A Solid-Phase Enzyme-Linked Assay for Vitamin B12
A new solid-phase enzyme-linked competitive binding assay for vitamin B12 (cyanocobalamin) is described. The assay is based on the competition between analyte B12 molecules and a glucose-6-phosphate dehydrogenase-vitamin B12 conjugate for a limited number of R-protein binding sites immobilized on sepharose particles. After appropriate incubation and washing steps, the enzyme activity bound to t...
متن کاملEnzyme-linked immunosorbent assay for detection of antibodies to extractable nuclear antigens in systemic lupus erythematosus, with nylon as solid phase.
In this enzyme-linked immunosorbent assay (ELISA) for detection of antibodies against extractable nuclear antigens (ENA) in sera of patients with systemic lupus erythematosus (SLE), nylon is used as solid phase for antigen binding instead of the commonly used polystyrene surface. Optimal conditions for activation of the nylon beads, antigen coating, and other relevant factors have been investig...
متن کاملSolid phase enzyme-linked competitive binding assay for riboflavin.
A new solid-phase enzyme-linked assay for riboflavin (vitamin B2) is described. The assay is based on the competition between analyte vitamin molecules and a glucose-6-phosphate dehydrogenase-3-carboxymethylriboflavin conjugate for a limited number of riboflavin-binding protein sites immobilized on Sepharose particles. Significant improvements in conjugate catalytic activity and thus detectabil...
متن کاملNovel solid-phase assay of ketone bodies in urine.
This simple dip-and-read color-matching assay measures ketone bodies in urine. The result is matched with any of the seven colors provided in a color chart. The intensity and hue of the color formed depends on the concentration of acetoacetic acid and follows a gradation starting from light purple (0.2 mol/L acetoacetate) to dark purple and finally to dark violet (9 mol/L). The color developed ...
متن کاملAdaptation of an indirect enzyme-linked immunosorbent assay by purified gp51SU for detection of antibodies to bovine leukemia virus
The objective of this study was to compare an indirect ELISA, based on a purified 60 kDa envelope glycoprotein (gp51SU), with a Pourquire indirect ELISA for the detection of antibodies to the bovine leukemia virus. For conducting this research, 340 serum samples were collected from two different breeds of cows (Sarabi and Holestin) in different herds. Commercial ELISA revealed positive results ...
