chrysanthemum cut flower is not sensitive to ethylene and its vase life depends on vascular blockage. in order to evaluating of effect of antibiotics and essential oils on the vase life and quality characteristics of chrysanthemum cut flower an experiment carried out based on a rcd with 10 treatments: artemisia at 3 levels (10, 30 and 50 %), amoxicillin at 3 levels (100, 200 and 300 mg l-1), ri...

the oil and protein content of three varieties of water melon seeds namely, chillian black, dixy queen and charlston gray were determined. the soluble proteins were studied and measured by paper chromatography and amino acid analyzer. the results indicated that oil content of the seeds was 43, 53 and 45% and protein content was 27, 23, and 34% respectively. the soluble proteins contained all th...

Background: Dense granule antigens (GRA antigens) of Toxoplasma gondii induce strong antibody response in humans and are considered as useful diagnostic antigens. Previous studies reported expression of amino terminal GRA8 protein in fusion with large tags such as glutathione-S-transferase. The present study aimed to produce soluble full length immunogenic GRA8 in bacteria. Methods: GRA8 comple...

in order to study the yield and forage quality of intercropping barley (hordeum vulgare) and mustard (sinapis alba) in different planting dates, a factorial experiment based on randomized completely block design with three replications was carried out at farm research station, gonbad -e- qabus university. factors were included as three planting dates (15 november, 6 and 20 december 2006) and fo...

Three cannulated Tswana steers were used to investigate the rumen degradability of mopane worm (Imbrasia belina) by measuring the amount of dry matter (DM) and crude protein (CP) disappearing at incubation periods up to 72 h. The effective degradability (ED) of DM and CP in the rumen was calculated at outflow rates of 0.03 / h (ED0.03) and 0.05 / h(ED0.05). Rumen degradable CP (RDP) was estimat...

Selection of a system for successful recombinant protein production is important. The aim of this study wasto produce high levels of human interleukin-2 (hIL-2) in soluble form. To this end, the pET32a vector inEscherichia coli BL21 (DE3) was used as an expression system, since it was previously used for the productionof mouse IL-2 in soluble form. The results indicated that c...

A sweet water-soluble protein that reminds stable over wide ranges of temperature and pH, Brazzein has various applications. Its tastes like cane sugar but have no calories. However, the extraction of brazzein from its natural source is expensive and not applicable. In this study we used recombinant DNA technology to provide an alternative option for cheaper mass production of brazzein. A brazz...
