Introduction:

CD4+ T cells play a central role in coordinating immune responses and are indispensable across multiple research fields, including immunotherapy, autoimmune disease research, and cancer immunology.

 

Product Overview:

Milecell MagSep™ CD4 MicroBeads, Human are superparamagnetic nanoparticles conjugated to monoclonal anti-human CD4 antibodies for in vitro positive selection or depletion of CD4+ cells from PBMCs, Leukopak, cord blood, bone marrow, and other single-cell suspensions.

 

Key Advantages:

• High specificity with minimal non-specific binding

• Excellent batch-to-batch consistency

• Preserves native cell viability and functionality

 

Cell Isolation Efficiency & Functional Validation:

1. Post-separation Viability, Recovery, and Purity

Figure 1. Fresh human peripheral blood mononuclear cells (PBMCs) derived from 3 donors served as the starting material to compare CD4+ T cell isolation performance between Milecell MagSep™ CD4 MicroBeads and competitor products under identical conditions, assessing post-separation viability, purity, and recovery .

Figure 2. The isolated CD4+ T cells were stimulated for 20 hours with an activation cocktail (PMA + Ionomycin). Cell culture supernatants were analyzed for IL-2 secretion by ELISA, while cells were assessed for surface marker expression (CD25/CD69) by flow cytometry. MileCell MagSep™ CD4  MicroBeads demonstrated comparable performance to competitor products in two critical functional parameters: CD25/CD69 expression levels, and IL-2 secretion capacity.
