Product Description


Product Description

Periodic acid is an oxidizer. The reaction of periodic acid oxidizes the vicinal diols in some sugars such as glycogen, glycoproteins, glycolipids and mucins, usually breaking up the bond between adjacent carbons and creating a pair of aldehydes at the two free tips of each broken monosaccharide ring. The exposed aldehydes can be stained by magenta and generate red to purple red complex, which is a position mark.

Notes

1 The periodic acid solution should be stored in 4℃

2 The Schiff reagent should be stored at 4℃ avoiding light and reach its room temperature before use. The Schiff reagent can be recycled and reused for many times. When it turns pink, it is unusable.

3 The staining time of Schiff reagent depends on room temperature. Shorten the staining time when room temperature is high (e.g. in summer), and extend it to about 60 min when room temperature is low (e.g. in winter).
