliquot the reconstituted solution to minimize freeze-thaw cycles.质量控制：Endotoxin: Less than 0.1 ng/μg (1 IEU/μg) as determined by LAL test.储存效期：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.
