PurityImmunogen affinity purified
Purification notesThis antibody was isolated by affinity chromatography using antigen coupled to agarose beads. F(ab')2 fragment were generated using a pepsin digestion. Fc fragments and whole IgG molecules have been removed. Fragments were conjugated to Phycoerythrin.
By immunoelectrophoresis and ELISA this antibody reacts specifically with human IgG. Cross reactivity with IgA and IgM is negligible. No antibody was detected against non-immunoglobulin serum proteins. Less than 1% cross reactivity to mouse and rat IgG was detected. This antibody may cross react with IgG from other species.

Flow Cytometry - Goat F(ab')2 Anti-Human IgG - Fc (PE), pre-adsorbed (ab98596)
CHO cell line expressing membrane bound human TNFα (stable transfectants) was incubated with 10 μg/ml Remicade (anti-human TNFa monoclonal antibody) for 1 h in 4°C. The unbound antibody was washed off by centrifugation (300x g for 5 min) and binding of remicade was detected with PE Goat F(ab)2 anti-hIgG Fc (ab98596) – 1:100 (5 µg/ml), 30 min incubation in 4°C. The cells were washed twice in FACS buffer (2.5% BSA, 0.1% sodium azide in dPBS), before flow cytometric analysis.
PE goat F(ab)2 anti-hIgG detected binding of remicade to TNFα CHO cell line giving strong positive signal, however there was some non-specific binding to the cells alone. Further optimisation of the reagent concentration and washing procedure should improve the background signal.
