Descripción general

Heparin is mainly responsible for the delay in the coagulation of blood. It enhances the antithrombin-mediated inactivation of proteases in the coagulation pathway.

Aplicación

  • Heparin sodium salt from porcine intestinal mucosa has been used in sLRP (soluble circulating low density lipoprotein receptor-related protein-1) purification from human plasma.
  • It has been used as a supplement in M199 medium for culturing of human umbilical vein endothelial cells.
  • It has been used as an anticoagulant agent during isolation of blood.

  1. How is Heparin sodium salt from porcine intestinal mucosa, Product H3149, solubilized?

    Heparin sodium salt from porcine intestinal mucosa is soluble in deionized water at a concentrationi of 50 mg/mL.

  2. How much of Heparin sodium salt from porcine intestinal mucosa, Product H3149, is used for cell culture?

    Solutions at 0.5 mg per mL were tested in cell culture. Start at this concentration, and titer from there to determine the optimal concentration for usage.

  3. How are solutions Heparin sodium salt from porcine intestinal mucosa, Product H3149, stored?

    Solutions can be stored at 2-8C for up to 2 years, if sterile filtered through a 0.22 micron filter. Benzyl alcohol (0.06-1%) can be added to solutions to prevent microbial growth.

  4. How many milligrams of Heparin sodium salt, Product H3149, are in the bottle?

    The potency, in units/mg, is lot-specific; the value can be found on the certificate of analysis. It is typically over 140 units per mg. The number of milligrams can be calculated by dividing the number of units by the potency in units per mg.

  5. 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.

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

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

  7. 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.  

  8. 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).

  9. 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.

  10. 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.
