Turbidimetric determination of haptoglobin.
A specific, accurate and simple determination of haptoglobin is described with an antiserum against the antigenic determinants of the three haptoglobin phenotypes 1-1, 2-1 and 2-2. Antihaptoglobin is the determining factor in the formation of an antigen-antibody complex with maximal light absorption properties. Haptoglobin concentration is expressed as hemoglobin binding capacity. For the three...
متن کاملThermal analysis of cellulose esters prepared from different molecular weight fractions of high α-cellulose pulp
High α-cellulose has been dissolved in two non-degrading solvent systems like dimethyl sulfoxide/paraformaldehyde (DMSO/PF) and N,N-dimethyl acetamide/lithium chloride (DMAc/LiCl) and then fractionated to different molecular weight fractions by regeneration technique. Esters of the different molecular weight fractions of cellulose have been prepared having substitution chain length of C2-C5 usi...
متن کاملElectrophoretic determination of vanilmandelic acid (VMA) in urine by direct application to cellulose acetate.
‘THE VALUE of vanilmandelic acid (3-methoxy-4-hydroxymandelic acid, 1/MA) in urine for the diagnosis of pheochromocytoma is well recognized. The comprehensive review of VMA analysis by Sunderman (1) reiterates that there is a large difference between normal and pathologic 24-hr. urinary excretion of 1/MA. Such a sharp difference in concentration makes VMA analysis adaptable to a semiquantitativ...

15 صفحه اولDetermination of apolipoprotein E in high density lipoprotein fraction by immunofixation method and turbidimetric immunoassay after precipitation.
Apolipoprotein E (apoE) in high density lipoprotein (HDL) fraction (HDL-fr) was determined by the immunofixation method and turbidimetric immunoassay (TIA) after precipitation with phosphotungstic acid/MgCl2 in normolipidemic control subjects and patients with type IV hyperlipemia and hyper HDL-cholesterolemia. Immunofixation assay revealed two major bands of apoE in whole serum: one in the alp...
