Isolation and Purification of Bioactive Proteins from Bovine Colostrum
Bovine colostrum is the milk secreted by cows during the first few days after parturition. It contains many essential nutrients and bioactive components, including growth factors, immunoglobulins (Igs), lactoperoxidase (Lp), lysozyme (Lys), lactoferrin (Lf), cytokines, nucleosides, vitamins, peptides and oligosaccharides, which are of increasing relevance to human health. Much research work has...
متن کاملProteomic Analysis of Whey from Bovine Colostrum and Mature Milk
The aim of this study was to standardize a methodology to obtain two-dimensional (2D) maps of whey proteins from bovine colostrum and mature milk, using two-dimensional electrophoresis, in order to identify the minor proteins by matrix-assisted laser desorption/ionization tandem time-of-flight mass spectrometry (MALDI TOF/TOF MS). A total of 38 proteins were identified, 20 spots in the colostru...
متن کاملBovine kappa-casein gene polymorphism and its association with milk production traits
Point mutations in exon IV of the bovine κ-casein (CSN3) gene determine two allelic variants, A and B. These variants were distinguished by polymerase chain reaction and restriction fragment length polymorphism (PCR-RFLP) analysis in the indigenous Sahiwal and Tharparkar cattle breeds. DNA samples (252 Sahiwal and 56 Tharparkar) were analyzed for allelic variants of the CSN3 gene. Polymorphism ...
متن کاملSequencing and Bioinformatics Analysis of Kappa-Casein Exon 4 Gene in Iranian Bacterianus and Dromedaries Camels
Kappa-casein, as a major protein component in mammalian milk, plays an essential role in formation and stabilization milk micelles and preventing them from aggregating and therefore, helping to keep calcium phosphate in solution and transfer of calcium and phosphors from animal milk to consumers. Therefore, the objective of the current study was to investigate genetic and phylogenetic analysis ...
متن کاملImmune components of bovine colostrum and milk.
Colostrum and milk provide a complete diet for the neonate. In ruminants, colostrum is also the sole source of initial acquired immunity for the offspring. Milk therefore plays an important role in mammalian host defense. In colostrum, the concentration of immunoglobulins is particularly high, with IgG being the major immunoglobulin class present in ruminant milk, in contrast to IgA being the m...
