Can Poly-HRP Streptavidin (Cat. No. N200) be stored at -80 degrees C to increase its shelf life?

We do not recommend storing Poly-HRP Streptavidin at -80 degrees C, as the product can freeze solid at temperatures below -25 degrees C even if it has 50% glycerol as a stabilizer, thereby necessitating thawing of the product. With multiple freeze-thaws, the enzyme conjugates are rendered unstable.
