"Grade I-A" originates from product listings for heparin prior to the implementation of the current catalog numbering system. This older grading system has since been phased out, but the terminology was retained in the descriptions of some current products. The M-Clarity™ Program accurately defines the current quality classification system, along with specifications listed in the product Specification Sheet and/or Certificate of Analysis.

General description
Heparin is a glycosaminoglycan (GAG) belonging to the mucopolysaccharides family, known for its potent anticoagulant properties. This extensively sulfated polysaccharide consists of D-glucosamine and hexuronic acid linked via glycosidic linkages. It finds wide application in biochemical research and cell culture studies.
Application
Heparin sodium salt from porcine intestinal mucosa has been supplemented in the medium prepared for insemination of oocytes with spermatozoa. Heparin sodium salt from porcine intestinal mucosa has been used:
- to check the effect of heparin on FGF21 (fibroblast growth factor 21) signaling.
- in immunostaining of mice brain sections
- to quantify white blood cells and red blood cells in Sparus aurata blood samples
- in anticoagulation and severe acute respiratory syndrome coronavirus 2 (SARS-CoV2) inhibition assay
Biochem/physiol Actions
Heparin is mainly responsible for the delay in the coagulation of blood. It enhances the antithrombin-mediated inactivation of proteases in the coagulation pathway.
Heparin is synthesized in mast cells and mediators such as histamine and is associated with allergy and inflammatory activity. Heparin shows therapeutic effects against venous thrombosis and pulmonary embolism, helps in preventing re-thrombosis post thrombolysis, and manages arterial thrombosis in patients who suffer from acute myocardial infarction. Heparin shows anti-inflammatory action in many inflammatory conditions such as burns, bronchial asthma, and ulcerative colitis.

Heparin for diagnostic manufacturing is available as product number SRE0027
Heparin solutions should not be autoclaved as additional crosslinking of the sugars may occur at high temperatures. It should not be frozen as well.

How can I determine the shelf life / expiration / retest date of this product?
1 answer-
If this product has an expiration or retest date, it will be shown on the Certificate of Analysis (COA, CofA). If there is no retest or expiration date listed on the product's COA, we do not have suitable stability data to determine a shelf life. For these products, the only date on the COA will be the release date; a retest, expiration, or use-by-date will not be displayed.
For all products, we recommend handling per defined conditions as printed in our product literature and website product descriptions. We recommend that products should be routinely inspected by customers to ensure they perform as expected.
For products without retest or expiration dates, our standard warranty of 1 year from the date of shipment is applicable.
For more information, please refer to the Product Dating Information document: https://www.sigmaaldrich.com/deepweb/assets/sigmaaldrich/marketing/global/documents/418/501/product-dating-information-06-25-mk.pdfHelpful?

How do I calculate how much Heparin sodium salt I need to prevent coagulation in a gallon of cow's blood? Would it have to be dissolved in a saline solution first?
1 answer-
The typical dosage of heparin for anticoagulation can vary based on the specific application and the type of blood product. For general anticoagulation, a common range is between 5 to 30 units of heparin per milliliter of blood. For cow's blood, the amount of this product needed will depend on the desired dosage and the volume of blood, which may be found in veterinary guidelines or literature. It is advisable to dissolve it in a saline solution or sterile water before use to ensure effective administration.

How is shipping temperature determined? And how is it related to the product storage temperature?
1 answer-
Products may be shipped at a different temperature than the recommended long-term storage temperature. If the product quality is sensitive to short-term exposure to conditions other than the recommended long-term storage, it will be shipped on wet or dry-ice. If the product quality is NOT affected by short-term exposure to conditions other than the recommended long-term storage, it will be shipped at ambient temperature. As shipping routes are configured for minimum transit times, shipping at ambient temperature helps control shipping costs for our customers. For more information, please refer to the Storage and Transport Conditions document: https://www.sigmaaldrich.com/deepweb/assets/sigmaaldrich/marketing/global/documents/316/622/storage-transport-conditions-mk.pdf

What is the best way to sterilize Heparin sodium salt?
1 answer-
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.
