1. A method of detecting one or more RNA comprising the steps of:
- (a) reverse transcribing one or more RNA target using one or more linear reverse transcription primer comprising in a 5′
to 3′
direction(i) a primer segment,(ii) a non-target probe segment, and(iii) a 3′
target specific segment that anneals to a RNA target;
(b) amplifying one or more RNA or RNA segment from all or part of the reverse transcription reaction using a first amplification primer that anneals to the 3′
end of a reverse transcribed RNA target and a second primer that anneals to a sequence complementary to the primer segment; and
(c) detecting amplification of a target nucleic acid.

Abstract
Embodiments of the invention include methods of detecting one or more RNA by reverse transcribing one or more RNA target using one or more reverse transcription primer comprising in a 5′ to 3′ direction (i) a primer segment, (ii) a probe segment distinct from the primer segment, and (iii) a 3′ target specific segment that anneals to a RNA target; amplifying one or more RNA from the reverse transcription reaction using a first amplification primer that anneals to the 3′ end of a reverse transcribed RNA target and a second primer that anneals to a sequence complementary to the primer segment; and detecting amplification of a target nucleic acid.

20. A method of detecting an miRNA in a sample comprising the steps of:
-
(a) obtaining a RNA sample; (b) reverse transcribing one or more miRNA target in the RNA sample using one or more linear reverse transcription primer comprising in a 5′
to 3′
direction(i) a primer segment, (ii) a non-target probe segment, and (iii) a 3′
target specific segment that anneals to a miRNA target;(c) amplifying the product of the reverse transcription reaction using a first primer that anneals to the 3′
portion of a reverse transcribed target miRNA and a second primer that anneals to a sequence complementary to the primer segment; and(d) detecting amplification of the probe segment. - View Dependent Claims (21, 22)

23. A method of assessing a pathological condition comprising the steps of:
-
(a) reverse transcribing RNA in a RNA sample from a subject having, suspected of having, or at risk of developing a pathological condition using a reverse transcription primer specific for one or more RNA associated with one or more pathological condition using one or more linear reverse transcription primer comprising in a 5′
to 3′
direction(i) a universal primer segment, (ii) a non-target probe segment, and (iii) a 3′
target specific segment that anneals to a RNA target;(b) amplifying the product of the reverse transcription reaction using a first primer that anneals to the 5′
portion of a target RNA and a second primer that anneals to the universal primer segment of the reverse transcription primer; and(c) detecting amplification of the probe segment of the reverse transcription primer. - View Dependent Claims (24, 25, 26)
