Immunoelectrophoretical comparison of sera from Herring Gull (Larus argentatus) and Lesser Black-backed Gull (Larus fuscus) (Aves)

Sera from Herring Gull (Larus argentatus) and Lesser Black-backed Gull (Larus fuscus) were compared by crossed immunoelectrophoresis with intermediated gel technique. No differences in antigenicity were revealed with respect to the reactions of serum proteins with their homologous and heterologous antisera produced in rabbits.
