Nucleic Acid Amplification Technique for Rapid Diagnostic Analysis
CDC researchers developed a simple target-specific isothermal nucleic acid amplification technique, termed Genome Exponential Amplification Reaction (GEAR). The method employs a set of four primers (two inner and two outer). The outer primer pair targets three specific nucleic acid sequences at a constant 60°C, while the inner pair of primers accelerates and improves the sensitivity of the assay.
The GEAR technique is an improvement over loop-mediated isothermal amplification (LAMP) in three ways.
