A method for the enumeration of micronucleated erythrocyte populations while distinguishing platelet and platelet-associated aggregates involves the use of a first fluorescent labeled antibody having binding specificity for a surface marker for reticulocytes, a second fluorescent labeled antibody having binding specificity for a surface marker for platelets and a nucleic acid staining , dye that stains DNA (micronuclei) in erythrocyte populations.

Why it's free to use

  • Filed June 28, 2004 and granted November 13, 2012. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended June 28, 2024.
  • A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by June 28, 2026.
  • We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
