Human amniotic fluid fibronectin had different carbohydrate moieties from plasma fibronectin. Nearly 90% of glycopeptides released from amniotic fluid fibronectin was not bound by concanavalin A-Sepharose, whereas 75% of glycopeptides from plasma fibronectin was bound. Amniotic fluid fibronectin showed a significantly lower gelatin-binding affinity than plasma fibronectin at 25 degrees C. When the incubation temperature was lowered to 4 degrees C, no significant difference in this activity was found. Cell-attachment promoting activity of the two fibronectins was not significantly different.
人羊水纤连蛋白与血浆纤连蛋白具有不同的碳水化合物部分。从羊水纤连蛋白释放的糖肽中，近90%不与伴刀豆球蛋白A - 琼脂糖结合，而血浆纤连蛋白的糖肽中有75%与之结合。在25℃时，羊水纤连蛋白显示出比血浆纤连蛋白显著更低的明胶结合亲和力。当孵育温度降至4℃时，该活性未发现显著差异。两种纤连蛋白的细胞附着促进活性没有显著差异。
