Dynabeads Human T-Activator CD3/CD28 免疫磁珠通過偶聯(lián)CD3/CD28單抗，活化擴增人T細胞。

產品英文名 Dynabeads Human T-Activator CD3/CD28 for T Cell Expansion and Activation

產品中文名 Dynabeads Human T-Activator CD3/CD28 免疫磁珠

產品介紹 Dynabeads Human T-Activator CD3/CD28 用于活化和擴增人 T 細胞和 T 細胞克隆，以作研究之用。Dynabeads CD3/CD28 T Cell Expander 提供了活化和擴增 T 細胞的簡單方法，無需抗原呈遞細胞或抗原。 Dynabeads Human T-Activator CD3/CD28 是均勻的 4.5 m 超順磁珠，與抗 CD3 和抗 CD28 單克隆抗體的優(yōu)化混合物偶聯(lián)。 通過使抗 CD3 和抗 CD28 抗體與 Dynabeads 結合，這種微珠可以提供 T 細胞活化和擴增所需的原始和共刺激信號。

Dynabeads免疫磁珠特點

Dynabeads Human T-Activator CD3/CD28 are for the activation and expansion of human T cells. Advantages of Dynabeads Human T-Activator CD3/CD28:

Activation of T cells without the need for feeder cells

T細胞活化無需滋養(yǎng)層細胞

Activated cells that retain in vivo-like function

活化細胞功能同體內培養(yǎng)

Maximum reproducibility without contamination by soluble antibodies or mitogens

zui高可重復性，沒有抗體溶解和絲裂原污染。

From 100- to 1,000-fold T cell expansion

特別應用

CAR-T細胞活化擴增：

CAR-T免疫療法

繼諾華和Kite公司兩款CAR-T細胞治療被FDA批準，2017年被媒體評為CAR-T療法的元年。

CAR T細胞免疫療法中，因為純化自體抗原呈遞細胞（APCs）用于T細胞活化需要好幾個額外步驟，增加獲得CAR T細胞產品強度和難度。因此研究者開發(fā)了另外一種更標準化、更具效率的T細胞活化方法，比如使用抗CD3/抗CD28單克隆抗體（anti-CD3/anti-CD28 monoclonal antibodies）。

而Dynabeads Human T-Activator CD3/CD28 這種微珠可以提供 T 細胞活化和擴增所需的原始和共刺激信號，通過使抗 CD3和抗 CD28 抗體與 Dynabeads 結合，更加速擴增。

推薦PeproTech抗CD3/抗CD28單克隆抗體產品

T細胞活化抗人CD3單克隆抗體（Functional，clone: OKT3）可以與TCR復合物結合，激活T細胞。SAFIRE(Sodium Azide Free Immensely Reduced Endotoxins) 類產品是BioGems品牌下的功能性抗體產品。

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 m 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.
