    摘要: The invention is a rapid, continuous test for glycated hemoglobin using a non-equilibrium affinity binding method. Agarose beads derivatized with 3-aminophenylboronic acid specifically bind glycated hemoglobin. This solid phase is incorporated into a sample processor card, modified to mix and to separate the test solution from the solid phase prior to absorbance readings. Two absorbance readings are made on the test solution, one immediately after mixing the reagent/diluent with the specimen, and one after a significant amount of binding has occurred. A linear correlation between total glycated hemoglobin and hemoglobin A.sub.1c permits standardization and reporting of units equivalent to % hemoglobin A.sub.1c. Stable glycated hemoglobin solutions for use as standards in the assay, and a method for preparing the standards are also disclosed.

    摘要: The present invention provides novel fluorescein derivative compounds having fluorescence spectrum and quantum yield characteristics similar to those of fluorescein. The compounds are readily synthesized and purified and are readily soluble in water at self-quenching concentrations. Significantly, due to the presence of polar polyhydroxy group substituents and the absence of metal-chelating groups, these fluorescein derivatives are susceptible to minimal leakage across liposome membranes and have fluorescence characteristics minimally sensitive to the presence of metal ions. Compounds of the invention are thus exceptionally suitable for use in the development of highly storage stable liposome preparations to be employed in immunolytic assays involving human body fluid samples.
