In an assay for endotoxin, if sample remains liquid:
|
|
It is incubated
|
|
|
It is free of endotoxins
|
|
|
It forms a clot
|
|
|
Endotoxins are present
|
Explanation:
Detailed explanation-1: -Endotoxin can be inactivated when exposed at temperature of 250º C for more than 30 minutes or 180º C for more than 3 hours (28, 30). Acids or alkalis of at least 0.1 M strength can also be used to destroy endotoxin in laboratory scale (17).
Detailed explanation-2: -Elimination of endotoxin contamination requires a combination of effective bacterial control via UV, chemical sanitization and optimal in line POU filtration. Positively charged filters provide the ideal means to remove final traces of endotoxin from ultra-pure water systems.
