There is no Product Information Sheet specific for product SE0027. There are other sodium heparin products from the porcine intestinal mucosa. The Product Information Sheet for H3393 states:
Storage/Stability: Store the powdered product at room temperature.
Heparin is a polysaccharide, which remains active in aqueous solution for up to 2 years at 2–8 °C, provided the solutions have been filtered through a 0.2 mm membrane. Alternatively, 0.06–1% benzyl alcohol may be added to solutions to prevent bacterial growth. Any trace of contaminating organisms in the solution will break down the heparin to use its sugars for nutrients, resulting in the degradation of non-sterile solutions.
Heparin solutions should not be autoclaved, because additional crosslinking of the sugars may occur at high temperatures. There is no need to freeze solutions of heparin; in fact, solutions of any polysaccharide of high molecular mass should not be frozen.
Other sources state that the pH should be between a range of pH 4 to pH 9.
