A precipitin for human serum proteins as released into the environment by stressed bait shrimp, Penaeus duorarum.
1. A precipitin for human serum proteins is released into the environment by stressed bait shrimp, Penaeus duorarum. 2. Two-dimensional crossed immunoelectrophoresis revealed that the precipitin reacts (a) primarily with proteins belonging to the major group, alpha-1 globulin; and (b) with more proteins than a standard mammalian antiserum. 3. This study extends the variety of species known to liberate precipitins and suggests this response may be widespread among invertebrates. 4. The precipitins are easily collected in saline solution and, by virtue of their unique specificities, are potentially useful in diagnostic testing.
