an attempt has been made to analyze the distribution of the beta-lactoglobulin genotype in swamp buffaloes and murrah buffaloes utilizing polymerase chain reaction-restriction fragment length polymorphism(pcr-rflp). blood samples were taken from 50 swamp buffaloes and 50 murrah buffaloes. the dna was extracted by the phenol-chloroform method. the pcr-rflp was performed using beta-lactoglobulin ...

We have previously demonstrated that Lactobacillus paracasei NCC2461 may help to prevent cow's milk allergy in mice by inducing oral tolerance to beta-lactoglobulin (BLG). To investigate the mechanisms involved in this beneficial effect, we examined the possibility that L. paracasei induces tolerance by hydrolyzing BLG-derived peptides and liberating peptides that stimulate interleukin-10 (IL-1...

β -Lactoglobulin is capable of binding fat-soluble compounds including vitamin A palmitate and is suggested to specifically enhance intestinal uptake of retinol. In this study, bioavailability of a vitamin-A-retinyl palmitate complex in skim milk and in water-based liquids was investigated in vitamin-A-depleted rats. First, rats were fed a vitamin-A-free pellet diet for 6 wk and were thereafter...

BACKGROUND Cow's milk-derived whey hydrolysates are nutritional substitutes for allergic infants. Safety or residual allergenicity assessment of these whey hydrolysates is crucial. Currently, rat basophilic leukemia RBL-2H3 cells expressing the human IgE receptor α-chain (huFcεRIα-RBL-2H3), sensitized with serum IgE from cow's milk allergic children, are being employed to assess in vitro residu...

Cow milk is an important source of food protein for children, however, it could lead to allergy, especially infant. α-lactalbumin (α-LA) and β-lactoglobulin (β-LG) from whey make up a relatively high proportion proteins have received widespread attention as major allergens in milk. However, few studies identified the epitopes both simultaneously. In this study, ImmunoCAP indirect ELISA were fir...

The fractal structure of the aggregates in food protein gels was analyzed. Three kinds of food protein gels were prepared: (1) β-lactoglobulin (β-LG) gel; (2) 11S soybean globulin gel; and (3) caseinate gel. From the concentration dependence of the gel elasticity, the fractal dimensions Df of the aggregates in the gels were evaluated, according to the theory of Shih et al. These gels showed the...

An ELISA was applied to measure IgG sub-class antibodies to cow's milk beta-lactoglobulin (BLG), alpha-lactalbumin (ALA) and alpha-casein (AC) and to hen's egg ovalbumin (OA) in the sera of nineteen adult patients with milk intolerance causing either asthma, eczema or both. Results were compared with those of forty blood donors and twenty adult patients with either asthma or eczema due to inhal...
