Thermo Scientific™ TB Digestant

Description

• Digest and decontaminate clinical specimens prior to inoculation of media for isolation of Mycobacterium species with Thermo Scientific™ Remel™ TB Digestant
• Respiratory specimens such as sputum contain mucin, which traps microorganisms
• Such specimens require liquefaction to release the mycobacterial cells prior to inoculation of media
• The N-acetyl-L-cysteine (NAC) method is the widely used procedure for digestion and decontamination of specimens for recovery of Mycobacterium spp 1
• TB Digestant has also been used successfully in Petroff's sodium hydroxide digestion method 2
• The majority of clinical specimens submitted to the microbiology laboratory for isolation of acid-fast bacilli are contaminated with more rapidly growing commensal microbial flora
• TB Digestant decontaminates the specimen by reducing or eliminating commensal microbial flora and digests respiratory secretions, releasing mycobacterial cells for detection in stains and cultures
• Ready-to-use – Liquid reagent supplied in 250mL bottle Easy-to-store – Store at room temperature until used TB Digestant contains 4% sodium hydroxide (CAS 1310-73-2) in demineralized water (CAS 7732-18-5)
• Specimens should remain in contact with the decontaminating solution for no longer than 15 minutes
• Overprocessing may result in reduced recovery rates of Mycobacterium spp 2
