raffinose/sarcoma

Different fractions, isolated from the lichen Usnea fasciata, were analyzed by PC, TLC, and RP-HPLC. Analysis of the organic phases, mainly containing phenolics, revealed that usnic acid is the main product from secondary metabolites, whereas the polysaccharides isolichenin and raffinose are the

A dimeric lectin, composed of subunits with a molecular weight of 40 and 41 kDa, respectively, and demonstrating similarity in N-terminal sequence to each other and to Aleuria aurantia lectin, was isolated from fresh fruiting bodies of the edible mushroom Pleurotus ostreatus. The lectin was

Two toxic proteins were purified from the seeds of Abrus precatorius by DEAE-A 50 and Sepharose 4B chromatography. One of them does not bind on the Sepharose 4B column (Abrin-b) and the other (Abrin-a) is eluted with 0.2 M galactose. The amino acid compositions and tryptic maps of these two proteins

Three rhamnose-binding lectins were purified from the roe of Osmerus eperlanus mordax (olive rainbow smelt) by affinity chromatography and ion-exchange chromatography. The apparent molecular weights of Osmerus eperlanus mordax lectin (OML) -1, -2 and -3 were 25000, 32000 and 26000, respectively, on
