Conventionally prepared immune serum globulin frequently produces severe side effects when administered intravenously. A modified preparation in which 4 to 5 interchain disulfide bonds have been reduced and alkylated has been made for intravenous use. However, reduction and alkylation may affect Fc-mediated functions of immunoglobulin G, particularly its ability to fix complement by the classic...

The colloid or protein osmotic pressure (Pi) is a function of protein molarity (linear) and of Donnan and other effects. Albumin is the major osmotic protein, but also globulins influence Pi. Equations based on concentrations of albumin and nonalbumin (globulin concentration + fibrinogen concentration) protein approximate Pi better than albumin alone. Globulins have a wide range of molecular we...

ONSIDERABLE TIME AND EFFORT has been devoted to the problem of fractionating serum protein simply, reliably, and rapidly, and at the same time in conformity with the free electrophoretic separation into albumin and a-, fi-, and 7-globulins. Much progress has been made, but discrepancies remain, especially in connection with aand -gIobulins. A few years ago Wolfson, Cohn, et at. (1) devised a re...

BACKGROUND Serum electrophoretic profiles in cats are poorly characterized with respect to the proteins that comprise the globulin fractions, and interpretation of the electrophoretograms is routinely done in the absence of information about identity of the proteins found within each fraction. OBJECTIVES The aims of this study were to compare protein fractions separated by serum protein elect...

Widely differing results were obtained for urinary protein determinations in male rats using 2 test strips and a quantitative Coomassie Blue sodium dodecyl sulphate method. A comparison of the sensitivity of the protein methods with respect to rat albumin and alpha 2U globulin was made; both test strips were found to be relatively insensitive to the presence of alpha 2U globulin. Resultant limi...

This study was conducted to compare the bio-efficacy of herbal methionine (H-Met) relative to DL-methionine (DL-Met) on 160 “Ross 308” broiler chickens. DL-Met and H-Met were added to the basal diet in eight experimental treatments with three and four concentrations respectively in starter, grower and finisher period. Blood parameters which were measured at 24 and 42 days of age consisted of: s...

The demonstration of the association between a positive colloidal gold reaction and an increase in the y-globulin in the cerebrospinal fluid (Kabat, Landow, and Moore, 1942) has stimulated further study of this protein fraction. An increase in this moiety in the spinal fluid of patients with multiple sclerosis has been reported by workers using freesolution and paper electrophoresis, as well as...
