Soluble fibronectin of human plasma was specifically dissociated at neutral pH from gelatin-agarose by several cationic amino compounds, notably the polyamines spermine, spermidine and putrescine, the basic amino acid arginine, and amino sugars. The neutral and acidic amino acids and the N-acetylated derivatives of amino sugars tested were ineffective. Gel-filtration experiments demonstrated that [14C]spermidine bound to fibronectin but not to gelatin.
人血浆中的可溶性纤连蛋白在中性pH条件下可被几种阳离子氨基化合物从明胶琼脂糖上特异性解离,特别是多胺类的精胺、亚精胺和腐胺、碱性氨基酸精氨酸以及氨基糖。所测试的中性和酸性氨基酸以及氨基糖的N - 乙酰化衍生物均无效。凝胶过滤实验表明,[14C]亚精胺与纤连蛋白结合,但不与明胶结合。
