Abstract
Human serum contains an ultrafiltrable factor which stimulates the somatomedin activity measured by 35SO4 incorporation into pelvic cartilage of chick embryo, this ultrafiltrable factor activates native serum somatomedin or partially purified somatomedin. The molecular weight determined by fractionated ultrafiltration or chromatography on Biogel P2 is about 350-500 daltons.
摘要
人血清中含有一种可超滤因子，该因子可刺激通过将³⁵SO₄掺入鸡胚盆腔软骨来测定的生长调节素活性，这种可超滤因子可激活天然血清生长调节素或部分纯化的生长调节素。通过分级超滤或在Biogel P2上进行色谱法测定的分子量约为350 - 500道尔顿。
