PharmaOnco™ Human CD4⁺//CD45RA⁺//CD25^- Naive Helper T Cells

Creative Biolabs offers Human CD4⁺//CD45RA⁺//CD25^- Naive Helper T Cells for a wide variety of immunology-based assays.

Human CD4+CD45RA+CD25- naive helper T cells are a subset of T cells that are characterized by the expression of the cell surface markers CD4, CD45RA, and absence of CD25. CD4+CD45RA+CD25- naive helper T cells are an important component of the immune system and play a key role in mounting effective immune responses against pathogens.

CD4+ cells, also known as T-helper cells, are a type of white blood cell that play a critical role in the functioning of the immune system. These cells are responsible for coordinating the immune response by activating and directing other immune cells to defend against pathogens such as bacteria, viruses, and other foreign invaders. CD4+ cells also play a key role in adaptive immunity, a specific immune response that develops after exposure to a pathogen to provide long-lasting protection against future infections. In individuals with human immunodeficiency virus (HIV), the virus specifically targets and infects CD4+ cells, leading to a weakening of the immune system and increased susceptibility to infections.

Creative Biolabs provides sterility testing in accordance with USP and EP regulations. All of our sterility testing is performed in an isolator or clean room environments. The cell line has been screened using the membrane filtration testing methods to confirm the absence of aerobic, anaerobic and fungi microorganisms.

We perform cell genetic stability studies under ICH guidelines. We can provide guidance on the appropriate testing program upon your requirements.

All cells were collected under Institutional Review Board (IRB)-approved consent forms and protocols.
