What are the labels of the probe which is used in the Internal Control Assay for detection of the IC?

In the QuantiFast Pathogen + IC kit, the probe is labeled with MAX-NHS ester (MAX) as the reporter dye which has a spectrum equivalent to HEX, JOE or VIC dyes. IowaBlack is used as the quencher dye. IowaBlack is a non-fluorescent quencher (dark quencher).
