The chondrogenic differentiation potential was examined using a pellet culture, with the pellet size monitored and the degree of alcian blue

The stomach contents were immersed immediately in 10 ml of 0.02% Alcian blue
in 0.16 M sucrose/0.05 M sodium acetate, pH 5.8, and incubated for 24 h at 20 [degrees]C.
Next, we performed Alcian blue
and Sirius red staining for cartilage proteoglycan collagen, respectively.
Depletion of intestinal goblet cells was observed in 10 cases of PCV2 IHC-stained sections of colon counterstained with Alcian blue
The results of alizarin red, oil red O, and alcian blue
stainings showed that osteogenic, adipogenic, and chondrogenic differentiations of BMSCs were all enhanced in the DRG+ BMSC group, compared with the BMSC group (Figure 2(c)).
The edematous stem villous stroma stains for Alcian blue
, but is negative for smooth muscle actin, which shows positive staining of normal villous stroma.
On special stain (alcian blue
) there was some mucin deposition in areas of degenerated collagen.
Silver staining combined with alcian blue
and hematoxylin-eosin for the detection of Lawsonia intracellularis in swine proliferative enteropathy.
After routine histological methods, 5 [micro]m sections were obtained and coloured by Gomori's trichrome, periodic acid-Schiff (PAS), Alcian Blue
pH 2.5 and pH1.0, acetylation + PAS, acetylation + deacetylation + PAS, acid hydrolysis + PAS, phenylhydrazine + PAS and thiosemicarbazide + PAS.
The sections were first cleared of paraffin using xylene and rehydrated in gradients of alcohol and then stained with Alcian blue
(Sigma) in 3% acetic acid; the sections were then stained with Alcian blue
and then dehydrated with 95% ethyl alcohol, 100% ethyl alcohol, and xylene.
The staining currently automated are: Massons~s trichrome (or Gomori~s trichrome), Grocott~s Methenamine Silver (or Gomori~s Methenamine Silver), Giemsa, Gordon and Sweet (or Gomori and Snook), Congo Red, Jones Methenamine Silver (with H&E contrast colour), Gram, PAS + diastase (2 kit), Perls Prussian Blue, Alcian Blue
(pH 2,5), Ziehl-Neelsen, Elastin (Modified Weigert~s Resorcin Fuchsin, Verhoeff~s elastic tissue).
