WebThe Basics: RT-PCR. RT-PCR (reverse transcription-polymerase chain reaction) is the most sensitive technique for mRNA detection and quantitation currently available. Compared to the two other commonly used techniques for quantifying mRNA levels, Northern blot analysis and RNase protection assay, RT-PCR can be used to quantify mRNA levels … WebDec 28, 2024 · The most important factor in choosing a DNA ladder is the expected size of the DNA bands in your experiment. You want to make sure that the range of the DNA ladder, from its smallest to its largest fragment, includes the expected size of the DNA fragments you are testing (Figure 1). For example, if you are expecting small DNA …
WebThe benefits of real-time PCR are that it is easy, accurate, and can scale to high throughput. Another advantage of real-time PCR is that the bioinformatic analysis is less complex … WebThe final preparation was stored at −20 °C and used as templates for polymerase chain reaction (PCR). Allele discrimination of the three studied SNPs was assessed with the ABI StepOne™ Real-Time PCR System (Applied Biosystems, Foster City, CA, USA) and analyzed using SDS version 3.0 software (Applied Biosystems), with the TaqMan assay .
