Product Overview

CD4+ T cells are also known as helper T cells because they act on other cells of the immune system to promote various aspects of the immune response, including immunoglobulin isotype switching and affinity maturation of the antibody response, macrophage activation and enhanced activity of natural killer cells and cytotoxic T cells.

CD4+ T 细胞也被称为辅助 T 细胞，因为它们作用于免疫系统的其他细胞以促进免疫反应的各个方面，包括免疫球蛋白同种型转换和抗体反应的亲和力成熟、巨噬细胞活化和增强自然杀伤细胞的活性 和细胞毒性 T 细胞。

Cells You Can Count on to Perform

Lonza CD4+T Cells are isolated from peripheral blood of healthy donors using negative immunomagnetic separation.  Cryopreserved CD4+ T cells are guaranteed ≥ 90% pure for CD4+ T cells, as assessed by flow cytometry. They are guaranteed to contain ≥ 10 million viable cells per vial. HIV-1, hepatitis B and hepatitis C are not detected for all donors and/or cell lots. A Certificate of Analysis is provided for each cell lot purchased. Cells are available from multiple donors. Please contact Customer Service for details on available inventory and donor demographic characteristics (age, gender, and ethnicity).

Choices in Cell Type and Tissue Source

Hematopoietic and immune research requires cells from different donors and tissue sources. That’s why Lonza offers many different peripheral blood cell types. If you need different cell types from the same donor, you can either isolate from Lonza cryopreserved PBMCs or contact Customer Service to inquire about cells matched from the same donor. In addition, if you are interested in more naive T cells, unprocessed bone marrow, autologous bone marrow and whole blood from the same donor, bone marrow CD34+ cells, or cord blood CD34+ cells might be good solutions.
