A pectic polysaccharide, lemnan LMC, was extracted from the callus of duckweed Lemna minor L. and was tested for adjuvant properties at oral administration with protein antigen. Mice were orally immunized thrice with weekly interval with free hen's egg lysozyme or lysozyme with LMC. Lemnan LMC was
The pectic polysaccharide named bergenan BC was obtained using extraction of the green leaves of Siberian tea Bergenia crassifolia (L.) Fritsch. by an aqueous ammonium oxalate. The polysaccharide obtained was proved to comprise mainly d-galacturonic acid, galactose, rhamnose, arabinose and glucose
Lemnan LM, apiogalacturonanic pectin of duckweed Lemna minor L. was tested for adjuvant properties following oral administration with protein antigen. Male Swiss mice were orally immunized thrice with weekly intervals with free OVA or OVA with lemnan (LM). Lemnan LM was shown to increase delayed
The ECTOPICALLY PARTING CELLS 1 (EPC1) gene encodes a putative retaining glycosyltransferase of the GT64 family, and epc1-1 mutant plants have a severely dwarfed phenotype. A new mutant allele of this gene, epc1-2, has been isolated. Reduced cell adhesion that has previously been reported for the
In the present study, the water-soluble polysaccharides of Radix Aconiti, Radix Aconiti Lateralis and Radix Aconiti Kusnezoffii, were extracted and fractionated into four fractions of each material. The FT-IR and chemical analyses indicated the water-soluble polysaccharides of the three materials
