New preventive approaches against dental erosion caused by acidic drinks and beverages include fortification of beverages with natural polymers. We have shown that the mixture of casein and mucin significantly improved the erosion-inhibiting properties of the human pellicle layer. This study aimed to investigate the effect of pellicle modification by casein, mucin and a casein-mucin mixture on ...

Casein kinase I from broccoli was purified approximately 65,000-fold by chromatography on phosphocellulose, phenyl-Sepharose, CM-Sephacel, and affinity chromatography on N-(2-aminoethyl)-5-chloroisoquinolone-8-sulphonamide (CKI-7)-Sepharose. The catalytic subunit of casein kinase I was identified as a 36-38 kDa polypeptide doublet by using the technique of activity gel assay after SDS/PAGE with...

The present work was carried out to analyse the κ-casein variants in five Indian goat breeds by SDS-PAGE, PCRRFLP and SSCP method. A total of 152 unrelated blood samples and 102 milk samples belonging to Barbari, Beetal, Marwari, Surti and Local MP (non-descript) goats were used for analysis. SDS-PAGE exhibited κ-casein allele A in all the breeds. Moreover PCR+RFLP analysis also confirmed the p...

The properties of the paracasein and casein preparations studied are compared in Table VI. See PDF for Structure I. Casein retains its characteristic solubility in NaOH: (1) after being exposed to a high degree of alkalinity during its preparation, (2) when recovered from partially hydrolyzed solutions in NaOH, and (3) after being kept for a prolonged time at the isoelectric point at 5 degrees ...

Two clones were isolated from a cDNA library corresponding to mRNAs which accumulate in mid-lactating (14 day) rabbit mammary gland and characterized by DNA sequencing. The two clones sequenced corresponded to two novel casein transcripts (pBRM5 and pBRM42). Relative mRNA abundances for the two clones were assessed by dot-blot analysis. Phylogenetic analysis and comparison of both pBRM5 and pBR...

Cattle breeds have a striking effect on milk, including milk composition and technological characteristics. This study aims to compare milk composition, acidification activity, viscosity, milk dispersion system stability and casein molecular weight among three buffalo breeds in China. The technological characteristics of milk produced by three cattle breeds of river buffalo (Murrah), crossbreed...
