Genetic polymorphism at the β-lactoglobulin (β-LG) loci in indigenous sheep breeds (Tsigai, Racka, Pramenka) was determined. Altogether 904 sheep were genotyped for the presence of the A, B and C alleles of β-lactoglobulin by PCR-RFLP. The AB genotype was the most common and the β-lactoglobulin A was the most frequent in the Cokanski Tsigai (54%), while the B allele was the most common in the R...

the objective of this study was to determine the polymorphism of bovine β-lactoglobulin (β-lg) gene and its association with milk production traits in iranian najdi cattle. blood samples were collected from 80 najdi cattle from the najdi cattle breeding station located in shoshtar, khuzestan. polymerase chain reaction (pcr) and restriction fragment length polymorphism (rflp) techniqus were used...

Two major milk whey proteins, β-lactoglobulin and α-lactalbumin, are among the main cow milk allergens and can cause allergy even at a very low concentrations. Therefore, these proteins are interesting targets in food analysis, not only for food quality control but also for highlighting the presence of allergens. Herein, a sensitive analysis for β-lactoglobulin and α-lactalbumin was developed u...

This data article contains complementary results related to the paper "Effect of metal ions on the binding reaction of (-)-epigallocatechin gallate to β-lactoglobulin" (Zhang et al., 2017) [1]. Data was obtained by circular dichroism (CD) spectroscopy to investigate potential β-lactoglobulin (β-Lg) conformational changes with different concentrations of EGCg and Cu2+ or Al3+ added to β-Lg. 500 ...

In ideal proteins, only native interactions are stabilized step-by-step in a smooth funnel-like energy landscape. In real proteins, however, the transient formation of non-native structures is frequently observed. In this review, the transient formation of non-native structures is described using the non-native helix formation during the folding of β-lactoglobulin as a prominent example. Althou...

Cow's milk protein allergy (CMPA) represents one of the leading causes food in infants and young children. The immune reaction mainly due to casein β-lactoglobulin protein. Many systems are affected specially GIT,respiratory system skin.

The formation of fibrocartilage during articular cartilage regeneration remains a clinical problem affecting adequate restoration in joints. To stimulate chondrocytes to form cartilage, we investigated the use amyloid fibril-based scaffolds. proteins α-synuclein, β-lactoglobulin, and lysozyme were induced self-assemble into fibrils and, dialysis, formed micrometer scale networks that resemble e...

ABSTRACT The interaction between whey carrier protein β-lactoglobulin B and (-)-epicatechin, a major dietary flavonoid with a wide range of health-promoting biological activities, was investigated by Fourier transform infrared spectroscopy in physiological conditions. Amide I spectra of epicatechin - β-lactoglobulin complexes, in D2O buffer solutions, pD= 6.8, at molar ratios from 0.5:1 to 15:1...

We perform Atomic Force Microscopy and numerical simulations of a bimodal solution containing long, semiflexible β-lactoglobulin fibrils and short, flexible β-lactoglobulin linear aggregates at an air-water interface. Short aggregates orient perpendicular to fibrils at very short distances and preferentially parallel at intermediate distances. At even larger distances an isotropic distribution ...

Here, we study films of proteins over planar surfaces and protein-coated microspheres obtained from the adsorption of three different proteins ( β -casein, β -lactoglobulin and bovine serum albumin (BSA)). The investigation of protein films in planar surfaces is performed by combining quartz crystal microbalance (QCM) and atomic force microscopy (AFM) measurements with all-atomic molecular dyna...
