This study was aimed at isolation of pepsin-solubilised collagen (PSC) from Mackerel (Scomber japonicus) bone and skin in order to effectively valorise these abundant wastes. The yield of PSC (8.10%) from skin was considerably higher than that from bone (1.75%). Based on the protein patterns, both P...

values of 28 and 84 μg/mL, respectively. No colony was formed in MCF-7 cells in the presence of these nanoparticles as compared with control. Ag/AgCl-NPs induced apoptosis and generated ROS in MCF-7 cells. The expression level of FAS, FADD, and caspase-8 genes increased several folds with the decrea...

Chitinases are a group of enzymes that show differences in their molecular structure, substrate specificity, and catalytic mechanism and widely found in organisms like bacteria, yeasts, fungi, arthropods actinomycetes, plants and humans. A novel chitinase enzyme (designated as TDSC) was purified fro...

A Moringa oleifera seed lectin (MOSL) was purified by using chitin column with the molecular mass of 17±1kDa. The lectin agglutinated mouse, cow and human erythrocytes and the hemagglutination activity was inhibited by methyl-α-d-mannopyranoside, methyl-β-d-galactopyranoside, lactose and glucose. Th...

Abstract The importance of biogenic silver/silver chloride nanoparticles has become increasing day by day. In the present study, silver/silver chloride nanoparticles (Ag/AgCl‐NPs) were synthesized from Kaempferia rotunda tuberous rhizome extract to evaluate the antiproliferative activity against hum...

The concentration of natural radioactivity in rice is an important parameter for the determination of population exposure by the ingestion of natural radionuclides during habitual consumption of food. All types of food including rice contain a detectable amount of natural radioactivity which success...

A lectin was isolated from the tuberous rhizome of Keampferia rotunda by using different chromatographic methods with the molecular weight of 21±1kDa. The lectin contained highest percentage of leucine and lowest percentage of tryptophan residues as determined by LC-MS. The lectin agglutinated mice ...

A mixture of chitin-binding lectins from Tomato (Solanum lycopersicum) fruits, designated as Tomato chitin-binding lectins (TCLs), was isolated through affinity chromatography using an acetylated chitin column. Molecular weights of TCLs were determined to be 30 to 115 KDa which possessed mild toxici...

Vitis vinifera extract assisted silver nanoparticles (AgNPs) were biosynthesized that was confirmed primarily by color change and a sharp plasmon absorption band was found at 449 nm. Biosynthesized AgNPs shape was spherical and the particle size of 17 nm in average was confirmed by transmission elec...

An acid phosphatase has been isolated and purified from an extract of a germinating black gram seedling. The method was accomplished by gel filtration of a germinating black gram seedling crude extract on sephadex G-75 followed by ion exchange chromatography on DEAE cellulose. The acid phosphatase g...

Abstract In the present study, Ag/AgCl‐NPs were biosynthesised using Hypnea musciformis seaweed extract; NPs synthesis was confirmed by a change of colour and observation of a razor‐sharp peak at 424 nm by UV–visible spectroscopy. Synthesised nanoparticles were characterised by transmission electron...

A lectin with a molecular mass of 12 ± 1 kDa was isolated for the first time from Geodorum densiflorum (Lam.) rhizome (GDL). The lectin exhibited hemagglutination activity both in mice and human erythrocytes which was inhibited by 4-nitrophenyl-β-D-glucopyranoside among the tested 26 sugars. The lec...
