Frequently Asked Questions (FAQs) About LAL Assay Accessories
Why would I use endotoxin-free test tubes?
Per the FDA, LAL assay best practices include control over the endotoxin levels of the equipment used in the preparation of the LAL assay.
When would I use endotoxin-free test tubes in endotoxin testing?
Endotoxin-free test tubes should be used when collecting samples that will be tested in the LAL assay.
Are pyrogen-free test tubes the same as endotoxin-free test tubes?
Pyrogen-free test tubes and endotoxin-free test tubes are not the same; Charles River sells endotoxin-free test tubes.
