A titer Sandwich ELISA using ab193185 as the detection antibody. The plate, coated with the capture antibody anti-human IgG, was loaded with different amounts of human IgG. A serial dilution of ab193185 was used as the detection antibody, followed with an alkaline phosphatase conjugated streptavidin.
ELISA of human immunoglobulins shows ab193185 reacts to both kappa and lambda light chains of human immunoglobulins. No cross reactivity with mouse, rat, or goat immunoglobulin light chain. The plate was coated with 50ng/well of different immunglobulins. 100 ng/mL or 20 ng/mL was used as the primary antibody. An alkaline phosphatase conjugated anti-rabbit IgG as the secondary antibody.
