CD8 MicroBeads, human

Product Details

Overview

CD8 MicroBeads were developed for the positive selection or depletion of human cytotoxic CD8⁺ T cells from different cell sources. The most commonly used cell sources are peripheral blood and cord blood. In addition, cytotoxic T cells have also been isolated from lymph nodes, thymus, skin biopsies¹, and spleen.

Columns

For positive selection: MS, LS, XS, or autoMACS^® Columns. For depletion: LD, D, or autoMACS Columns.

Downstream Application

Isolation or depletion of CD8⁺ cytotoxic T cells is performed in many different research fields such as infectious diseases, autoimmune diseases, allergy, and asthma, as well as tumor immunology.

Cytotoxic T cells isolated by MACS^® Technology remain viable and functional. Therefore, they can be used for further functional studies, such as proliferation assays^2,9 ａnd cytotoxicity assays^2,3, but also for the analysis of in vitro cytokine production⁴. CD8 MicroBeads have also been used for the depletion of CD8⁺ T cells from human PBMCs for immune reconstitution experiments in SCID mice.⁵

In combination with CD4 MultiSort MicroBeads, CD8 MicroBeads have been used for the isolation of CD4⁺CD8⁺ double-positive thymocytes.⁸

Other examples include various studies on viral infections, e.g.,in vitro infections of CD8⁺ cells with HIV⁶, or monitoring of immune abnormalities in children of HIV-infected mothers⁷.
