产品简介：
| Background |
CD28 is a 44 kD glycoprotein, also known as Tp44 or T44. It is a member of the Ig superfamily, expressed on thymocytes, most peripheral T cells, and NK cells. In association with CD80 (B7-1) and CD86 (B7-2), CD28 acts as the second signal for T and NK cell activation and proliferation. The 37.51 antibody has been reported to augment in vitro T cell proliferation and cytokine production, and promote CTL development.

为解决转录因子（TF）染色过程中报告荧光蛋白信号丢失的问题，研究人员首先在CD4-Cre × EYFP小鼠脾细胞中比较了不同固定/破膜方案。进一步实验显示，Fix/Perm处理后的上清液中蛋白含量显著高于Triton X-100处理组，且通过抗GFP抗体捕获法可在Perm处理后的上清中检测到EYFP，但在先经Fix/Perm处理的样本中则无法检出——说明EYFP主要在Fix/Perm步骤中因固定不充分而泄漏。这些结果共同证实：荧光丢失源于固定强度不足，而非荧光团降解。 尽管2%多聚甲醛（PFA
