Há 15 horas · A Reação em Cadeia da Polimerase (PCR, do inglês Polymerase Chain Reaction) é uma técnica revolucionária na biologia molecular, usada para amplificar sequências específicas de DNA. Um componente crucial para a realização da PCR é o ciclador térmico, um dispositivo que controla precisamente as mudanças de temperatura necessárias para cada etapa do processo.
Há 5 dias · Polymerase chain reaction (abbreviated PCR) is a laboratory technique for rapidly producing (amplifying) millions to billions of copies of a specific segment of DNA, which can then be studied in greater detail.
Há 4 dias · PCR-based techniques are methods that rely on the polymerase chain reaction (PCR) to amplify stretches of DNA by creating many identical or near-identical copies....
Há 5 dias · The polymerase chain reaction (PCR) is a vital step in many molecular biology workflows, allowing researchers to amplify specific DNA sequences. To avoid contamination during this sensitive assay, it's essential to set up a well-organized lab.
Há 1 dia · Reverse transcription polymerase chain reaction (RT-PCR) first uses reverse transcription to obtain DNA, followed by PCR to amplify that DNA, creating enough to be analyzed. RT-PCR can thereby detect SARS-CoV-2, which contains only RNA. The RT-PCR process generally requires a few hours.
Há 5 dias · In this video, we will introduce the basics of the Polymerase Chain Reaction, or PCR. We’ll review the history of PCR, typical components and principles of the reaction, polymerases available, PCR reaction types, and the various applications of this widely used molecular biology technique.
