本文报告小牛胸腺肽类因子各组分的生物化学性质。藉Sephadex G-15可将肽类与粗制品中的核苷酸类物质分开,然后经过DEAE-Sephadex A-25,Sephadex G-10及两相纸层析,有生物活性的肽类可纯化得到单一肽类分子,估计分子量在1000道尔顿左右。
This article reports on the biochemical properties of calf thymosin factor components. Sephadex G-15 can separate the peptides from the nucleotides in the crude product, and then through DEAE-Sephadex A-25, Sephadex G-10 and two-phase paper chromatography, biologically active peptides can be purified. A single peptide molecule is estimated to have a molecular weight of about 1000 Daltons.
