1. 1. Electrophoretic studies are made of mature phase milk “whey” proteins and blood serum proteins of echidna (Tachyglossus aculeatus) and platypus (Ornithorhynchus anatinus). The echidna milk bands are designated AM, those of platypus AG

High-performance liquid chromatography has been applied to determination of modifier activity in alpha-lactalbumin (alpha-LA). An amino-bonded column separates uridine diphosphate (UDP) (product), UDPgalactose (substrate), and uridine monophosphate (

1. 1. Individual blood samples from 144 Bali (Banteng) cattle [Bos (Bibos) javanicus] in the Northern Territory of Australia and from 61 Bali cross cattle, were examined by zone electrophoresis to determine the variants of haemoglobin, serum albumin

1. 1. Both α-lactalbumin and β-lactoglobulin-like proteins were detected in the whey fraction of feline milk by immunoblotting with rabbit antisera to α-lactalbumin and β-lactoglobulin, respectively. 2. 2. α-Lactalbumin was found to occur in bot

1. A comparison is made of gel electrophoretic patterns of the "whey" proteins of the milk of red (Macropus rufus) and eastern grey (Macropus giganteus) kangaroos at various stages of lactation. Qualitative and quantitative changes occur with time du

1. 1. Zone electrophoretic patterns of milk samples have been examined from 713 mares, and classified in terms of 5 anodic zones and 1 cathodic zone at pH 8.5 (NaOHH 3 BO 3 ). 2. 2. Zone 1 protein exhibits genetic polymorphism, there being 5 varia

SummarySkim milk samples from 126 Friesian and 147 Jersey cows in eight commercial herds were preheated at 85 °C for 30 min and concentrated to 200 g l−1total solids. A heat coagulation time–pH curve was determined at 120 °C for each treated sa

A new method, involving only gentle procedures, is described for the isolation of bovine β-casein. The optical rotatory dispersion (o.r.d.) and circular dichroism (c.d.) of the A1 variant, so isolated, are determined in the temperature range 2–60
