Biochemical Characterization of Lectin Purified from Kidney Bean Seedling

강낭콩 유식물로부터 분리한 Lectin의 생화학적 특성

  • Published : 2007.02.28


We have studied biochemical characterization of lectin purified from kidney bean seedling through PBS extraction, $(NH_4)_2SO_4$ precipitation, and Sephadex G-100 affinity chromatography. The lectin was agglutinated by rabbit erythrocytes. This lectin analyzed by SDS-PAGE is a tetramer composed of two subunits with molecular weights of 46 and 44 kDa. The optimal temperature and thermal stability of the lectin was 30$^{\circ}C$ and 40-80$^{\circ}C$, respectively. The maximal pH of this lectin was pH 8.2.
