"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.

Descrizione generale
Applicazioni
- per verificare l'effetto dell'eparina sulla trasduzione del segnale dell'FGF21 (fattore di crescita dei fibroblasti 21);[5][5]
- per l'immunocolorazione di sezioni cerebrali murine;[6]
- per quantificare leucociti ed eritrociti in campioni di sangue di Sparus aurata;[7]
- nel dosaggio dell'anticoagulazione e nei saggi di inibizione del coronavirus 2 responsabile della sindrome respiratoria acuta grave (SARS-CoV-2)[8]
Azioni biochim/fisiol
L'eparina viene sintetizzata dai mastociti, i quali la rilasciano insieme ad altri mediatori, come l'istamina, che intervengono nelle reazioni allergiche e infiammatorie.[10] Il suo effetto terapeutico si esplica nel contrasto alla trombosi venosa e all'embolia polmonare, nella prevenzione dello sviluppo di nuove trombosi post-trombolisi e nella gestione delle trombosi arteriose in pazienti con infarto acuto del miocardio. L'attività antinfiammatoria dell'eparina interviene in molte condizioni infiammatorie come le ustioni, l'asma bronchiale e la colite ulcerosa.[2]

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

please, could you explain me if this Heparin H3393 in one 'high molecolar wieght heparin'?
1 risposta-
This product is a porcine heparin with a molecular weight range of 15-19 kDa. This material is considered a "high molecular weight heparin." According to the literature, low molecular weight heparins are those with a molecular weight of less than 8000 Da. See the link below to review a publication that may be helpful:

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