RNases / RNase A
Candidate category only. Match the stated sample, material, capacity, geometry and required output before comparison; experimental interchangeability is not established.
RT master mixes / Mixed-primer RT mixes
Mixed primers. 5× mix for short targets. The vendor lists 10 pg-1 µg total RNA.
RT master mixes / Mixed-primer RT mixes
Mixed primers. Uses an engineered reverse transcriptase with reduced RNase H activity. Check its own incubation program.

Reverse transcriptase enzymes / Engineered reverse transcriptases
Engineered reverse transcriptase with increased thermostability and reduced RNase H activity. Candidate for this workflow; confirm formulation, substrate and protocol compatibility before substitution.
Random primers
Random hexamer primer mixture with unmodified hydroxyl termini for cDNA synthesis and DNA replication. Candidate for this workflow; confirm formulation, substrate and protocol compatibility before substitution.
Random primers
Oligonucleotide primer for first-strand cDNA synthesis. Sequence length and anchoring differ between priming formulations. Candidate for the listed workflow; compare buffer, sample input and protocol requirements before substitution.

ALTERNATIVE DOES NOT MEAN IDENTICAL
Final groups are designed around experimental substitution requirements. Group membership is provisional until the necessary technical details have been verified for the intended experiment.
Start with your application, then verify the technical requirements against each manufacturer’s documentation.
