Human tryptophan-rich prealbumin has been isolated from serum and its homogeneity evaluated by immunoelectrophoresis and polyacrylamide-gel electrophoresis. The green fluorescence of the protein when exposed to ultraviolet light was shown to be due to the presence of vitamin A. It is suggested that trytophanrich prealbumin represents the hitherto unknown specific transport protein for vitamin A.
已从血清中分离出富含色氨酸的人前白蛋白,并通过免疫电泳和聚丙烯酰胺凝胶电泳评估其均一性。该蛋白质在紫外光照射下发出的绿色荧光表明其含有维生素A。有人提出,富含色氨酸的前白蛋白代表了迄今为止未知的维生素A特异性转运蛋白。
