Anti-Gal-1 antibodies isolated from an Ipi-Bev-treated patient abrogate Gal-1 binding to CD45. Anti-Gal-1 antibodies were affinity purified from plasma. Biotinylated HAS-Gal-1 (250 ng/ml) was incubated with a commercial anti-Gal-1 polyclonal antibody (Gal-1 Ab) or control antibody (10 μg/ml), enriched endogenous Gal-1 antibodies (Gal-1 Ig) or normal human IgG (1.98 μg/ml) prior to incubation with coated CD45. The binding of HAS-Gal-1 to CD45 was detected with streptavidin-HRP. Sucrose and lactose were added to the reaction at 5 mM. Data are presented as Mean ± SD of 3 experiments.
