Product Type Homogeneous Membrane Integrity Assay

Cell viability is most often defined based on the integrity of the cell membrane. Measuring leakage of components from the cytoplasm into the surrounding culture medium is widely accepted as a valid method to estimate the number of nonviable cells.

  • Rapidly measures the release of lactate dehydrogenase (LDH) from cells with a damaged membrane, while leaving cells intact
  • Assay can be completed in a single 96- or 384-well plate without separating cells from supernatant
  • Enables multiple homogeneous cell-based assays to be performed on a single sample
  • Versatile protocol allows assays to be read over several hours or after 10-minute incubation
  • HTP Assay offers convenient, alternate packaging for processing multiple plates; each bottle of reagent is sufficient to perform 500 assays in a 96-well format or 2000 assays in a 384-well format

Cytotoxicity determination; total cell number determination
