ABSTRACT:
Systems and methods for normalizing detected emission data collected in real-time polymerase chain reaction (RT-PCR) and other reactions, are provided. In some embodiments, a sample plate can be loaded with a fluorescent dye and subjected to a real-time PCR reaction. During the initial cycles, detected emissions that correspond to the background signal contributed by the plate, buffer, and other non-reactant pieces of the reaction system and chemistry can be identified. The raw emission data can be normalized by dividing the emission data by the identified baseline signal. According to various embodiments, the normalized amplification profile can normalize to an initial value of 1, because the actual signal emerges from the baseline at the point exponential growth begins. A normalized amplification profile based on a ratio to the baseline can create a more uniformly scaled amplification curve across different samples, filters, wells, dyes, or machines.
