背景資料: MHC Class II is consists of 2 membrane spanning proteins. Each of these proteins is roughly 30 kDa， and has of two Globular domains， Alpha-1， Alpha-2， Beta-1 and Beta-2. The two regions farthest away from the membrane are alpha-1 and beta-1. The two proteins link without Covalent Bonds. The MHC Class II protein mainly presents peptides， which have been digested from external sources. MHC Class II is normally only expressed by Antigen Presenting Cells （APC） which digest foreign protein. Within the RER the alpha and beta proteins of the molecule， associate with each other， while a third protein called the "invariant chain，" is necessary for stabilizing the complex， without it， they will not associate. The MHC-invariant complex is then passed from the RER， into and out of， the Golgi body. It fuses with an Endocytic compartment， where an external protein has been sampled and degraded.

反應性: Recognizes most MHC class II haplotypes （b，f，p，q，r，s，u，v）， but weak against I-Ak。

其他: ProSpec 是一家全球著名細胞因子蛋白生產和研發(fā)的公司，具有20多年的生產經驗，專注于蛋白（重組及合成）生產研發(fā)。我們的核心產品包括：干擾素、白介素、骨蛋白、腫瘤壞死因子、成纖維生長因子、瘦素、干細胞因子、催乳素、表皮生長因子、胰島素樣生長因子、神經生長因子、集落刺激因子、激素、酶、病毒抗原以及各種重組蛋白等。n領先的生產工藝和規(guī)模使其可以提供毫克到克級蛋白，價格優(yōu)于同類公司。絕大部分產品是天然成熟型蛋白，而不含有標簽蛋白。考慮到大部分研究者希望能更靈活地配制蛋白溶液，ProSpec-Tany絕大部分產品沒有添加保護劑或鹽，這就對工藝提出了更高的要求。同時，ProSpec-Tany絕大部分產品為凍干粉，因此易于運輸和保存。
