Alcian Blue 1%, pH 2.5 Stain Kit

Stains acid epithelial mucin (sialomucin, sulfomucin) as well as stromal (mesenchymal) mucin. Hyaluronidase digestion step can be employed for further differentiation of acid epithelial from stromal mucin.

Part # 9102A 250ml kit $156.20  
Part # 9102B 500ml kit $199.80

Part # Non-Kit      

Alcian Blue/PAS Stain Kit

Differentiates between acidic epithelial mucins (sialomucin, sulfomucin) and neutral epithelial mucin and is a means of detecting the overall presence of mucins.  Acidic mucins are stained with the Alcian Blue technique while neutral mucins and glycogen are stained by the PAS reaction.

Part # 91022A 250ml kit $186.70  
Part # 91022B 500ml kit $335.50  

Colloidal Iron, Müller-Mowry Stain Kit

Stains acid epithelial mucin (sialomucin, sulfomucin) and stromal (mesenchymal) mucin and also demonstrates encapsulated yeast Cryptococcus neoformans.

Part # 9110A 250ml kit $283.10 H

Mucin, Mayer Mucicarmine Stain Kit

Stains acid epithelial mucin (sialomucin, sulfomucin) and is also useful for the demonstration of the encapsulated yeast Cryptococcus neoformans.

    • Microwave Modification Included


Part # 9151A 250ml kit $153.50 H
Part # 9151B 500ml kit $231.30 H

Periodic Acid Schiff (PAS) Stain Kit

Stains glycoproteins and aids in the differential diagnosis of tumors through the detection of acid/neutral epithelial mucins and/or glycogen. Digestion steps can be employed for further identification of mucosubstances.  Also useful for staining basement membranes and fungal cell walls.

Part # 9162A 250ml kit $204.10 H
Part # 9162B 500ml kit $282.80 H
