Units contain a lateral flow strip designed to detect a biotin and FITC (or FAM) labelled amplicon. Detection is performed in a sealed cartridge preventing cross-contamination from amplified products. U-star disposable units can be used to detect amplification products generated when using a TwistAmp® nfo kit in combination with a TwistAmp® nfo probe and labelled amplification primer. See U-Star guide  for further information.
