[Relationship between the anticoagulant activity of sulfated plant polysaccharides and the area of their precipitation with polycations during biospecific electrophoresis].
Polyanions (in an amount within 1.5 - 6.0 mg), including cellulose sulfates (excreted from Gossipium hirsutum L., molecular weight 22.0 kDa, degree of sulfation within 0.8 - 1.8), inulin sulfates (excreted from Helianthus tuberosus, molecular weight 8.0 kDa, degree of sulfation within 0.6 - 1.6), pectin sulfates (excreted from Abies sibirica L., molecular weight 24.0 kDa, degree of sulfation within 0.8 - 1.1), give rise to peaks of precipitation with polycations of protamine sulfate. Only cellulose sulfates (in amount within 0.38 - 6.00 mg) give the peaks of precipitation with chitosan polycations (molecular weight 10 kDa, degree of deacetylation 85%) during horizontal biospecific electrophoresis. The height of the peak of precipitation with protamin sulfate was found to grow with increasing antithrombin activity of cellulose sulfates and pectin sulfate (for polyanions in an amount within 1.5 - 6 mg). The size of the area of precipitation with chitosan was found to decrease with increasing antithrombin activity of cellulose sulfates.

Polysaccharides with sulfate groups are human T cell mitogens and murine polyclonal B cell activators (PBAs) II. Cellulose sulfate and dextran sulfate with two different lower molecular weights.
In our previous paper, we reported that various types of carrageenan, dextran sulfate and fucoidan, which are sulfated homopolysaccharides with high molecular weights, were human T cell mitogens and murine polyclonal B cell activators (PBAs) and that heparin, a sulfated heteropolysaccharide, was a very weak human mitogen and mouse PBA. Here we used cellulose sulfate (Mr 7-9 X 10(3], dextran sulfate with two different low molecular weights (Mr 5 X 10(3) and 8 X 10(3], two different condroitin sulfates (Mr 3.5 X 10(4], polyvinyl sulfate and polygalacturonic acid to investigate mitogenic activities of polysaccharides in detail. The following results were obtained. Low-molecular-weight sulfated homopolysaccharides, dextran sulfate and cellulose sulfate, were very weak or not human T cell mitogens. However, they were better murine PBAs. Sulfated heteropolysaccharides, chondroitin 4-sulfate and chondroitin 6-sulfate, hardly induced mitogenic changes in human T cells and mouse B cells, even though the molecular weight of these substances was more than 1 X 10(4). There were no other polymers examined so far which activated both human T cells and murine B cells. The relationship among molecular size, sulfate groups and lymphocyte activation is discussed in detail.
