公司供应的产品仅用于科研 产品名称:Recombinant Human LIF/Leukemia inhibitory factor Known as Leukemia Inhibitory Factor; LIF; Differentiation-Stimulating Factor; D Factor; Melanoma-Derived LPL Inhibitor; MLPLI; Emfilermin; LIF; HILDA Derived from E.coli Purity Greater than 95% as determined by reducing SDS-PAGE. Formulation Lyophilized from a 0.2 μm filtered solution of 20mM PB, 150mM NaCl, 0.02% Tween 20, pH 7.4. Shipping The product is shipped at ambient temperature. Storage Lyophilized protein should be stored at < -20°C, though stable at room temperature for 3 weeks.Reconstituted protein solution can be stored at 4-7°C for 2-7 days.Aliquots of reconstituted samples are stable at < -20°C for 3 months Reconstitution 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. Endotoxin Less than 0.1 ng/ug (1 IEU/ug) as determined by LAL test. Background Leukemia Inhibitory Factor (LIF) is a lymphoid factor that promotes long-term maintenance of embryonic stem cells by suppressing spontaneous differentiation. LIF has a number of other activities including cholinergic neuron differentiation, control of stem cell pluripotency, bone and fat metabolism, mitogenesis of certain factor dependent cell lines and promotion of megakaryocyte production in vivo. Human and murine mature LIF exhibit a 78% sequence identity at the amino acid level. Human LIF is equally active on human and mouse cells. Murine LIF is approximately 1000 fold less active on human cells than human LIF. Recombinant Human Leukemia Inhibitory Factor is produced by our E.coli expression system and the target gene encoding Ser23-Phe202 is expressed. 以下是公司正在热销的相关产品: 用于四环素、土霉素、金霉素、霉素、杆菌肽等的效价及残留的微生物学检定(中华人民共和国经典... 特价促销 抗生素检定培养基2号(低PH) 用于磷霉素、大观霉素、新霉素、罗红霉素等效价及残留的微生物学检定(中华人民共和国药典2010版)... 特价促销 抗生素检定培养基2号(高pH) 用于磷霉素、大观霉素、新霉素、罗红霉素等效价及残留的微生物学检定(中华人民共和国药典2010版... 特价促销 抗生素检定培养基2号(高PH) 用于庆大霉素效价的微生物学检定及藤黄八叠球菌菌悬液制备(中华人民共和国药典2010版)。 特价促销 抗生素检定培养基3号 用于两性霉素B的效价及残留的微生物学检定(中华人民共和国药典2010版)。 特价促销 抗生素检定培养基4号 供两性霉素B检定菌种啤酒酵母培养用(中华人民共和国药典2010版)。 特价促销 抗生素检定培养基5号 用于黏菌素等效价及残留的微生物学检定(中华人民共和国药典2010版)。 特价促销 抗生素检定培养基6号 BCL2L12 BCL2样12含脯氨酸蛋白抗体 特价促销 BCL2L15 BCL2样15促凋亡蛋白抗体 特价促销 Bcl2L2/BCL W Bcl-2样蛋白2抗体 特价促销 Bcl3 B细胞淋巴瘤蛋白3抗体 特价促销 Bcl-6/5 原癌基因Bcl-6抗体 特价促销 BCL7B BCL7B蛋白抗体 特价促销 BCL7C B细胞白血病/淋巴瘤蛋白7抗体 特价促销 Bcl-xL/BCL2L1/bcl-xs Bcl-xL蛋白抗体 特价促销 BCMA/CD269 B淋巴细胞成熟因子抗体 特价促销 BCMP11/AGR3 癌膜蛋白11抗体(前梯度同源蛋白2) 特价促销 Anti-TRPC2 TRPC2抗体(50 ul) Anti-TRPC2 TRPC2抗体(0.2 ml) Anti-TRPC1 TRPC1抗体(50 ul) Anti-TRPC1 TRPC1抗体(25 ul) Anti-TRPC1 TRPC1抗体(0.2 ml) Anti-TRPC1 (extracellular) TRPC1 (胞外)抗体(50 ul) Recombinant Human LIF/Leukemia inhibitory factorAnti-TRPC1 (extracellular) TRPC1 (胞外)抗体(25 ul) Anti-TRPC1 (extracellular) TRPC1 (胞外)抗体(0.2 ml) Anti-TRPA1 (extracellular) TRPA1 (胞外)抗体(50 ul) Anti-TRPA1 (extracellular) TRPA1 (胞外)抗体(25 ul)
