ANTQ300 is a kind of high sensitive biosensor combining microelectronic high frequency technology and bio-recognition technology applied in real time detection of interactions between bio-molecules and concentration of bio-molecules. It includes a precision design FIA system, convenient operating software, and sensing chip that can be used repetitively. The operating principle of ANTQ300 is to measure the mass changes on the surface of the chip. Radioactive material or fluorescein is not required to achieve the purpose of detection.

It is suitable for use in interacting molecules including protein/protein, antigen/antibody, enzyme/substrate, drug/receptor, nucleic acid/nucleic acid, and nucleic acid/protein, etc.
