I see big fuzzy bands around 100bp as well. They're most likely RNA contamination. To get rid of them, digest your RT-PCR products with RNAse-H. But if you just need to visualize your band of interest, and the fuzzy bands aren't getting in the way, it shouldn't be a problem. I usually input anywhere from 1-2 ug of RNA into my RT-PCR reaction using the ...
There is no single "ideal amount" of RNA. I would suggest you to do a titration curve to determine the best amount for your specific assay. The band at 100 bp could be a non-specific amplification. You could try to increase slightly the annealing temp to see if that removes (or reduces) the lower band. Alternatively, you can consider a different primer set ...
Thymine must make contact in two places on HIV-RT before being added to nucleotide strand. First contact is made with the fingers region then contact is made at the N-Site. Allosteric Regulation of HIV-1 Reverse Transcriptase by ATP for Nucleotide Selection
You have to design your primers properly. Usually, in real-time PCR, you don't choose a very long product. Ideal product size is 150-300. Next, see what your NRTI is analogous to. For e.g. if I am using AZT (Azathymidie), I would place my reverse primer at or after the last T. There are alternate techniques as well. You can use primer extension ...
