The pHast technology is one of our fastest tools for quantitative testing of your material’s specificity, binding, and internalization, providing results in 1 day. pHast products bind to your material via a secondary antibody or Streptavidin cross-linked to a pH-dependent fluorescent reporter. This fluorescent reporter increases intensity as the pH of its surroundings becomes more acidic, as evident when exposed to the environment inside a cell. A successful assay will provide an EC50 by way of a fluorescence detecting plate reader, illuminating your lead candidates.
