General description

Pyrase Strips are for enzymatic test for the detection of pyrrolidonyl peptidase (pyrase). Pyrase is an enzyme produced by all common species of Enterococci and by 98% of Streptococcus pyogenes strains. Detection of pyrase is a sensitive, reliable and rapid method of wide application. It is substantially more efficient than the bacitracine disc tests (Cat. No. 08382) used for the differentiation of S. pyogenes strains and the tests used for grouping of Enterococci. Strip can also be used for the identification of Gram-positive genera, catalase negative cocci, and coccobacilli.
The result of the reaction is read after 2 min.


Pyrase Strips are used for diagnostic test for the rapid differentiation of Enterococci from the group D Streptococci and differentiation of Streptococcus pyogenes from other haemolytic Streptococci.


50 test strips, 1.0 mL reagent


The kit contains plastic strips with a paper zone saturated with chromogenic substrate for the detection of pyrrolidonyl peptidase and a bottle containing a developing reagent.
