Spinach is the quintessential healthy food, and itâs no surprise that itâs also high in potassium. Bananas get a lot of attention for their potassium content, but ounce for ounce spinach bests them in the potassium department.
New Applications. Quantitative polymerase chain reaction (qPCR) is used to simultaneously detect a specific DNA sequence in a sample and determine the actual copy number of this sequence relative to a standard. In real-time PCR, the DNA copy number can be established after each cycle of amplification.
The method of choice for nucleic acid (DNA, RNA) quantification in all areas of molecular biology is real-time PCR or quantitative PCR (qPCR). The method is so-called because the amplification of DNA with a polymerase chain reaction (PCR) is monitored in real time (qPCR cyclers constantly scan qPCR plates).
