Grocott Methenamine Silver (GMS) Stain Kit is designed for the demonstration of fungal organisms and certain microorganisms in tissue sections. Based on the widely used silver impregnation method, this kit produces sharp black staining of fungal cell walls against a pale green background, providing...

For the highly sensitive detection of glycoproteins following gel electrophoresis (Figure 1) or protein transfer to nitrocellulose membranes (Figure 2). The kit uses an enhanced Periodic Acid-Schiff (PAS) method for detection of glycoprotein sugars. The supplied oxidizing agent first oxidizes the...

Used to examine metachromic granules in C. diphtheriae, screening bacteria in CSF, or for enumeration of fecal leukocytes.

Propidium iodide reagent is used for the fluorescent staining of nucleic acids. Propidium iodide (PI) binds to DNA by intercalating between the bases with little or no sequence preference and with a stoichiometry of one dye per 4-5 base pairs of DNA. PI also binds to RNA, necessitating treatment...

Decolorizer used in the gram stain procedure, intermediate 50% alcohol/50% acetone. Recommended for use with stabilized iodine.
