Nephelometry of apolipoprotein B in human serum.
We studied the development of light scattering in the reaction between anti-apolipoprotein B and apolipoprotein B in intact very-low-density lipoproteins (I) and low-density lipoproteins (II) as well as in lipoproteins treated with lipases, and found considerable differences in the kinetics of the immunoreaction for the two lipoprotein classes. Pre-incubation with triglyceride lipase and choles...
متن کاملEVALUATION OF SERUM IgG SUBCLASS LEVELS IN ASTHMATIC AND ATOPIC CHILDREN WITH RECURRENT INFECTION
Serum IgG subclass levels were measured using an indirect immunoenzymatic assay (ELISA) with monoclonal antibodies in 16 children with asthma and 13 children with atopy who had mostly recurrent infections. Seven of the asthmatic children had marked low or low normal levels of IgG4, six had marked low or low normal levels of IgG 3, two had marked low normal levels of both IgG2, and IgG 3 and...
متن کاملAbnormal serum IgG subclass pattern in children with Down's syndrome.
Susceptibility to infections is a well known feature of Down's syndrome. The possible relation between this predisposition and the serum concentrations of the IgG subclasses was studied in 38 children with Down's syndrome aged 1-12 years. An age matched group of 50 healthy children served as controls. The serum concentrations of IgG1 and IgG3 were significantly raised among children with Down's...
متن کاملHUMAN IgG SUBCLASS LIQUID REAGENT KITS
In normal adults, IgG constitutes approximately 75% of the total serum immunoglobulins. Within the IgG class, the usual order of concentration of the 4 subclasses is IgG1> IgG2> IgG3> IgG4, but the actual concentration of each may vary markedly between individuals. The four IgG subclasses show considerable differences in their properties, including ability to fix complement, to bind to macropha...
متن کاملIgG subclass serum levels in juvenile chronic arthritis.
IgG subclass levels of sera from 26 patients with juvenile chronic arthritis (JCA) were determined by means of mouse monoclonal antibodies. Patients were divided into three groups according to clinical activity of the disease: active disease, partial remission, and remission. One hundred and sixty four age matched, healthy children served as controls. IgG subclass concentrations were log transf...
