Stability Test: The thermal stability is described by the loss rate of the target protein. The loss rate was determined by accelerated thermal degradation test, that is, incubate the protein at 37oC for 48h, and no obvious degradation and precipitation were observed. (Referring from China Biological Products Standard, which was calculated by the Arrhenius equation.) The loss of this protein is less than 5% within the expiration date under appropriate storage condition.
Protein bands: 10kDa, 14kDa, 18kDa, 22kDa, 26kDa, 33kDa, 44kDa and 70kDa.
Double intensity bands: The 26kDa, 18kDa, 10kDa bands are at double intensity to make location and size approximation of proteins of interest quick and easy.

文献和实验填料 根据亲和层析的几种应用方向,亲和层析的填料主要分为标签蛋白纯化填料、抗体及抗体片段纯化填料、族特异性亲和填料以及预活化填料四种。 1. 标签蛋白纯化填料 为了简化纯化流程以及方便后期的检测,在进行重组蛋白表达时往往会加入标签。常用的标签包括His标签、GST标签、Strep标签及MBP标签等 (表8)。His标签由于分子量很小,几乎不会影响靶蛋白结构和功能而被广泛使用。GST和MBP标签常用于促进蛋白的可溶表达,尤其对于难表达的真核细胞蛋白和病毒蛋白有很好的促溶表达能力。Strep
坏死因子(Tumornecrosisfactor,TNF)根据其产生来源和结构不同,可分为TNF-α和TNF-β两类,前者由单核-巨噬细胞产生,后者由活化T细胞产生,又名淋巴毒素。TNF除具有杀伤肿瘤细胞外,还有免疫调节、参与发热和炎症的发生。 5,转化生长因子-β家族(Transforminggrowthfactor-βfamily,TGF-βfamily)主要包括TGF-β1、TGF-β2、TGF-β3、TGFβ1β2以及骨形成蛋白(BMP)等。 6.趋化因子家族(Chemokinefamily)包括两个亚族:(1)C-X-C
成像颜色褐色介于蓝色与蓝紫色之间(可用于双染)棕红色蓝紫色毒性有(疑有治癌作用)无有无选择 R&D Systems 抗体的四大理由:Purification-采用抗原亲和纯化的方式对抗体进行纯化,纯化后的抗体具有更好的特异性;Antigens-使用重组蛋白作为制备抗体的免疫原,大大提高了抗体对抗原的特异性识别能力;Specificity-批次间稳定性的严格控制,有效保证了 R&D Systems 目录抗体在识别抗原时的特异性;Source-多种宿主来源,以及多种单抗或多抗的选择,为客户提供了更丰富、更
