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.

Description générale
Application
- pour vérifier l'effet de l'héparine sur la signalisation par FGF21 (facteur de croissance de fibroblastes 21)[5][5].
- dans l'immunomarquage de coupes de cerveau de souris[6].
- pour quantifier les globules blancs et les globules rouges dans des échantillons de sang de Sparus aurata[7].
- dans un essai sur l'anticoagulation et l'inhibition du coronavirus 2 responsable du syndrome respiratoire aigu sévère (SARS-CoV2).[8]
Actions biochimiques/physiologiques
L'héparine est synthétisée dans les mastocytes au même titre que certains médiateurs comme l'histamine ; elle est associée aux allergies et présente une activité anti-inflammatoire.[10] L'héparine possède des effets thérapeutiques contre la thrombose veineuse et l'embolie pulmonaire, aide à prévenir la thrombose récidivante post-thrombolyse et traite la thrombose artérielle chez les patients souffrant d'infarctus aigu du myocarde. L'héparine possède une action anti-inflammatoire dans de nombreuses pathologies inflammatoires telles que les brûlures, l'asthme bronchique ou la colite ulcéreuse.[2]

How can I determine the shelf life / expiration / retest date of this product?
1 réponse-
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.

How is shipping temperature determined? And how is it related to the product storage temperature?
1 réponse-
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 réponse-
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.
