Actinidin was used to hydrolyse proteins in whey protein isolate (WPI) and milk concentrate (MPC) reduce immunoreactivity of β-lactoglobulin (β-LG) αs1-casein (αs1-CN). Samples were incubated at an enzyme substrate ratio 1:100 (5.21 units actinidin activity g−1 protein) 10 or 60 °C for up 31 5 h, respectively. Protein hydrolysis determined by the degree SDS-PAGE. Antigenicity hydrolysates β-LG ...

Extracellular microcapsules have been demonstrated on cells of most serotypes of Streptococcus mutans by electron microscopy, using bacterial strains of the various serotypes and peroxidase labeled or unlabeled immune serum. A correlation was noted between the amount of capsular substance on the strains of S mutans examined and degree of antigenicity as expressed by the indirect fluorescent ant...

With the use of a newly developed solid-phase radioimmunoassay method, the major antigenic determinants of human small-intestinal goblet-cell mucin were investigated and related to the overall tertiary structure of the mucin. Preliminary hapten inhibition studies with various oligosaccharides of known sequence and structure suggested that the determinants did not reside in carbohydrate. Exhaust...

The rapid and consistent mutation of influenza requires frequent evaluation of antigenicity variation among newly emerged strains, during which several in-silico methods have been reported to facilitate the assays. In this paper, we designed a structure-based antigenicity scoring model instead of those sequence-based previously published. Protein structural context was adopted to derive the ant...

conclusions results indicates that antigenic region of recombinant caga protein were recognized as an antigen , so it might be a candidate for the development of h. pylori vaccine, elisa kit designs and serological diagnosis of h. pylori infections. background helicobacter pylori is a human pathogen that causes chronic gastritis, which playsrole in gastric and duodenal ulcers, is also involved ...

Nentwich I . , Szépfalusi Zs. , Kunz C. , Spuergin P. , Urbanek R.: Antigenicity for Humans of Cow Milk Caseins, Casein Hydrolysate and Casein Hydrolysate Fractions. Acta Vet. Brno 2004, 73: 291-298. Cow milk casein consists of several fractions each of which have different structure and differing antigenicity. The aim of the study was to investigate the capacity of cow milk casein, casein frac...

individual preparation of two human t-cell lymphotropic virus type i (htlv-i) diagnostic gst fused peptides (mta-1 and gd21) is time-consuming and expensive. the aim of this study was to design a novel single chimeric antigen (sca) to obviate separate expression of proteins and reduce the cost of reagent preparation.structural protein fragments, including immunodominant b cell linear epitopes, ...
