    Notes: Abstract: Ammonium chloride, widely used as an inhibitor of lysosomal protein degradation, was shown to inhibit strongly protein synthesis in neocortical slices from 10-day-old rats at a concentration of 10 mmol/L. Its usefulness in experiments with brain tissue is doubted. The possible meaning of the finding with respect to ammonia toxicity is briefly discussed.

    Notes: The method to localize and quantitate glycoproteins on polyacrylamide gels is based on the binding of Concanavalin A to the glycoproteins and the subsequent coupling of horseradish peroxidase to the glycoprotein - Concanavalin A complex. The complex is visualized by the oxidation of 3,3 -diaminobenzidine with horseradish perexidase - H2O2, forming a brownish stain at the gel surface. Various parameters are analyzed and a scheme for the optimal staining of macro and micro slab gels is given. The quantitative evaluation of the stained gels is demonstrated. The staining and quantitation of nitrocellulose transfers is also shown.

    Notes: Gonadal protein patterns were studied during development in the rat by two-dimensional micro-gel electrophoresis. Specific proteins were detected in both the male and the female sex at the morphologically indifferent state (two female- and one male-specific) and during differentiation. At the onset of gonadal differentiation (day 14) two additional sex-specific proteins were discovered in the male and two in the female. These proteins remained expressed during further development. One testicular protein was restricted to the cytosol of the tunica albuginea. The other one was absent from the tunica. In the female gonad, the two proteins were membrane-specific, one present in germ cells, the other in somatic cells. In the testis, one additional protein was discovered at postnatal day 1. Thus according to biochemical criteria there is no indifferent state of gonadal development. The testis and ovary express sex-specific genes both before and after the onset of gonadal differentiation.
