zucchini yellow mosaic virus (zymv) is a potyvirus with a worldwide distribution. this virus causes serious economic losses in iran in many cucurbits. during 2002-2003, sam-ples were collected from squash fields in tehran province. five isolates (z1, z2, z3, z4 and z5) were inoculated on 27 species of cucurbitaceae, chenopodiaceae, amarantha-ceae,solanacae, leguminosae and ranunculaceae. chenop...

seed protein profiles of 47 accessions belonging to eleven species and four tribes of grain legumes were studied, by extracting the total proteins from ten single seeds in each accession and performing sds-polyacrylamide gel electrophoresis. all eleven species were clearly recognizable from their protein banding patterns, but only phaseolus vulgaris expressed high intraspecific variations, ...

one of the most important forms of preharvest damage to wheat is caused by sunn pests. the insects insert their mouth parts into the immature grain and while injecting their saliva suck the milky juices. flour from damaged wheat results in low baking performance due to the bug proteolytic enzymes’ injected which cause the breakdown of gluten structure in the dough. in the present study three wh...

background: mycobacterium bovine, as the etiology of bovine tb, involves human in some cases and with mycobacterium tuberculosis are regarded as global health problems. the aim of this study was to extract and compare protein profile of these strains in order to achieve effective biomarkers for diagnosis and the vaccine components. materials and methods: first, the clinical samples were culture...

INTRODUCTION SDS-polyacrylamide gel electrophoresis (SDS-PAGE) represents the second-dimension separation of two-dimensional (2D)-PAGE. Large-scale proteome analysis usually requires simultaneous electrophoresis of batches of second-dimension SDS-PAGE gels to maximize the reproducibility of 2D electrophoresis protein profiles. This requirement is most easily met using multiple, vertical second-...

snail is one of the worst causes of food allergy. thus, the aim of this study was to identify the major and minor allergens of the local marine snail ( cerithidea obtusa ) and subsequently to investigate the impacts of heat treatment on the ige-binding activity of snail allergens. proteins from raw and heat-treated snails (boiled, roasted and fried) were extracted and then resolved by sodium do...
