in this study, we present changes of peroxidase (e. c. 1.11.1. 7) activities in the root of brassica napus var. okapi during rosette stage until ripening of the fruits. peroxidase activity was determined seasonally over an eight month period. results showed that total peroxidase activity in the root was highest in mid june and the lowest activities were observed from time of winter dormancy unt...

hbs vaccines were prepared by three different methods: 1) heat inactivation (krugman, et.al 1971)2) ammonium sulphate precipitation followed by column chromatography (sephadex g-200) 3) peg-6000 (polyethylene glycol) precipitation followed by column chromatography using sephadex g-200. their efficacy was studied in guinea pigs, and the results compared with commercial japanese vaccine (green cr...

background: in this study we have prepared the iga solution from normal human plasma using plasma fractionation and ion exchange chromatography. materials and methods: using fractionation of plasma with cold ethanol (starting with 8% ethanol), fraction iii was prepared as a suitable source for iga preparation. then it was treated with caprylic acid for separation of impurities. for enrichment o...

Simian pituitary growth hormone was prepared in homogeneous form by sequential application of exclusion chromatography on Sephadex G-100, ion exchange chromatography on diethylaminoethyl Sephadex with a single eluent, and density gradient column electrophoresis. DEAESephadex chromatography with a single eluent was also used to separate two biologically active components of human pituitary growt...
