Normal nurse shark and lemon shark sera contain ∼17S and 7S immunoglobulins with anti-dinitrophenyl activity. Specifically purified 17S “anti-DNP” precipitated in gels with DNP-BSA conjugates, bound to DNP-immunoadsorbents (∼60%) but did not give detectable binding by equilibrium dialysis. The 7S “anti-DNP” did not precipitate in gels, nor did it bind radiolabeled hapten and only about 25% bound to DNP-immunoadsorbents. Of special interest was the observation that specifically purified 17S… CONTINUE READING
