豌豆凝集素(Pisum sativum agglutinin,PSA)是从豌豆中提纯的一种植物凝集素。它与细胞表面受体及与可溶性糖蛋白和糖脂间的反应性、使其成为研究细胞生物学特性,尤其是研究糖类复合物的常用生化试剂之一。新近我们发现,应用
Pisum sativum agglutinin (PSA) is a phytohemagglutinin purified from pea. Its reactivity with cell surface receptors and with soluble glycoproteins and glycolipids has made it one of the biochemical reagents commonly used to study cell biology, especially carbohydrate complexes. Recently we found that application
