Abstract
Two distinct factors which stimulate the recovery of plaque-forming cells in the vitro immune response have been found in human serum. One acts in the presence of fetuin and the other augments the recovery of plaque-forming cells in its absence. The molecular weight of the former is higher than 1 X 10(5). The two factors could be separated from each other by ammonium sulphate fractionation. Large differences were found in the amount of these factors in sera obtained from different human donors.
摘要
在人血清中发现了两种不同的因子，它们可刺激体外免疫反应中噬斑形成细胞的恢复。一种因子在胎球蛋白存在时起作用，另一种因子在胎球蛋白不存在时增强噬斑形成细胞的恢复。前者的分子量高于1×10⁵。这两种因子可通过硫酸铵分级分离彼此分开。从不同人类供体获得的血清中，这些因子的含量存在很大差异。
