5.0 PROCEDURE
5.1
Take the sample (product diluted to 2-fold of MVD) 50
 l each in endotoxin free tubes by micropipette fitted with disposable tip. Keep all the sets in duplicate for product positive and product negative.
5.2
Add 50
 l of reconstituted Control Standard Endotoxin diluted to 2

in positive tubes and 50
 l of LAL reagent water in negative tubes.
