Product Overview

CD4+ Helper T-cells 

Product Description: CD4+ helper cells are a type of T cell that play a crucial role in the immune system. They can trigger and coordinate the immune response against infection and disease by activating other immune cells such as B cells, macrophages and cytotoxic CD8+ cells.

Size: 10E6 and 25E6

Tissue Source: Leukopak

Cell Isolation: Cell isolation is performed on-site at our Gift of Life Center for Cell and Gene Therapy. CD4+ helper T cells are positively isolated from leukopaks. Blood cells expressing CD4 maker are enriched from a leukopak using immunomagnetic beads that label the target cells, resulting in a purified CD4+ helper T cell population. 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
