Dynabeads免疫磁珠特點(diǎn)

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(xì)胞活化無(wú)需滋養(yǎng)層細(xì)胞

• Activated cells that retain in vivo-like function

活化細(xì)胞功能同體內(nèi)培養(yǎng)

• Maximum reproducibility without contamination by soluble antibodies or mitogens

zui高可重復(fù)性，沒有抗體溶解和絲裂原污染。

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

T細(xì)胞擴(kuò)增100-1000倍

CAR-T免疫療法

繼諾華和Kite公司兩款CAR-T細(xì)胞治療被FDA批準(zhǔn)，2017年被媒體評(píng)為CAR-T療法的元年。

CAR T細(xì)胞免疫療法中，因?yàn)榧兓泽w抗原呈遞細(xì)胞（APCs）用于T細(xì)胞活化需要好幾個(gè)額外步驟，增加獲得CAR T細(xì)胞產(chǎn)品強(qiáng)度和難度。因此研究者開發(fā)了另外一種更標(biāo)準(zhǔn)化、更具效率的T細(xì)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(xì)胞活化和擴(kuò)增所需的原始和共刺激信號(hào)，通過(guò)使抗 CD3和抗 CD28 抗體與 Dynabeads® 結(jié)合，更加速擴(kuò)增。

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.
