H. Justicia et M. Ibanez, AN APPROACH TO THE DETERMINATION OF ENDOTOXIN IN ANESTHETICS AND ANTIBIOTICS - USE OF AN ULTRAFILTRATION SYSTEM AND ENZYMATIC LAL REACTION, Journal of parenteral science and technology, 47(5), 1993, pp. 205-210
An ultrafiltration system is used to obtain an endotoxin-free buffer f
or the LAL test. The procedure is combined with a kinetic LAL reaction
of high sensitivity. This approach allows for the easy determination
of endotoxin levels in parenterals with LAL-interfering substances, re
ducing the maximum valid dilution necessary for use in product develop
ment.
