You are right! Thank you for correcting me.
Surely sialomucins will be positive for PAS and H.acid will be negative?

The hyaluronidase is digesting out hyaluronic acid, a component found in connective tissue mucins. This reaction is used to differentiate connective tissue mucins from epithelial mucins. Hyaluronic acid and epithelial sialomucins will give the same staining results, both positive for alcian blue pH 2.5 and negative for pH 1.0. -----Original Message----- From: Hobbs, Carl via Histonet <[email protected]> Sent: Thursday, August 23, 2018 11:32 AM To: histonet <[email protected]> Subject: Re: [Histonet] Alcian Blue digested w Hyaluronidase - any alternatives? Perhaps Alcian blue at pH3 ( all acidic mucins) on one slide/section and Ab pH1 ( highly sulphated mucins only) on a sequential slide? Sure, instead use Alcian blue CEC method? I will be interested to read other responses to your request.
