背景介绍
CD28 (T-cell-specific surface glycoprotein CD28), also known as T44 and Tp44, is a 44 kD disulfide-linked homodimeric type I glycoprotein (PMID: 2162180). It is a member of the immunoglobulin superfamily and is expressed on most T lineage cells, NK cell subsets, and plasma cells (PMID: 2162180, 8386518). CD28 may affect in vivo immune responses by functioning both as a cell adhesion molecule linking B and T lymphocytes and as the surface component of a novel signal transduction pathway (PMID: 2162180, 3021470). CD28 binds both CD80 and CD86 with a highly conserved motif MYPPY in the CDR3-like loop (PMID: 15696168, 7964482). CD28 is considered a major co-stimulatory molecule, inducing T lymphocyte activation and IL-2 synthesis, and preventing cell death (PMID: 1348520).

文献和实验分别利用 CD3 与 CD28 的功能学抗体，以及 CD3/CD28 Streptamer® 激活扩增 T 细胞的实验步骤与实验结果。 CD3/CD28抗体法 1、实验步骤： 1.1 抗体包被 用无菌 PBS 将 anti-mouse CD3 抗体（克隆号：145-2C11）稀释至 5μg/ml，稀释后的抗体加入到 24 孔板中，每孔 400μl，4°C 包被过夜。（注：板子在加入抗体之前，先用无菌 PBS 润洗 2-3 遍，避免干孔）； 1.2 小鼠脾脏淋巴细胞分离（次日） 1. 将 70μm
实验原理 Dynabeads® CD3⁄CD28 CTS™ offer a simple method for isolation, activation and expansion of human T cells. Firstly, CD3 T cells are separated and concentrated from the apheresis product by magnetic cell separation
