Description
- For intestinal protozoa
- Kit contains 100 mL of each Solution
- Not to be confused with Gomori's Trichrome Stain used for Histology
- PVA Solution, when mixed with liquid stool specimens, (3-4 drops PVA with 1-2 drops of fecal material on a slide) provides excellent adhesion of specimen to slides, if allowed to dry several hours at 35°C or overnight at room temperature
- Schaudinn fixative will properly fix and hold fresh stool specimens that have been thinly spread on a slide (5 minutes at 50°C or 1 hour at room temperature)
- Smears may be left in fixative for several hours or 1-2 days without harm
- PVA fixative (a combination of PVA Solution and Schaudinn's fixative) will adhere as well as preserve organisms and prevent their loss during staining
- One distinct advantage of PVA fixative is that it makes possible the successful staining of organisms in liquid specimens.
