Fumonisin B1 is a mycotoxin produced from F. moniliforme, a prevalent fungus of corn and other grains. Outbreaks of food poisoning in livestock and humans following the consumption of Fusarium infested corn are caused by fumonisins.1 It functions as an inhibitor of ceramide synthase (sphingosine N-acyltransferase).2 Fumonisin B1 attenuates the response of P388D1 cells to PAF and LPS by inhibiting ceramide formation.3 It also blocks the apoptotic response of HaCaT cells to the antiproliferative drug hexadecylphosphocholine, again through inhibition of ceramide production.4 Incubation of Swiss 3T3 cells with fumonisin B1 results in both an altered cell morphology due to disruption of axonal growth and a decrease in cell proliferation.5

Cayman Chemical Company regularly evaluates our shipping methods to ensure product stability is maintained and our corporate environmental impact is minimized. Products selected for review are evaluated and shipping methods are certified by our Scientists. While occasionally our method of shipping a product may change, rest assured the shipping conditions on all Cayman Chemical products have been reviewed and validated.
Upon receipt, it is important to check the storage requirements of your products and place them at the appropriate temperature. Products shipped without ice may require frozen storage for long term stability.
Cayman Chemical was formed over thirty years ago by demonstrating the value of naturally growing gorgonian corals as a renewable, economically viable source of prostaglandins. Today we operate our business knowing that we owe our start to the renewable resources our environment had provided. As Cayman Chemical continues to grow we consistently evaluate our business processes to ensure we are operating at the highest environmental standards.
