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.  This answer may also be found on the product detail page. http://www.sigmaaldrich.com/catalog/search/ProductDetail/SIAL/H3149
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.
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. The answer can also be found by clicking: http://www.sigmaaldrich.com/etc/medialib/docs/Sigma-Aldrich/Product_Information_Sheet/h3149pis.Par.0001.File.tmp/h3149pis.pdf

Please see the following link that describes the change in the USP monograph: http://www.usp.org/usp-nf/hot-topics/heparin/official-stage-2-monographs
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.
How much Heparin sodium salt, is used to prevent coagulation?
We suggest using 20 to 50 units per mL of blood.  
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.  
What concentration of Heparin sodium salt, can I use to inhibit RNAse activity?
What concentration can I use to inhibit RNase activity?" Change answer to: "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).
