    摘要: Hydrophobic α(1→4)glucopyranose polymers with enhanced degradation properties are described. Between the α(1→4)glucopyranose polymeric portion and the hydrophobic portion exists a linker portion having a silyl ether chemistry that facilitates degradation of the polymer. Biodegradable matrices can be formed from these polymers, and the matrices can be used for the preparation of implantable and injectable medical devices wherein the matrix is capable of degrading in vivo at an increased rate. Matrices including and capable of releasing a bioactive agent in vivo are also described.

    摘要: The invention provides compositions, kits, and methods for performing colorimetric analysis. A substrate is reacted to generate a chromogenic reaction product, and a reaction stop reagent that is a sulfonic acid is added to stop and stabilize the reaction product. The absorbance properties of the chromogenic reaction product can be maintained over significantly longer periods of time of that of conventional reagents and methods. The sulfonic acid can be used in assays such as ELISAs in order to provide a more accurate and safer detection of analytes in a biological sample.
