Our earlier method to detect and quantitate sulfamethazine (SMZ) in milk at the 10 ppb level was modified to quantitate SMZ in pork tissue. Sulfabromomethazine (SBZ) is added to the tissue as an internal standard. SMZ and SBZ are extracted from the t

Sulfamethazine (SMZ) is effective in the treatment of bacterial infections in food producing animals but its use is prohibited in dairy cows. Nevertheless, a 1988 survey of milk in ten cities conducted by the Food and Drug Administration revealed the

The proteins isolated from nonfat dry milk (NDM) which had been prepared with a high-temperature treatment (85°C for 30 min) were shown by sedimentation field-flow fractionation (SdFFF) to be highly susceptible to aggregation, with the formation of

The mass distributions of reconstituted bovine casein micelles formed, in various media, with four preparations of whole casein were determined by sedimentation field flow fractionation. Two of the casein preparations were made from the milk of a sin

A method for the solid-phase extraction and thin-layer chromatographic (TLC) quantitation of sulfamethazine (SMZ) residues in milk is presented. Sulfabromomethazine was added as an internal standard to homogenized milk samples which were then diluted

Many separations of proteins are performed on hydrophobic interaction columns. Elution is achieved with salt gradients, but anomalous elution behavior is observed often. In this investigation, we show that the binding of salt to proteins may explain

The retention behaviour of reference proteins on commercial siliceous size-exclusion supports was studied. Sorption was observed on both surface modified and unmodified supports. When sodium dodecylsulfate was added to the aqueous mobile phase, norma

The ion-exchange properties of several commercial bonded-phase supports were studied to determine their applicability for protein separations. Because of the complexity and multiple functionality of protein molecules, UV-absorbing ions with unit char
