what is used for a coagulase test
The coagulase tube test has been set up as a demo for you to observe in class. This version of the coagulase test is used to identify the presence of either bound coagulase or free coagulase, which is an extracellular enzyme.Free coagulase reacts with a component of plasma called coagulase-reacting factor.The result is to cause the plasma to coagulate. In the demo, the coagulase plasma has been inoculated with Staphylococcus aureus and Staphylococcus epidermidis and allowed to incubate at 37ËC for 24 hours.ound coagulase reacts with the fibrinogen in plasma, causing the fibrinogen to precipitate. This causes the cells to agglutinate, or clump together, which creates the âlumpyâ look of a positive coagulase slide test.
