Quite a few parenteral drug products can be employed for your LAL test just after dilution with endotoxin-totally free distilled drinking water or an aqueous Remedy on the affliction that dilutions not exceed the utmost legitimate dilution. In 1973, Nachum et al. evaluated cerebrospinal fluid (CSF), which has extremely minimal protein content as compared to blood, using the LAL test as a possible Software to detect GNB meningitis.
Protocols need to evaluate the source of endotoxins used in the study, bearing in your mind that purified bacterial endotoxins could possibly respond in another way from indigenous sources of endotoxins.
Publishing on IntechOpen lets authors to earn citations and locate new collaborators, which means more and more people see your do the job not merely from the own discipline of review, but from other similar fields much too.
