Sheep polyclonal antibody against human immunoglobulins IgG, IgM and IgA, affinity-purified, 1 mg. Broad pan-immunoglobulin reactivity for total-antibody detection across all three major human isotypes — a versatile secondary/detection reagent. For the rabbit pan-Ig equivalent see cat. 172 (rabbit anti-human IgG + IgM + IgA); for isotype-specific detection use the goat cat. 454 (anti-human IgG) or goat cat. 321 (anti-human IgM).
