GMP version GMP-MBS001 is now available for seamless transition.
ProductSizeAmount
Human T cell Activation/Expansion CD3/CD28 Beads, premium grade DMF Filed2.5 mg2.5 × 10⁷ beads
10 mg1.0 × 10⁸ beads
  • Background
    Human T cell Activation/Expansion CD3/CD28 Beads, premium grade DMF Filed are uniform 5.5 μm of magnetic beads coated with an optimized mixture of monoclonal antibodies against the CD3 and CD28. The CD3 antibody is specific for the epsilon chain of human CD3, which is considered to be a subunit of the TCR complex. The CD28 antibody is specific for the human CD28 co-stimulatory molecule, which is the receptor for CD80 (B7-1) and CD86 (B7-2). Both antibodies are mouse anti-human IgGs coupled to the same bead, mimicking in vivo stimulation by APCs.
  • Application
    ActiveMax® Human T cell Activation/Expansion CD3/CD28 Beads, premium grade DMF Filed is intended for the in vitro isolation, stimulation and expansion of purified T cell populations of, for example, CD3+T cells, CD4+ T cells, CD8+ T cells or human PBMC in early preclinical stage.

 CD3 & CD28 TYPICAL DATA

Fig.1. Activation of the purified human T Cells.The human T cells were stimulated with ActiveMax® Human T cell Activation/Expansion CD3/CD28 Beads, premium grade(Cat. No. MBS-C001) for 24hrs, and the activation was assessed by measuring expression of both activation markers CD25 and CD69 expression on the T cells surface by stanning with PE labeled anti-human CD25 antibody and FITC labeled anti-human CD69 antibody respectively (QC tested).

 CD3 & CD28 TYPICAL DATA

Fig.2. Purified human T Cells expansion.The human T cells were labeled with carboxy fluorescein succinimidyl ester (CFSE) and stimulated with ActiveMax® Human T cell Activation/Expansion CD3/CD28 Beads, premium grade(Cat. No. MBS-C001), and then the proliferation of the T cells was assessed with CFSE dilution assay by flow cytometry on day 5 after stimulation (QC tested).

Stability
 CD3 & CD28 STABILITY

Activation of the purified human T Cells. The purified human T cells were activated using Human T cell Activation/Expansion CD3/CD28 Beads, (ACRO, Cat. No. GMP-MBS001/MBS-C001) respectively for 24 hours with CTS Optimizer Medium. Cells were fluorescently stained using PE labeled anti-human CD25 antibody and labeled FITC anti-human CD69 antibody and analyzed by flow cytometry.

 CD3 & CD28 STABILITY

Expansion of the human CD3+T cells. Human T cells using ACROBiosystems CD3/CD28 Beads (ACRO, Cat. No. GMP-MBS001/MBS-C001) were expanded under two different medium, respectively. Expansion was performed for two weeks, showing that ACROBiosystems’ GMP and RUO beads showing similar proliferative abilities.
