  1. How does the storage temperature relate to shipping conditions?

    The storage conditions that a Sigma-Aldrich catalog and label recommend for products are deliberately conservative. For many products, long-term storage at low temperatures will increase the time during which they are expected to remain in specification and therefore are labeled accordingly. Where short-term storage, shipping time frame, or exposure to conditions other than those recommended for long-term storage will not affect product quality, Sigma-Aldrich will ship at ambient temperature. The products sensitive to short-term exposure to conditions other than their recommended long-term storage are shipped on wet or dry ice. Ambient temperature shipping helps to control shipping costs for our customers. At any time, our customers can request wet- or dry-ice shipment, but the special handling is at customer expense if our product history indicates that the product is stable for regular shipment. See Shipping and Storage for more information.

  2. What is the molecular weight of Heparin sodium salt?

    Heparin is a mixture of polyanion chains having molecular weights ranging from 6,000 to 30,000 Daltons, with most chains in the range of 17,000 to 19,000 Daltons.

  3. How much Heparin sodium salt, is used to prevent coagulation?

    We suggest using 20 to 50 units per mL of blood.

  4. What is the best way to sterilize Heparin sodium salt?

    Although solutions may be autoclaved at 121 °C for 5 to 10 minutes, we generally recommend sterile filtration. This is because prolonged autoclaving may have an effect on its activity.  

  5. What concentration of Heparin sodium salt, can I use to inhibit RNAse activity?

    Heparin has been used at concentrations ranging from 100 to 500 μg/mL. This has been reported in the J. Biol. Chem., 248, 2095 (1973).

  6. Which document(s) contains shelf-life or expiration date information for a given product?

    If available for a given product, the recommended re-test date or the expiration date can be found on the Certificate of Analysis.

  7. How do I get lot-specific information or a Certificate of Analysis?

    The lot specific COA document can be found by entering the lot number above under the "Documents" section.

  8. How do I find price and availability?

    There are several ways to find pricing and availability for our products. Once you log onto our website, you will find the price and availability displayed on the product detail page. You can contact any of our Customer Sales and Service offices to receive a quote.  USA customers:  1-800-325-3010 or view local office numbers.

  9. What is the Department of Transportation shipping information for this product?

    Transportation information can be found in Section 14 of the product's (M)SDS.To access the shipping information for this material, use the link on the product detail page for the product. 

  10. What is the pH of a 1% solution of Product H4784, Heparin sodium salt?

    The pH of 1% solution of heparin sodium salt is typically in the range of 6.0 to 7.5.

  11. What concentration of Product H4784, Heparin sodium salt, is used in cell culture for the cultivation of human epidermal melanocytes in absence of phorbol esters?

    Heparin is used at a concentration of 1 ng/mL, according to Picot, J., Human Cell Culture: Methods in Molecular Medicine, 2nd ed., (Humana Press Inc., 2005) pp. 13-28.

During development, many mutations cause increased variation in phenotypic outcomes, a phenomenon termed decanalization. Phenotypic discordance is often observed in the absence of genetic and environmental variations, but the mechanisms underlying such inter-individual phenotypic discordance remain elusive.
