Models for the preliminary stages of toxicity testing

Modeling, screening, and characterizing candidate therapeutics happens at a rapid pace. Drug development scientists need to be able to screen an astronomical number of these biological and chemical entities to eliminate all but a few strong candidates for further interrogation. ATCC can get you started on the path to success in the preclinical arena with our complete solution of continuous cell lines, growth reagents, and cell viability assays.

  • Continuous Cell Lines – Eliminate large numbers of chemical entities by using high- throughput screening. ATCC offers authenticated cell lines from all physiological systems of the body.
  • Cell Growth Reagents – We offer uniquely formulated media, sera, and reagents to virtually guarantee successful cell culture.
  • Cell Viability Assays – Track the effects of a prospective compound by using an ATCC Cell Proliferation Assay kit. These assays are convenient, easy-to-use, and measure viability and growth.
