{"gui_ge":"10ug","biao_da_su_zhu":"E.coli","biao_qian":"68AA","fen_zi_liang":"8 KDa","biao_guan_fen_zi_liang":"10 KDa, reducing conditions","xing_tai":"Lyophilized from a 0.2 μm filtered solution of 20mM PB, 150mM NaCl, pH 7.4.","chun_du":"Greater than 95% as determined by reducing SDS-PAGE.","nei_du_su_shui_ping":"Less than 0.001 ng\/µg (0.01 EU\/µg) as determined by LAL test.","rong_jie_fang_fa":"Always centrifuge tubes before opening.Do not mix by vortex or pipetting.\nIt is not recommended to reconstitute to a concentration less than 100μg\/ml.\nDissolve the lyophilized protein in distilled water.\nPlease aliquot the reconstituted solution to minimize freeze-thaw cycles. ","chu_cun_fang_fa":"Lyophilized protein should be stored at < -20°C, though stable at room temperature for 3 weeks.\nReconstituted protein solution can be stored at 4-7°C for 2-7 days.\nAliquots of reconstituted samples are stable at < -20°C for 3 months.","yun_shu_tiao_jian":"The product is shipped at ambient temperature.\nUpon receipt, store it immediately at the temperature listed below.","bei_jing_shuo_ming":"Stromal Cell-Derived Factor-1 (SDF-1) is a chemokine member of the intercrine family. SDF1 is expressed as five isoforms that differ only in the C terminal tail. SDF1α and SDF1β are identical except for the four residues present in the C-terminus of SDF1β but absent from SDF1α. SDF1 isoforms interact with CXCR4 and CXCR7 receptors on the cell surface, and can also bind syndecan4. SDF1 is known to influence lymphopoiesis, regulate patterning and cell number of neural progenitors, and promote angiogenesis. It also enhances the survival of myeloid progenitor cells."}
