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.
ï® Realâtime qPCR is the most sensitive and reliable method for detection and quantification of nucleic acids (DNA, cDNA, & RNA) levels. ï® It is based on detection and quantification of fluorescence emitted from a reporter molecule at real time.
