Esterases are ubiquitous in nature and encompass a series of different enzymes acting upon select substrates.


  • Suitable for haematology
  • Suitable for histology


According to the methodology, a-naphthyl acetate is enzymatically hydrolysed, liberating a free naphthol compound. This then couples with a diazonium compound, forming black coloured deposits at sites of non-specific esterase activity. This enzyme is detected primarily in monocytes, macrophages and histocytes, and is normally absent in granulocytes.


Lymphocytes may occasionally exhibit enzyme activity. A sodium fluoride inhibition procedure may be run to demonstrate monocyte inhibition. The procedure is run at 37 °C and may be utilized with blood, bone marrow films, tissue-touch preparations, cytocentrifuge preparations and frozen sections. The enzyme does not survive paraffin processing.
