Abstract

Antibody preparation and identification of the Cashmere goat c-kit protein in the testes

The c-kit protein plays a major role in the regulation of germ cell development. Its expression and distribution in rodent testes have been widely reported. However, research regarding c-kit expression in domestic animals is scarce, and the expression pattern and distribution of c-kit in germ cells have not been clearly defined. In this study, a specific antigenic region for goat c-kit was designed, and a c-kit polyclonal antibody was prepared. This antibody was then applied in a study evaluating c-kit expression in Cashmere goat tissues. A Western blot analysis showed that three forms of c-kit were expressed in goat testes: precursor, mature, and soluble c-kit. Fluorescent immunohistochemical analyses showed that c-kit was primarily expressed in the spermatogonia and spermatocytes of goat testes. These results not only clarify the expression and localization of c-kit in the goat testis, but also accelerate further research regarding the function of c-kit in goat spermatogenesis.
