Control Standard Endotoxin (CSE)
KEY FEATURES
Can be used to prepare controls and standard curves
CSE power supplied to match each batch of LAL
Reconstituted CSE can be stored at 2–10°C for 1 month
PROCESS
Note: When tested with the Limulus Color KY series, the potency is shown on the CSE vial label. Divide the potency (EU/vial) by 1,000 to calculate the volume of LRW needed to reconstitute CSE for a yield of 1,000 EU/mL.
HOW SHOULD THE DILUTION BE PREPARED FOR THE GEL CLOT ASSAY?
Example: Labeled Sensitivity (λ) of PYROSTAR™ ES-F Multi-Test Reagent: 0.015 EU/mL
The final endotoxin (dilution tubes 8, 9, 10 and 11) would be achieved to generate a standard of dilutions to assess labeled sensitivity of 0.015 EU/mL.
Note: This is an example of how to perform the double dilution. It is acceptable to adjust the volumes of LRW and endotoxin if the ratios are maintained.
