TAB-064LC is a superagonistic monoclonal antibody (mAb) capable of fully activating T-cells by cross-linking CD28 molecules, even without signal 1, which sets it apart from conventional anti-CD28 mAbs. TAB-064LC exhibits a binding affinity to human CD28, with an EC50 value of 4.4 nM. TAB-064LC exhibits a binding affinity to human T cells, with EC50 values measured at 2.5 nM.
Figure 1 Anti-CD28 Antibody (TAB-064LC) in ELISA
ELISA analysis of TAB-064LC was performed by coating with Recombinant Human CD28 Protein (11524-HCCH). Then blocked with BSA, and incubated with Anti-Human CD28 Antibody (TAB-064LC). The HRP-conjugated goat anti-human IgG as a secondary antibody. Detection was performed using TMB substrate and stopped with sulfuric acid. The absorbances were read on a spectrophotometer at 450 nm.
Figure 2 Anti-CD28 Antibody (TAB-064LC) in WB
Western blot analysis of TAB-064LC was performed by loading Recombinant Human CD28 Protein (11524-HCCH) onto a 12% Tris-HCl polyacrylamide gel.
Lane 1: Non-Reducing Antigen (0.5 μg)
Lane 2: Reducing Antigen (0.5 μg)
Figure 3 Anti-Human CD28 Recombinant Antibody (TAB-064LC), Fc Silenced, in SDS-PAGE
SDS-PAGE analysis of TAB-064LC, Fc silenced, in non-reduced (Lane 1) and reduced (Lane 2) conditions. Gel stained for 30 minutes with Coomassie Blue. As a result, different β-mercaptoethanol-reduced proteins (Heavy chain and Light chain) migrate as about 50 kDa and 25 kDa, respectively.
The purity of TAB-064LC-FcS was greater than 95% as determined by SDS-PAGE.
