KREX® Technology

  • All proteins are full-length, correctly folded, and functional.
  • Conformational epitopes are preserved, ensuring specific, biologically-relevant binding.
  • Each protein is printed in the same orientation relative to the slide surface, resulting in exceptionally high reproducibility.
  • Propriety surface chemistry and storage buffer allow the proteins to maintain tertiary structure and behave as if in free solution.
  • Glass slide-based format.
  • Each protein printed in technical quadruplicate.
  • Fluorescence readouts for high sensitivity assays.
  • Profile hundreds to thousands of proteins in a single sample.
