The reagent kit is intended for use by trained professionals in the laboratory setting. en Tests performed using the cobas omni Utility Channel Reagent Kit are based on fully-automated sample preparation (nucleic acid extraction and purification), PCR amplification, and target detection technologies found in the cobas® 5800/6800/8800 Systems. The cobas® 5800 System is designed as one integrated instrument. The cobas® 6800/8800 Systems consist of the sample supply module, the transfer module, the processing module(s), and the analytic module(s). Automated data management is performed by the cobas® 5800/6800/8800 Systems softwares which assigns test results. Results can be reviewed directly on the system screen, exported, or printed as a report.Performance of tests using the cobas omni Utility Channel Reagent Kit relies on the cobas omni reagent concept, which is exclusive to the cobas® 5800/6800/8800 Systems. This concept enables use of the same sample preparation reagents (cobas omni MGP Reagent, cobas omni Lysis Reagent, cobas omni Wash Reagent, cobas omni Specimen Diluent, Proteinase, RNA internal control, Elution Buffer, and MMX-R1) for all tests run on the systems.All tests performed on the cobas® 5800/6800/8800 Systems furthermore utilize a single sample preparation process, the cobas omni sample preparation process. In summary, nucleic acid from samples, external controls, and added armored RNA (internal control) is simultaneously extracted; the nucleic acid is released by addition of proteinase and lysis reagent to the sample. The released nucleic acid then binds to the silica surface of the added magnetic glass particles. Unbound substances and impurities, such as denatured protein, cellular debris, and potential PCR inhibitors are removed with subsequent wash steps, and purified nucleic acid is eluted from the magnetic glass particles with elution buffer at an elevated temperature.Selective amplification of target nucleic acid from the sample is achieved by the use of target-specific forward and reverse primers provided by the customer. The cobas omni Utility Channel Master Mix Reagent 2 (UC MMX-R2), provided by Roche as part of the cobas omni Utility Channel Reagent Kit, includes an internal control. Selective amplification of the internal control is achieved by the use of sequence-specific forward and reverse primers that also are included in the UC MMX-R2 reagent. A thermostable DNA polymerase enzyme is used for both reverse transcription and PCR amplification. The master mix includes deoxyuridine triphosphate (dUTP), instead of deoxythimidine triphosphate (dTTP), that is incorporated into the newly synthesized DNA (amplicon).1,2,3 Any contaminating amplicon from previous PCR runs is eliminated by the AmpErase enzyme included in the master mix during the first thermal cycling step. However, newly formed amplicon is not eliminated since the AmpErase enzyme is inactivated once exposed to temperatures above 55°C.1. Longo MC, Berninger MS, Hartley JL.
