Quantification of PCR products by phosphate measurement

2008

Various techniques for quantification of PCR are available. Most frequently, the densitometric intensities of ethidium bromide-stained PCR products separated in gels are compared after normalizing to the levels of housekeeping gene products such as beta-actin. More precise, but extremely time consuming, is the technique of competitive PCR. Newer methods, such as tracking amplification in real-time, have high start-up and maintenance costs (e.g., TaqMan, Applied Biosystems; LightCycler, Roche; I-Cycler, Bio-Rad). Here, I describe an alternative, simple technique to quantify PCR products by determining the entire phosphate released during PCR. The method can be performed using common laborato…
