不同批号人转移因子(TF-h)和猪转移因子;(TF-p)在聚丙烯酰胺凝胶电泳上均出现一条深色带,其电泳位置较为接近。此外,还可看到电泳位置基本相同的二条浅染色带,提示二种TF主要组成分子所带电荷及分子量都比较接近,这些不同分子带与转移因子生物活性的关系,有待进一步研究确定。 Different TF-h and TF-TF (TF-p) showed a dark band on polyacrylamide gel electrophoresis, and their electrophoresis positions were close. In addition, two light-stained bands with the same electrophoresis position can be seen, suggesting that the charges and molecular weights of the two main TF molecules are relatively close. The relationship between these different molecular bands and the biological activity of the transfer factor needs to be further studied and confirmed.
