Proteins of the Seminal Fluid from the Vas deferens of Cocks: their Polymorphism and Relation to Serum Proteins
Proteins of the seminal fluid from the Vas deferens of cocks were studied by means of starch gel electrophoresis and immunoelectrophoresis. The presence of “transferrins” (TfSP) and “albumins” (AlbSP) was proved. Both proteins are immunologically related to the corresponding proteins of the blood serum. The existence of TfSP polymorphism was confirmed which is analogous to the polymorphism of serum transferrins. Heterogeneity of TfSP is discussed. AlbSP is polymorphic too, and the phenotypes correspond to the albumin phenotypes of the serum.
A number of other proteins, which call for more profound study, was detected in the seminal fluid of cocks.
