the genotypes for beta-lactoglobulin (blg) and calpastatin (cast) were determined by polymerase chain reaction (pcr) and restriction enzyme digestion and genotyped for calpain (capn) by pcr-sscp method in a native iranian breed sheep, kordi. blood samples were collected from 100 pure bred kordi sheep from kordi breeding station located in shirvan, mashhad. the extraction of genomic dna was base...

Synthetic microporous membranes with functional groups covalently attached were used to selectively separate beta-lactoglobulin, BSA, and alpha-lactalbumin from rennet whey. The selectivity and membrane performance of strong (quaternary ammonium) and weak (diethylamine) ion-exchange membranes were studied using breakthrough curves, measurement of binding capacity, and protein composition of the...

Maximum likelihood methodology was used to estimate effects of both a marker gene and a linked quantitative trait locus (QTL) on quantitative traits in a segregating population. Two alleles were assumed for the QTL. In addition to the effects of genotypes at both loci on the mean of the quantitative trait, recombination frequency between the loci, frequency of the QTL alleles and the residual s...

Beta-lactoglobulins, belonging to the lipocalin family, are a widely studied group of proteins, characterized by the ability to solubilize and transport hydrophobic ligands, especially fatty acids. Despite many reports, the mechanism of ligand binding and the functional role of these proteins is still unclear, and many contradicting concepts are often encountered in the literature. In the prese...

Heterosexual transmission of human immunodeficiency virus type 1 (HIV-1) is the major cause of the ongoing AIDS epidemic. Application of chemical barrier methods is expected to contribute to the worldwide control of this epidemic. Bovine beta-lactoglobulin modified by 3-hydroxyphthalic anhydride (3-hydroxyphthalovyl-beta-lactoglobulin [3HP-beta-LG]) was shown to inhibit HIV-1, HIV-2, simian imm...

Correspondence analysis (CA) is one of the multivariate statistical techniques which examines relationships between different nominal variable categories in two-way or contingency tables. The aim this study to investigate Alpha-S1 Casein and Beta-Lactoglobulin gene polymorphisms Norduz Sheep by Analysis method. In study, frequencies CSN1S1 BLG obtained from Proje number TSA-2020-8930 were used....
