UND 363 Alcian Blue 1.0
Question | Answer |
---|---|
What gives the blue color of alcian blue | copper |
Is alcian Blue an acidic or basic dye | basic dye |
At 2.5 ph what are stained with alcian blue | carboxylated and sulfated acid mucosubstances |
At PH 1.0 what are stained with alcian blue | ONLY sulfated acid mucosubstances are stained |
What is used in conjunction with alcian blue to differientated epithelial and connective mucin | hyaluronic acid (which preceeds the alcian blue staining in the process) |
what mucin will alcian blue not stain | NEUTRAL mucins |
Purpose of AB 1.0 | Demonstrate sulfated/sulfanated mucosubstances |
principle of AB 1.0 | uses 1.0 N HCL to stain ONLY sulfated acid mucopolysaccharides and sulfated sialomucins (glycoproteins) |
fixatives for AB 1.0 | 10% NBF or Bouins |
thickness and control | 4-5micron, sm. intestine, appendix, or colon |
microscope for AB 1.0 | Light |
Name the 3 major reagents with AB 1.0 | 0.1 N HCL, 1% alcian blue ** are combined** (stain mucin), nuclear fast red (counterstain) |
What are the expected results for AB 1.0 | sulfated mucosubstances - pale blue background/nuclei will be - pink to red |
