Lactoferrin and Serum Albumin of Human Casein in Colostrum and Milk

The Bacteriostatic Effects of Orally Administered Bovine Lactoferrin on IntestinalEnterobacteriaceaeof SPF Mice Fed Bovine Milk

“…The bovine lactoferrin content of the milk used was less than 10 /lg/g as estimated by rocket immunoelectrophoresis. 23 ) Native bLF (iron saturation 14.5°/,,) was prepared from fresh skim milk (Morinaga Milk industry Co., Zama City, Japan) by the method of Law and Reiter. 24) In experiment 2, the effects of bLFs with different iron saturation on the initial proliferation of faecal Enterohacteriaceae and on gastrointestinal Enterohacleriaceae were examined using five groups often mice each.…”

Re‐evaluation of the whey protein/casein ratio of human milk

“…This method was developed by Rowland in 1938 for the analysis of bovine casein (I). However, analyzing human milk by this method leads to varying amounts of whey proteins such as lactoferrin, serum albumin or sIgA in the casein pellets (2)(3)(4)(5). Thus, the reported discrepancy in the casein content of human milk samples can be explained in part by co-precipitation of whey proteins with casein.…”

A glyco-phosphoprotein in human milk

“…When human skim milk is acidified to pH 4-6, several components other than /?-or /c-casein are co-precipitated. Co-precipitation of lactoferrin and serum albumin has been reported by Nagasawa et al (1974), and lactoferrin was found in human whole casein (Azuma et al 1981) and in a crude /c-casein fraction (Yamauchi et al 1981). It has been demonstrated that lactoferrin interacts with such acidic proteins as serum albumin and casein (Heckman, 1971).…”
