Human Immune Cells AND Hematopoietic Cells derived from Peripheral Blood (Peripheral Blood CD4+ Helper T - Untouched) within the Blood system.\u003c\/p\u003e\n\u003cp\u003eThe CD4+ T cells, also known as T helper cells (T h cells), are a type of T cells that play an important role in the immune system, particularly in the adaptive immune system [1] . CD4+ T cells can regulate immune response through different cytokines secreted [2] . They are essential in B cell antibody class switching, in the activation and growth of cytotoxic T cells, and in maximizing bactericidal activity of phagocytes such as macrophages. Considering the diverse and important role CD4+ T cells play in the immune system, it is not surprising that these cells often influence the immune response against disease. CD4+ T cells have been involved in hypersensitivity and as the main target cells of HIV pathogenesis. iXCells Biotechnologies offers CD4+ T Cells isolated from normal human peripheral blood mononuclear cells (PBMCs) using negative immunomagnetic selection. \u0026gt; 90% of the cells are CD4+ as showed by flow cytometric analysis.\u003c\/p\u003e\n\u003ch2\u003eKey elements and design rationale\u003c\/h2\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCell identity:\u003c\/strong\u003e Immune Cells AND Hematopoietic Cells (Primary Cells)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSource context:\u003c\/strong\u003e Peripheral Blood; Peripheral Blood CD4+ Helper T - Untouched; Blood\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBiosafety level:\u003c\/strong\u003e BSL-2 (follow your institution’s biosafety program and local regulations)\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eProduct-specific elements (such as tissue source, donor background, and cell classification) help frame how results should be interpreted across assays and experimental conditions.\u003c\/p\u003e\n\u003ch2\u003eBiological background\u003c\/h2\u003e\n\u003cp\u003eCells originating from the Blood system are commonly studied to understand tissue-specific physiology, signaling, and responses to perturbations in controlled in vitro settings.\u003c\/p\u003e\u003cp\u003eAcross primary and specialty cell models, experimental outcomes can be influenced by donor heterogeneity, passage history, confluence, and media composition.
