Abstract: | A total of seven M-1 glycoprotein fractions were isolated from human colostrum whey and all showed L. bifidus var. Penn. growth promoting activities using well defined chemical medium. The growth promoting activity of these fractions was parallel to their total carbohydrate content. On the other hand, bovine colostrum M-1 glycoprotein had a relatively low growth promoting activity, whereas human serum orosomucoid had none. |
