Haemalum (Mayer's), Sigma-Aldrich®
Supplier: Merck
In hematoxylin-eosin staining (H&E), the most widely used histological staining technique, nuclear staining is achieved using ready-to-use staining solutions, such as Mayer’s hemalum solution or Hematoxylin solution modified according to Gill III. These solutions do not need to be filtrated prior use and the dye is oxidized in a controlled manner, which renders the results robust and allows a brilliant differentiation of the stained structures. Counterstaining of i.e. for proteins, collagen, keratin, intercellular substances. can be performed with alcoholic or aqueous Eosin Y solution 0.5 %. It is registered as IVD and CE certified product and can be used for clinical diagnostics.

Dehydrated culture media, TOS-propionate agar (base)
Supplier: Merck
In combination with the selective supplement Lithium-Mupirocin (MUP) the TOS Propionate agar allows the direct detection of viable bifidobacteria in starter cultures and various milk products like fermented and unfermented milk, milk powder and baby food. The growth of other lactic acid bacteria is very much inhibited so that a confirmation of presumptive bifodobacteria is in most cases not necessary.
