This is an affinity-purified rabbit antibody targeting mouse IgG, with a concentration exceeding 4.5 mg/ml. It's over 95% pure, as confirmed by SDS-PAGE. The antibody binds to heavy chains of mouse IgG and light chains of all mouse immunoglobulins, with no observed cross-reactivity to non-immunoglobulin mouse or human serum proteins. The rabbit serum used was sourced from healthy, US-origin animals under veterinary care.
