You have goals for every project, and your CRO should be as committed to those goals as you are. But if things take too long to get done, it might be time to switch CROs instead. Learn to spot these six signs your preclinical work needs a new CRO.

CT26 SC tumors: Gating strategy T cells and NK cells.
Gating involved identifying the total cell population, and then gate out the doublets, gate out the dead cells, move on to our first marker CD45 which gates out any non-immune cells. The bottom right cytogram shows the different NK cell populations. The far left middle cytogram depicts the two T cell population CD4+ and CD8+. Values are % of total CD45+ cells.
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.
