支持细胞合成并分泌一种铜蓝蛋白样蛋白(睾丸铜蓝蛋白),在免疫学上与血清铜蓝蛋白相似。纯化大鼠血清血浆铜蓝蛋白,并制备纯化蛋白的抗血清,其特异性免疫沉淀来自大鼠血清的130,000道尔顿蛋白。发现该血浆铜蓝蛋白抗血清也免疫沉淀由Sertoli细胞合成和分泌的130,000道尔顿蛋白。蛋白酶抑制剂,苯甲基磺酰氟(PMSF)的存在下,需要在免疫沉淀过程中,以防止睾丸铜蓝蛋白的蛋白水解降解。用大鼠血清蛋白质的抗血清免疫沉淀支持细胞分泌的蛋白质,发现沉淀两种蛋白质,睾丸铜蓝蛋白和睾丸转铁蛋白。
Sertoli cells synthesize and secrete a ceruloplasmin-like protein (testicular ceruloplasmin) that is immunologically similar to serum ceruloplasmin. Rat serum ceruloplasmin was purified and an antiserum was produced to the purified protein which specifically immunoprecipitated a 130,000 dalton protein from rat serum. This ceruloplasmin antiserum was found to also immunoprecipitate a 130,000 dalton protein synthesized and secreted by Sertoli cells. The presence of a protease inhibitor, phenylmethylsulfonyl fluoride (PMSF), was required during the immunoprecipitation procedure to prevent the proteolytic degradation of testicular ceruloplasmin. Immunoprecipitation of proteins secreted by Sertoli cells with an antiserum to rat serum proteins was found to precipitate two proteins, testicular ceruloplasmin and testicular transferrin.
