Human Anti-IL2 Recombinant Antibody (clone F5111.2)

Figure 1 Antibody F5111.2 inhibits upregulation of IL-2-induced proteins in CD8+ T cells but not Tregs in vitro.

Dose response of CD25 and FoxP3 expression on Treg, Tconv and CD8 cells following expansion of human PBMCs in the presence of hIL-2 (5 ng/ml)–F5111.2 complexes for five days. Representative results from one of five experiments are shown.

Figure 1 Anti-IL2 Recombinant Antibody (PABC-506) in ELISA

ELISA analysis of PABC-506 was performed by coating with human IL2 protein (His tag). Then blocked with BSA and incubated with PABC-506. The HRP-conjugated goat anti-IgG was used as a secondary antibody (1: 2000). Detection was performed using TMB substrate and stopped with sulfuric acid. The absorbances were read on a spectrophotometer at 450 nm.

Figure 2 Anti-IL2 Recombinant Antibody (PABC-506) in WB

Western blot analysis of PABC-506 was performed by loading human IL2 protein onto a 12% Tris-HCl polyacrylamide gel. Proteins were transferred to a CN membrane and blocked with 5% skim milk for at least one hour. Membranes were probed with PABC-506 and a HRP goat anti-IgG (H+L) was used as the secondary antibody (1: 3000). Chemiluminescent detection was performed.
