重组人CDNF PeproTechDescription : Recombinant Human BMP-4 produced in E.Coli is a monomeric, non-glycosylated, Polypeptide chain containing 116 amino acids and having a molecular mass of 13009 Dalton. BMP-4 is purified by proprietary chromatographic techniques. Physical Appearance: Sterile Filtered White lyophilized (freeze-dried) powder. Formulation: BMP-4 was lyophilized from a concentrated (1mg/ml) sterile solution containing no additives. Solubility: It is recommended to reconstitute the lyophilized BMP-4 in sterile 18MΩ-cm H2O not less than 100μg/ml, which can then be further diluted to other aqueous solutions. Stability: Lyophilized BMP-4 although stable at room temperature for 3 weeks, should be stored desiccated below -18 C. Upon reconstitution BMP-4 should be stored at 4 C between 2-7 days and for future use below -18 C. For long term storage it is recommended to add a carrier protein (0.1% HSA or BSA). Please avoid freeze-thaw cycles. Purity: Greater than 95.0% as determined by: (a) Analysis by RP-HPLC. (b) Anion-exchange FPLC. (c) Analysis by reducing and non-reducing SDS-PAGE Silver Stained gel. Amino acid sequence: The sequence of the first five N-terminal amino acids was determined and was found to be Ser-Pro-Lys-His-His. Dimers and aggregates: Less than 1% as determined by silver-stained SDS-PAGE gel analysis. Applications: 1.Molecular standard (Western, ELISA) in studying secreted BMP-4 2.Preparing antibodies for BMP-4 monomer. 3.Molecule standard in detecting secreted BMP-4 in reduced SDS-PAGE.产品是我们的优势产品，质量可靠，性能稳定重组人CDNF PeproTech胎牛 Fetal Bovine Serum产于澳大利亚，血源以封闭的穿刺采自8月龄胎牛，产品经3次100nm过滤，在净化车间过滤包装.经严格检测确保无支原体，检测依据美国药典（USP）和美国联邦法规第九篇（9CFR），符合检测. 总蛋白：3.5～5.0%, 内含量≤1.0EU/ml 血红蛋白含量≤0.02% pH：6.7～8.0 渗透压（mom/Kg H2O）：240～340 无菌检验：阴性 支原体-展示：阴性 检验：阴性白细胞介素-1（interleukin-1，IL-1）是在感染和炎症状态下，由多种细胞产生的、有多方面生物学功能的细胞因子，其生物学作用十分广泛，主要包括参与介导炎症反应、调节免疫、调节机体代谢. IL-1分子重量为17.5KD，有两种类型：IL-1α和IL-1β，主要以IL-1β为主.IL-1受体（interleukin-1 receptor，IL-1R）包括Ⅰ型和Ⅱ型，此外还存在一种内源性IL-1受体拮抗剂 （interleukin-1 receptor antagonist，IL-1ra或IL-1γ），IL-1ra可以与IL-1受体结合，但是不引起相应的作用.炎症情况下，粒细胞巨噬细胞集落刺激因子（GM-CSF） 水平升高，它也能促进IL-1 的上调作用，增加 IL-1β的合成；另外关节滑膜细胞也可自分泌IL-1β. 产品描述 小鼠白介素-1β 重组蛋白是在大肠杆菌中重组表达的，是一条非糖基化的多肽链，包含有153个氨基酸，分子量为17500Da.该小鼠白介素-1β 重组蛋白**终由标准的色谱技术纯化出.
