ABSTRACT:
A reagent such as a heat resistant enzyme is entrapped in a material such as wax or a liposome that releases the reagent when heated so the reagent is available for reaction. In a preferred embodiment, wax beads containing the reagent are prepared by injecting the reagent into beads of molten wax and cooling to solidify the wax. In another embodiment, droplets of a solution of the reagent are dropped through a layer of molten wax to coat the droplets with the wax and the coated droplets are cooled to solidify the wax. The entrapped reagents have application in nucleic acid hybridizations, polymerase chain reactions (PCR), reverse transcriptase reactions (RTR), nucleic acid sequencing, and product generating reactions such as colorimetic, fluorometric and chemiluminescent enzyme labeled immunoassays.
