LOW ENDOTOXIN REAGENTS


Low Endotoxin Reagents

Procedure for making endotoxin free water: The regular tap water was filtered through 10-micron filter and carbon filter followed by flow through UV light and mixed bed resin. The final product was subjected to filter through mixed bed resin (Elga, Ultra-filtration cartridge, LC-169 and Labpure S5 cartridge) to remove any remaining endotoxins. Endotoxin level was determined in each batch of the above purified water by using an ultra-sensitive ToxinSensor spectrophotometeric method.
