Abstract: A reverse transcriptase (RT) assay kit for analysis of RT activity in biological samples is described. The kit comprises solid phase bound prA and/or pdA template(s) obtainable by contacting a polystyrene-based solid phase with a 1-methylimidazole-containing coupling solution, and RT-type adapted assay components selected from a buffer, divalent metal ion, chelator, polyamine, RNase inhibitor, reducing agent, salt, stabilizing agent, and detergent, and deoxynucleotide triphosphate, primer, protective agent and concentrated washing buffer, and optionally lyophilized reference enzyme(s), and further optionally lyophilized alkaline phosphatase conjugated anti-BrdU monoclonal antibody, alkaline phosphatase substrate buffer and alkaline phosphatase substrate, and written instructions for use of the assay kit. Further, a method and a use of the assay kit for the qualitative and quantitative analysis of RT activity in a biological sample, optionally followed by evaluation of the status of a RT activity related disorder or disease based on the result of the analysis of the RT activity, are disclosed.
