title: Absence of a 23 kd protein in testes of testicular feminization rat.
abstract: Cryptorchid testes of testicular feminization rats are very low in zinc in spite of normal zinc status of the animals. Analysis of the cytosol of the cryptorchid testes by gel permeation chromatography showed decreased zinc binding by proteins eluted at fractions corresponding to 30,000 dalton. Further analysis by sodium dodecylsulphate polyacrylamide gel electrophoresis indicated the absence of a protein with molecular weight of 23,000.
