[iba] Controlling your T cell expansion

관리자 2019.06.15 11:27 조회 74

T cell expansion


The in vitro generation of a large number of functional T cells is important for basic research as well as for therapeutic approaches, where consistent quality and purity of expanded T cells play an essential role. Commonly magentic beads carrying αCD3 and αCD28 monoclonal antibodies are used for the activation of the T cells. Depending on the proliferation of the cells, with this approach the cells need to be continuously split.

In contrast, CD3/CD28 Streptamers® are non-magnetic soluble protein complexes generated by multimerization of anti-CD3 and anti-CD28 Fab-Streps with a Strep-Tactin® multimer. They are completely reversible reagents and can therefore be removed from the cells at any time by adding biotin. Thus, this technology enables the complete control of the expansion process and the cell receptors are available for further staining experiments.

CD3/CD28 Streptamers® for simple and effective cell activation

Polyclonal expansion of T cells can be easily achieved via non-magnetic soluble protein complexes generated by multimerization of αCD3- and αCD28 Fab-Streptamers® with a Strep-Tactin® multimer.
