It is advised to check the references for photos of reaction results. [1] Reagent testers might show the colour of the desired substance while not showing a different colour for a more dangerous additive. [2]
The use of podiatry drills, in the absence of engineering controls and personal protective equipment, is an occupational hazard to the healthcare provider.Nail dust collected during foot care procedures performed in office settings has been found to contain keratin, keratin hydrolysates, microbial debris, and viable fungal elements, including dermatophytes (most commonly Trichophyton rubrum ...
Most recipes produce red keratin and muscle fibers, blue or green collagen and bone, light red or pink cytoplasm, and dark brown to black cell nuclei. The trichrome is applied by immersion of the fixated sample into Weigert's iron hematoxylin, and then three different solutions, labeled A, B, and C:
Blue nucleus, blue cytoplasm, red granules Basophils: Purple/dark blue nucleus, violet granules Monocyte: Violet nucleus, light blue cytoplasm Bacteria and fungi: Dark blue Cytoplasm, collagen and muscle: Various shades of pink, orange, yellow and blue [11] Spermatozoa: Light blue acrosomal region, dark blue post-acrosomal region [8]
These aldehydes then react with the Schiff reagent to give a purple-magenta color. A suitable basic stain is often used as a counterstain. • PAS diastase stain (PAS-D) is PAS stain used in combination with diastase, an enzyme that breaks down glycogen. • Alcian blue/periodic acid–Schiff (AB/PAS or AB-PAS) uses alcian blue before the PAS step.

These structures contain many positive charges and are thus strongly stained by anionic dyes like eosin. A typical combination of basophilic and eosinophilic dyes is the H&E stain, which visualizes basophilic structures in blue and eosinophilic structures in red. [1]
