Recombinant Mouse Antibody binds selectively to Mouse CD28, expressed in HPB-M.
Figure 1 The CD28 superagonist ANC28.1 induces polyclonal T cell activation in vitro and leads to ZAP70 independent phosphorylation of LAT and PLCc1.
5x10⁴ freshly prepared human T cells per well were seeded in 96-well plates and treated with the indicated combinations of antibodies or were incubated in medium as a control.

Figure 2 Induction of sustained calcium flux by human CD28 superagonistic antibody ANC28.1.
1x10⁶ freshly prepared Indo-1 loaded human T cells were stimulated with either a 1:50 v/v dilution of ascites fluid of CD3 mAb MEM92 (orange triangle), 10 mg/ml conventional CD28 mAb (CD28.2; blue triangle) followed by crosslinking with 20 mg/ml polyclonal goat anti-mouse antiserum (black triangle) or 10 mg/ml ANC28.1 (red triangle) followed by crosslinking with 20 mg/ml polyclonal goat anti-mouse antiserum (black triangle).

Figure 3 Sustained calcium flux, T cell proliferation, and T cell signaling upon TGN1412 treatment.
5x10⁴ freshly prepared human T-cells/96-well were stimulated with the indicated concentrations of ANC28.1 or TGN1412 or were left untreated as a control. For crosslinking of ANC28.1, a polyclonal goat anti-mouse antiserum was used and crosslinking of TGN1412 was performed.
