Technical Data Sheet #740
TB Processing Reagents
NALC + Digestant Kit .......................................................
Sputum decontamination reagents are used to break down mucous components of sputum and
other clinical specimens and to decontaminate the specimen of normal flora in order to allow
slower growing mycobacteria to grow. The recovery of mycobacteria from sputum or other mucous
containing specimens contaminated with other organisms is difficult, since mycobacteria generally
grow much slower than other bacterial species. Decontamination and digestion of the mucous
components kills contaminating normal flora and allows slower growing mycobacteria to grow.
Sodium hydroxide (NaOH), in the TB Base Digestant, acts as an emulsifier and a decontaminant,
breaking down mucoid material and inhibiting the growth of contaminants. Sodium citrate, in
the TB Base Digestant, aids in the liquification by binding heavy metals, thus stabilizing N-Acetyl-
L-Cysteine (NALC) and allowing it to work properly N-Acetyl-L-Cysteine (NALC), when combined
with Sodium hydroxide (NaOH), facilitates decontamination by further digesting mucopurulent
specimens which allows the NaOH to penetrate. 5 NALC/5 Digestant. Store at 2-8°C.
