Microscopy and staining reagents
Avantor offers a broad line of reagent droppers, diagnostic kits, and antigens and antisera, for aid in identifying a variety of microscopic organisms. The visualization of bacteria by means of staining procedures is an important tool for any microbiologist to have at their disposal, and these carefully standardized and reproducible stain reagents help to ensure accurate and easily interpretable results. Stains are also available to provide early detection of positive blood cultures by fluorescence procedures.

Vectashield® mounting medium
Supplier: VECTOR LABORATORIES
Vectashield® Mounting Medium is a unique, stable formula for preserving fluorescence. It is superior to other anti-fading reagents or mounting media for fluorescence microscopy. Some agents retard the rate of fading, but their initial application gives a severe reduction in emission. Others give a good initial reading but bleach upon illumination. Vectashield® Mounting Medium combines both advantages into one product. It provides strong initial fluorescence and retards photobleaching over time. Vectashield® Mounting Medium is supplied in a bottle fitted with a cone-seal cap. A cap fitted with a drop dispenser pipette is also included. The cone-seal cap can be replaced with the drop dispenser cap for routine use and during storage. Mounted slides should be stored at 4 °C. The fluorescence will remain for many weeks.

Zinc Formalin Fixative
Supplier: SIGMA ALDRICH MICROSCOPY
Zinc formalin fixative is a non-precipitating fixative. This fixative is compatible with histochemical, immunochemical and special stains. It may be used with automated tissue processors and also in manual methods. The zinc chloride component of the formulation increases the rigidity of cellular components to withstand subsequent processing, sectioning and staining procedures. Tissue specimens initially fixed using 10% neutral buffered formalin solution may be post-fixed using the zinc formalin fixative.
