If you’re looking for an expert team to guide your trial with efficiency in mind, we can help. As the creators of the Dynamic Trial, TD2 provides start-to-finish support with trial strategy, design and execution for faster go-to-market potential.
Screening tools for the evaluation of a drug’s ability to cross various biological membrane systems in a microplate format.
Figure 7. Example of Caco-2 Assay results. Assessment of the permeability of either Metoprolol (highly Permeable) or Quinidine (PgP substrate). A cell monolayer grown on a filtered-well is used to evaluate test compound movement between the insert (apical compartment -A) and the plate well (basal compartment -B). Passive transport through the layer is determine by A-B flux, whereas active transporter will introduce a B-A distribution of compounds between the two compartments.
In vitro drug metabolism studies, are a screening mechanism to characterize drug metabolites, elucidate their pathways, to help with further in vivo testing.

(Ketoconazole) and the substrate (Midazolam).

Protein binding assays assesses the degree to which drugs attaches to proteins within the plasma/tissue. A drug’s efficacy may be affected by the degree to which it binds. TD2 has validated this assay using the Rapid Equilibrium Device and analysis done by LC-MS.
