Polymorphism of the b-lactoglobulin (b-LG) gene in 101 cows belonging to the Holstein herd and a superior cow, producing more than 150 Kg milk/day, together with four offsprings was investigated by the Polymerase Chain Reaction-Restriction Fragment Length Polymorphism (PCR-RFLP) method. In the Holstein herd, the alleles A and B of the b-LG gene had frequencies of 0.53 and 0.47, respectively. Th...

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 ...

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...

In this study, the genetic diversity of three milk protein genes namely beta-casein, kappacasein and beta-lactoglobulin was estimated in Turkish cattle breeds. Based on these genes, breeds in Turkey have been grouped as: 1) Eastern Anatolian Red, Anatolian Black and Southern Anatolian Red and 2) Turkish Grey, Turkish Holstein and Holstein Candidate Bulls. B alleles of the three studied genes, w...

OBJECTIVE To explore the use of β-lactoglobulin polymerized using microbial transglutaminase and heating to identify whether protein polymerization could reduce in vivo allergenicity and maintain in vitro and ex vivo immunoreactivity for use in tolerance-induction protocols. METHODS Based on previous protocols applied in mice and children, we performed in vivo challenges (using a skin prick t...

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...
