Packaging

1 g in poly bottle

500 mg in poly bottle

Preparation Note

Prepared by a modification of the method of Black, W.A.P., et al., J. Sci. Food Agri., 3, 122 (1952).

Application

Fucoidan from Fucus vesiculosus may be used as a biological response modifier and as a potential therapeutic agent with a wide range of biological activities. It may be used to study its pharmacokinetics, safety, efficacy and methods of delivery as a potential anticancer, anti-immune and anti-inflammatory agent. Fucoidan may be used to assess its potential and formulations for tissue engineering applications.

Biochem/physiol Actions

Studies of fucoidan have found it to have a broad variety of biological activities including antitumor and antiangogenic activities, immunomodulatory, anti-inflammatory, anticoagulant, antithrombotic, and antioxidant activities. Fucoidan induces macrophage activation with subsequently activates mitogen activated protein kinases (MAPKs) and results in natural killer cell proliferation. Fucoidan acts as a nonselective selectin blocker and has been shown to induce apoptosis and suppress angiogenesis.

Frequently Asked Questions

How does the storage temperature relate to shipping conditions?
The storage conditions that a Sigma-Aldrich catalog and label recommend for products are deliberately conservative. For many products, long-term storage at low temperatures will increase the time during which they are expected to remain in specification and therefore are labeled accordingly. Where short-term storage, shipping time frame, or exposure to conditions other than those recommended for long-term storage will not affect product quality, Sigma-Aldrich will ship at ambient temperature. The products sensitive to short-term exposure to conditions other than their recommended long-term storage are shipped on wet or dry ice. Ambient temperature shipping helps to control shipping costs for our customers. At any time, our customers can request wet- or dry-ice shipment, but the special handling is at customer expense if our product history indicates that the product is stable for regular shipment. http://www.sigmaaldrich.com/etc/medialib/docs/Sigma-Aldrich/General_Information/shippingandlong-termstoragev3.Par.0001.File.tmp/shippingandlong-termstoragev3.pdf
