The test for confirmation of lysate sensitivity would be to be carried out any time a new batch of LAL Reagent is used or when There may be any transform from the experimental problems which will have an affect on the result in the test.
It is difficult to remove endotoxins from products after existing. It is much much better to maintain completed products and solutions and parts relatively endotoxin-free rather then have to get rid of it as soon as existing.
Our full and optimized portfolio of extremely exact and responsible LAL and rCR formulations present amplified sensitivity, larger linearity, and excellent interference resistance.
