Chitin-binding antifungal protein from <Emphasis Type="Italic">Ficus carica</Emphasis> latex

A low-molecular-weight protein with antifungal activity was isolated from freshly collected latex of the Inzhir tree (Ficus carica L.) by successive affinity chromatography over chitin, cation-exchange chromatography over SP-Sephadex C-50, and reversed-phase HPLC. The molecular weight of 6481 and the partial N-terminus sequence of the protein were determined (MALDI-TOFMS). __________ Translated from Khimiya Prirodnykh Soedinenii, No. 2, pp. 171–173, March–April, 2008.

Solid-Phase Colorimetric Method for the Quantification of Fucoidan

We described the simple, selective, and rapid method for determination of fucoidans using methylene blue staining of sulfated polysaccharides, immobilized into filter paper and consequent optic density (at A ₆₆₃?nm) measurement of the eluted dye from filter paper. This solid-phase method allows selective determination of 1?C20???g fucoidan in presence of potentially interfering compounds (alginic acid, DNA, salts, proteins, and detergents). Further, we demonstrated the alternative way of using image processing software for fucoidan quantification without extraction of methylene blue dye from stained spots of fucoidan?Cdye complex.
