特别应用

CAR-T细胞活化扩增：

CAR-T免疫疗法

继诺华和Kite公司两款CAR-T细胞治疗被FDA批准，2017年被媒体评为CAR-T疗法的元年。

CAR T细胞免疫疗法中，因为纯化自体抗原呈递细胞（APCs）用于T细胞活化需要好几个额外步骤，增加获得CAR T细胞产品强度和难度。因此研究者开发了另外一种更标准化、更具效率的T细胞活化方法，比如使用抗CD3/抗CD28单克隆抗体（anti-CD3/anti-CD28 monoclonal antibodies）。

而Dynabeads® Human T-Activator CD3/CD28 这种微珠可以提供 T 细胞活化和扩增所需的原始和共刺激信号，通过使抗 CD3和抗 CD28 抗体与 Dynabeads® 结合，更加速扩增。

推荐PeproTech抗CD3/抗CD28单克隆抗体产品

T细胞活化抗人CD3单克隆抗体（Functional，clone: OKT3）可以与TCR复合物结合，激活T细胞。SAFIRE(Sodium Azide Free Immensely Reduced Endotoxins) 类产品是BioGems品牌下的功能性抗体产品。

About Dynabeads® Human T-Activator CD3/CD28

Dynabeads® Human T-Activator CD3/CD28 offer a simple method for activation and expansion of T cells that does not require feeder cells (antigen-presenting cells) or antigen. The uniform 4.5 µm diameter, inert, superparamagnetic beads are similar in size to antigen-presenting cells, and are covalently coupled to anti-CD3 and anti-CD28 antibodies. These two antibodies provide primary and co-stimulatory signals, optimized for efficient T cell activation and expansion. Expansion of the T cell population can be stimulated using recombinant IL-2, and after activation or expansion, the magnetic beads can be easily removed using a DynaMag™ magnet. For expansion of antigen-specific T cells from T cell clones or T cell lines, we recommend using Dynabeads® Human T-Activator CD3/CD28/CD137.

Starting samples

Start with mononuclear cells (MNCs)/peripheral blood mononuclear cells (PBMCs) from either whole blood or buffy coat, or T cell subsets including CD3+ T cells, CD4+ or CD8+ T cells, or regulatory T cells.

Downstream applications

The activated T cells can be analyzed shortly after activation (for transfection/transduction or to study TCR signaling, proteomics, gene expression, etc.). T cells can be left in culture to differentiate into T helper cell subsets or expansion of polyclonal/antigen-specific T cells.

For Research Use Only. Not for use in diagnostic procedures.
