Product Description

The Rapid-Act T Cell Activation Kit (Mouse, Anti-CD3/CD28) provides the necessary reagents for easy, single-step induction of mouse T cell activation and proliferation. The included Synthetic Immune Synapse particles pre-cluster the CD3 and CD28 antibodies for thorough T cell activation, and are small enough to minimize cell clumping. Because the reagents are added to the cells in a single step, the kit enables accurate time course studies for short-term T cell stimulation. The kit can also be used for longer-term T cell proliferation and exhaustion assays. No modification or removal is necessary prior to subsequent analysis by flow cytometry.

Background

T cells are activated by signaling through ITAM (immunoreceptor tyrosine-based activation motif)-containing CD3 signaling chains that associate with the T cell receptor (1). Co-stimulation through CD28 on T cells provides an additional signal required for effective T cell activation (2). Antibody-based binding and aggregation of CD3 and CD28 proteins simulates the engagement of a T cell with an antigen presenting cell, and results in T cell activation.

Species Reactivity

Species reactivity is determined by testing in at least one approved application (e.g., western blot).
