SIGMA SP™ is a novel reagent for sputum sample collection. It is available in ready to use liquid format for the rapid liquefaction of sputum specimens in preparation for inoculation on automated platforms or by manual methods.

The reagent has a more powerful mucolytic activity than dithiothreitol, but is also ready to use in a neutral pH solution that is stable at ambient temperature and requires no special storage conditions.

Sigma-SP™ in ready to use format is particularly suited for use on automated platforms. The tubes and caps are completely compatible with most platforms currently in use.
