DTK406, Peanut Source Component Arab2 Gene Nucleic Acid Detection Kit (Fluorescent PCR Method). This kit uses TaqMan probe method for real-time fluorescence PCR technology, designs a pair of flower derived component Arab2 gene sequence specific primers, and combines them with a specific probe to amplify and detect the DNA of flower derived component Arab2 gene in vitro using fluorescence PCR technology, thus achieving the goal of rapid detection.
