Product Overview

CD4+ CD8+ T-cells 

Product DescriptionHuman T cells are lymphocytes characterized by the expression of CD3 on the cell surface. These cells play a key role in cell-mediated immunity, derive from the bone marrow and migrate to the thymus to undergo maturation. There are several different subsets of T cells, including helper T cells, cytotoxic T cells, regulatory T cells, and natural killer T cells. T cells are a mixture of CD4+ and CD8+ T cell subtypes with a smaller portion of gamma/delta T cells.  

Tissue Source: Leukopak 

Size: 10E6, 25E6, 50E6

Cell Isolation: Cell isolation is performed on-site at our Gift of Life Center for Cell and Gene Therapy. CD4+CD8+ T Cells are positively isolated from leukopaks. Blood cells expressing CD4 and CD8 maker are enriched from a leukopak using immunomagnetic beads that label the target cells, resulting in a purified population of CD4+CD8+ (CD3+) T cells. Viability and purity post isolation are assessed by flow cytometry. 

Cryopreservation and Storage: Cell products contain 10% DMSO to preserve cell viability and reduce loss during freezing. Cryopreserved products are stored in LN2 tanks and shipped on dry ice.  

Thawing Instructions: Refer to our thawing protocol
