Leukopoïesis - DIFF Cytochemistry reaction + Chlorazol Black • Lyses of RBC • Stabilises Leukopoïesis - DIFF Cytochemistry reaction + Chlorazol Black • Lyses of RBC • Stabilises the WBC's in their native forms • Differentially stains the leukocytes. Staining intensity is proportional to the nucleic acid quantity, to the maturity of this nucleic acid, to the lipids and enzyme quantity. The absorbance measurement is then proportional to the stain intensity.
