What is HPA

Hybridization protection assay


TMA is an RNA amplification method driven by what 2 enzymes?

Reverse transcriptase

RNA polymerase


Reagent added to a completed TMA reaction to perform a Hybridization Protection Assay (HPA)

Acridinium ester (AE)-labeled DNA probes


How does isothermal amplification differ from PCR?

Target amplification occurs at a SINGLE temperature


Relative to PCR, how does TMA reduce the risk of false positives in subsequent assays?

TMA produces RNA amplicons

They're unstable outside reaction tube = low risk as a contaminant
