General description

Heparin ist ein Glykosaminoglykan (GAG), das zur Familie der Mucopolysaccharide gehört und für seine starken gerinnungshemmenden Eigenschaften bekannt ist. Dieses stark sulfatierte Polysaccharid besteht aus D-Glucosamin und Hexuronsäure, die über glykosidische Bindungen miteinander verbunden sind. Es findet breite Anwendung in der biochemischen Forschung und in Zellkulturstudien.

Application

Heparinnatriumsalz aus der Darmschleimhaut von Schweinen wurde in dem Medium zur Befruchtung von Oozyten mit Spermien ergänzt. Heparin-Natriumsalz aus der Darmschleimhaut vom Schwein wird verwendet:
  • zur Prüfung der Wirkung von Heparin auf den Fibroblasten-Wachstumsfaktor 21 (FGF21)-Signalweg
  • bei der Immunfärbung von Gehirnschnitten von Mäusen
  • zur Quantifizierung von weißen und roten Blutkörperchen in Sparus-aurata-Blutproben
  • bei Antikoagulationstests und beim Inhibitionstest für SARS-CoV2 (schweres akutes respiratorisches Syndrom Coronavirus 2 )

Biochem/physiol Actions

Heparin ist vorwiegend für die Verzögerung der Blutgerinnung verantwortlich. Es verstärkt die Antithrombin-vermittelte Inaktivierung von Proteasen im Gerinnungsweg.

Heparin wird in Mastzellen und Mediatoren wie Histamin synthetisiert und wird mit Allergien und Entzündungsvorgängen in Verbindung gebracht Heparin wird zur Therapie von Venenthrombose und Lungenembolie, zur Prävention eines Thromboserezidivs nach einer Thrombolyse und zum Management arterieller Thrombosen bei Patienten mit akutem Herzinfarkt eingesetzt. Heparin übt eine entzündungshemmende Wirkung bei zahlreichen entzündlichen Erkrankungen wie Verbrennungen, Asthma bronchiale und Colitis ulcerosa aus.

Questions

1–10 of 11 Questions  
  1. What does Grade I-A mean?

    1 answer
    1. "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.

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

    1 answer
    1. 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.pdf

  3. 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
    1. 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.

  4. How is shipping temperature determined? And how is it related to the product storage temperature?

    1 answer
    1. 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

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

    1 answer
    1. 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).

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

    1 answer
    1. 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.
