| Abstract: | The lectin of Jack Fruit (Jacalin) was isolated and purified from the seeds of the Jack Fruit by precipitate of 40%~60% saturation ammonium sulfate and affinity chromatography on Gal-Sepharose 6B. Jacalin had an apparent molecular weight of about 58 200 and is composed of two kinds of subunits which had molecular weight 14 000 and 15 800, respectively. Isoelectric focusing on polyacrylamide gel showed that Jacalin gave a spread of components with calculated isoelectric point between 5.7 and 8.65. Jacalin is a glycoprotein by assay of Schiff''s stain. The two N-terminals are argenine and glynine. Jacalin could agglutinate red blood cells. |
