Sed-Fix Concentrate and Working Solution
Sed-Fix is a preservative and fixative containing polyethylene glycol. Sed-Fix can be mixed with equal parts of cell suspensions from all body sites.
For maximum cell recovery, cell spreads should be air dried, the shrinkage being minimized by the precipitated polyethylene glycol. Following air drying, the cell spreads should be immersed for ten minutes in 95% ethanol to thoroughly remove the polyethylene glycol.
Sed-Fix is available in a liquid concentrate to make one gallon and a ready-to-use working solution.
