Here we describe a system that incorporates thermal stability screening into formulation design using heat labile measles virus as a prototype.
This approach of high‐throughput thermal and colloidal stability screening can be applied to the characterization and prediction of protein formulation properties.
The mutations enforced a cumulative exact 3-fold symmetry upon symmetrically equivalent positions within the protein and were combined with a stability screen.
In this report, we introduce an efficient microscale fluorescent stability screen using the thiol-specific fluorochrome N-[4- 7-diethylamino-4-methyl-3-coumarinyl phenyl]maleimide N-[4- 7-diethylamino-4-methyl-3-coumarinyl phenyl]maleimide N-[4- 7-diethylamino-4-methyl-3-coumarinyl phenyl]maleimide N-[4- 7-diethylamino-4-methyl-3-coumarinyl phenyl]maleimide N-[4- 7-diethylamino-4-methyl-3-coumarinyl phenyl]maleimide N-[4- 7-diethylamino-4-methyl-3-coumarinyl phenyl]maleimide N-[4- 7-diethylamino-4-methyl-3-coumarinyl phenyl]maleimide N-[4- 7-diethylamino-4-methyl-3-coumarinyl phenyl]maleimide
We also present a new stability screening method in a 96-well assay format to quickly identify evolved receptors showing increased thermal stability in detergent-solubilized form and rapidly evaluate them quantitatively.
A much earlier study by Zoglio, et al. highlighted the usefulness of the LNISO method in stability screening of drugs in different pharmaceutical formulations (Zoglio et al. 1968).
The LNISO method allows for stability screening of a greater number of drug candidates in a short period of time during preformulation at the discovery and development interface.
At the discovery and development interface, the use of t90% values to establish binning classifications for stability screening is considered adequate, since it most often represents the outer limit of the stability.
Finally, all three of the stability screening methods binned Compounds A4 and A12 into BIN 3, which is the category for compounds with predicted t90% values less than 12 months.
All three of the stability screening methods binned nine of the 18 compounds (A1, A2, A5, A6, A8, A10, A14, A15, and A17) into BIN 1, which is the category for compounds with predicted t90% values greater than 24 months.
