Technology Overview

The instrument adopts reverse hybridization assay for qualitative analysis of virus sub-types. When specimens to be tested are added into specimen slot, the instrument will automatically add process-required reagent into Chip reagent slot, respectively extract DNA and amplify PCR under the drive of micro-pumps on Chip, and finally transfer amplified products to Chip test area, and the amplified products will undergo reverse hybridization with detection probe covered with virus sub-types. If the amplified products contain amplified products of target gene, they can be captured by probe on the Chip; through enzyme reaction, there will be corresponding spots on specific position after coloration, and virus sub-type of original specimen can be judged out. If this is a negative specimen, there will be no spot on the position of probe of each virus sub-type.
