Residual Solvents: The Class 3 solvents Ethanol, Isopropanol, Ethyl
Acetate and the Class 2 solvent Methanol are likely to be present. These solvents are quantified and reported on each batch. No other
Class 1,2,3, or other solvents are used or produced in the production
process. Dioxane was not used in the manufacturing process.
Bacterial Induction characterization: Test performed at 1 mM of IPTG (E.
Coli. protein expression)
IPTG is highly hygroscopic. Allow packaging/container to equilibrate to
room temperature before opening for analysis. Ensure sample is kept dry
(such as in a desiccator) after opening.
