货号 TMPK-00087
别名 MGC39850, ICOS, CVID1, CRP-1, CD278, AILIM
Inducible co-stimulator (ICOS), also called AILIM (activiation-inducible lymphocyte immunomediatory molecule) and CRP-1 (CD28-related protein-1), is a member of the growing CD28 family of immune costimulatory receptors. Other family members are CD28, CTLA-4 and PD-1. Human ICOS is a homodimeric type I transmembrane protein consisting of 199 amino acids (aa) with a putative 20 aa signal sequence, a 121 aa extracellular domain, a 23 aa transmembrane region, and a 35 aa cytoplasmic domain. ICOS Protein, Human, Recombinant (C136S & C137S, His) is expressed in HEK293 mammalian cells with C-His tag. The predicted molecular weight is 14.8 kDa and the accession number is Q9Y6W8-1.

| 种属 | Human |
| 表达系统 | HEK293 Cells |
| 标签 | C-His |
| 蛋白编号 | Q9Y6W8-1 |
| 蛋白构建 | Glu21-Phe141(C136S,C137S) |
| 蛋白纯度 | > 95% as determined by Tris-Bis PAGE; > 95% as determined by HPLC |
| 蛋白性状 | Lyophilized powder |
| 缓冲液 | Lyophilized from a solution filtered through a 0.22 μm filter, containing PBS (pH 7.4). Typically, 8% trehalose is incorporated as a protective agent before lyophilization. |
| 复溶方法 | Reconstitute the lyophilized protein in distilled water. The product concentration should not be less than 100 μg/ml. Before opening, centrifuge the tube to collect powder at the bottom. After adding the reconstitution buffer, avoid vortexing or pipetting for mixing. |
| 别名 | MGC39850, ICOS, CVID1, CRP-1, CD278, AILIM |
| 内毒素 | < 1 EU/μg by the LAL method. |
| 分子量 | 14.8 kDa (predicted). Due to glycosylation, the protein migrates to 35-40 kDa based on Tris-Bis PAGE result. |
| 运输方式 | In general, Lyophilized powders are shipping with blue ice. |
| 存储 | It is recommended to store recombinant proteins at -20°C to -80°C for future use. Lyophilized powders can be stably stored for over 12 months, while liquid products can be stored for 6-12 months at -80°C. For reconstituted protein solutions, the solution can be stored at -20°C to -80°C for at least 3 months. Please avoid multiple freeze-thaw cycles and store products in aliquots. |
