Which granules can be stained with azure B and eosin?

Area of Science:

• Hematology
• Cell Biology
• Histology

Background:

• Conventional Romanowsky-Giemsa stains show fine granules in neutrophilic leukocytes.
• Wittekind's standardized stain reveals coarser granules, indicating distinct granule populations.

Purpose of the Study:

• To investigate the differential staining of neutrophil granules using Wittekind's method.
• To compare Wittekind's stain with conventional methods for granule identification.

Main Methods:

• Analysis of unbiased peripheral neutrophil samples.
• Multivariate analysis of granulation patterns.
• Comparison with specifically stained primary granules.

Main Results:

• Wittekind's stain clearly visualizes primary granules in neutrophils.
• Secondary granules exhibit enhanced dye uptake with Wittekind's method.
• Granule staining characteristics correlate with leukocyte count.

Conclusions:

• Wittekind's stain differentiates neutrophil granule classes more effectively than conventional methods.
• Identification of granule classes requires multivariate analysis, not single granule morphology.
• Staining behavior is linked to leukocyte count, suggesting diagnostic potential.
