Research use only
Materials are offered to qualified researchers aged 21 or older for in vitro laboratory research. They are not for human or veterinary use, personal use, or dietary supplementation.
Our approach
Clear information.
Informed research.
Know the compound, the amount, and the documentation attached to it.
Product details
Product names, amounts, and prices are presented together so you can compare available variants.
Certificates of analysis
Available certificates of analysis are linked by compound and reported amount. Each report describes its identified sample and lot. Compare those details with the product documentation.
How to read a Certificate of Analysis
Match the sample
Compare the compound, amount, lot number, and report date with the material's documentation. Results describe the sample identified in that report.
Read the result and its units
The nominal amount identifies the sample as labeled. An assay reports a measured result. Read the method, units, and specification together; mg per vial and mg/g are different measurements.
Check what was tested
Identity, purity, assay, sterility, and endotoxins are separate tests. A purity percentage alone does not establish sterility or endotoxin levels. Use only the tests and results actually reported.
