Standard Dilution Series with the xxpress® qPCR Thermal Cycler

The success of a qPCR reaction is evaluated using a standard dilution series, the data from which is used to calculate the reaction efficiency and R2 values. Efficiency can be defined as the increase in amplicon per cycle, whilst R2 is the coefficient of determination. Ideally, the efficiency of a qPCR reaction would be 100%, […]

Detecting Aquatic Organisms Using eDNA

Nuclear or mitochondrial DNA that is released into the environment from an organism is known as environmental DNA or eDNA. The eDNA of a large number of aquatic organisms can be detected in water samples by qPCR, even when at very low concentrations. This technique is particularly useful when trying to locate rare species that are […]
