Q: What is Control Standard Endotoxin (CSE)?
Control Standard Endotoxin (CSE) is a purified preparation of endotoxin (typically Escherichia coli) used as a reference standard in LAL (Limulus Amebocyte Lysate) testing to calibrate lysate sensitivity and prepare standard curves.
Q: How do I choose between CSE01, CSE02, and CSE03?
The choice depends on the sensitivity of your LAL assay. CSE01 (1 to 100 EU/vial) is suitable for low-range assays, CSE02 (100 to 1000 EU/vial) is ideal for standard ranges, and CSE03 (1000 to 10000 EU/vial) is designed for high-concentration applications and dilutions.
Q: What is the packaging size for these catalog numbers?
All three catalog options (CSE01, CSE02, and CSE03) are supplied in a standardized package containing 10 vials per pack.
Q: Why is the potency of CSE expressed as a range?
The exact potency of CSE is lot-specific and is calibrated against the Reference Standard Endotoxin (RSE). The indicated range provides the typical potency expectation for each catalog number prior to lot certification.
Q: How should the CSE vials be stored?
Unreconstituted CSE vials should be stored at 2-8°C. Once reconstituted, storage conditions depend on the assay protocol, but they are typically kept refrigerated and should be thoroughly vortexed before use.
