Aumentar os rendimentos cDNA Single-cell quantidades de mRNA em Laboratório Padrão Reações transcriptase reversa usando Microstreaming Acústico

This procedure increases CD NA yields from single cell quantities of mRNA. Start by equilibrating the micro mixer inside an incubator set to the desired reverse transcription reaction temperature. Then set up standard laboratory RT reactions, comprising single cell quantities of RNA in microliter volumes.

Position the reaction tube securely into the mixing holes, selecting appropriate mixing parameters and switch on the microm mixer. Ultimately, this procedure can be used to obtain increased CDNA yields through quantitative PCR As preparation for the RT reaction. Equilibrate the microm mixer in a 37 degree Celsius incubator for at least one hour.

In standard sterile nuclease free 200 microliter thin walled PCR tubes. Set up the reverse transcriptase reactions according to the supplier's instructions, except use single cell amounts of input total RNA. Now select the appropriate frequency and amplitude of microm mixing.

Next position the tube securely into the microm mixer. Then turn on the micro mixer. Allow the reaction to proceed for 60 minutes on completion, switch off the micro mixer and transfer the reactions to ice for immediate use in subsequent downstream applications compared to other methods, the primary advantage of microm mixing in the context of RT reactions is CD NA yield.

In this quantitative polymerase chain reaction analysis, the QPCR traces using primers designed to detect cDNA representing neuro one mRNA illustrates the effects of microm mixing for the first five minutes or the entire 60 minutes compared with duration of the RT reaction immediately prior to the RT incubation. MICROM mixing for the first five minutes did not result in significant improvement over ation. However, microm mixing for the entire 60 minutes produced a significant improvement of yield equivalent to 15 QPCR cycles.

Furthermore, melting curve analysis of QPCR demonstrates that micro mixing for the entire 60 minutes of the preceding R two reaction produces a consistent signal in duplicate samples as shown in the red traces. This is in contrast to the variant traces observed with microm mixing for the first five minutes as shown in blue or with ation only as shown in black gray traces are no template controls.
