High-performance gel filtration patterns of venoms from three species of wasps of the genus Polybia (hymenoptera, vespidae).
(1996-01-01)
The profiles of high-performance gel filtration of venoms from Polybia paulista, Polybia ignobilis and Polybia occidentalis occidentalis showed 13 peaks distributed among the three species. These profiles presented ...

Purification and characterization of two β-glucosidases from the thermophilic fungus Thermoascus aurantiacus
(2002-12-01)
β-Glucosidase from the fungus Thermoascus aurantiacus grown on semi-solid fermentation medium (using ground corncob as substrate) was partially purified in 5 steps-ultrafiltration, ethanol precipitation, gel filtration and ...
Proteolytic activity of africanized honeybee (Apis mellifera: hymenoptera, apidae) venom
(Centro de Estudos de Venenos e Animais Peçonhentos - CEVAP, Universidade Estadual Paulista - UNESP, 2000)
Some properties of a Africanized honeybee venom proteases were determined by enzymatic assays in solution, electrophoresis in SDS-PAGE, and gel filtration. Bee venom extracts were obtained by reservoir disruption, selective ...
Rhizoctonia solani fucomannogalactan: Chemical characterization and antiproliferative activity
(2018-08-01)
A fucomannogalactan from Rhizoctonia solani biomass was obtained after hot aqueous extraction and purified by freeze-thaw cycles and gel filtration chromatography on Sepharose CL-6B. The polysaccharide was homogeneous after ...
Changes in protein fractions, trypsin inhibitor and proteolytic activity in the cotyledons of germinating chickpea
(2001-09-01)
The chickpea seed germination was carried out in 6 days. During the period it was observed a little variation on total nitrogen contents, however the non protein nitrogen was double. A decrease of 19.1 and 20.6% in relation ...
