产品描述：Recombinant Human LIF Protein is produced by E. coli. It is a single non-glycosylated polypeptide chain containing 180 amino acids with a molecular mass of 19.7 kD.产品形式：Lyophilized from a 0.2 μM filtered solution of 20mM PB, 150mM NaCl, 0.02% Tween 20, pH 7.4基因名称：LIF相关名称：HILDA; Leukemia inhibitory factor; LIF; Differentiation-stimulating factor; D factor; Melanoma-derived LPL inhibitor; MLPLI; Emfilermin 基因编号(人)： 3976; 蛋白编号(人)： P15018; 纯度：Greater than 95% as determined by SEC-HPLC and reducing SDS-PAGE.化学结构：MSPLPITPVN ATCAIRHPCH NNLMNQIRSQ LAQLNGSANA LFILYYTAQG EPFPNNLDKL CGPNVTDFPP FHANGTEKAK LVELYRIVVY LGTSLGNITR DQKILNPSAL SLHSKLNATA DILRGLLSNV LCRLCSKYHV GHVDVTYGPD TSGKDVFQKK KLGCQLLGKY KQIIAVLAQA F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.
