Questions

  1. Hi, I´m Laura. I´m wondering if you can bring me the document where is indicated the preparation for this strain, please. I have the information that it can be prepared like the conventional eosin strain, but I want to be sure. Thank you so much.

    1. Unfortunately, neither preparation instructions nor a protocol are offered for this product. This product is approximately 90% Erythrosin B and 10% Eosin Y. The solubility is tested at 10 mg/mL in water. See the link below to the Histonet archives. Several references are found there when searching for 'erythrosin and eosin stain'.
