biosyn selenium: selenase®

With its blockbuster selenase®, biosyn is the global market leader in both high-dose selenium injectable pharmaceuticals and selenium formulations for treating sepsis. biosyn supplies selenase® to 22 countries worldwide.

The active ingredient in selenase® is sodium selenite pentahydrate, which is converted by the body into metabolizable selenium via selenoproteins. Selenium, a trace mineral with antioxidant and anti-inflammatory effects, is essential for glutathione, iodine and thyroid metabolism.


Selenium deficiency may increase the risk of mortality, poor immune function and cognitive decline. Selenium supplementation may confer antiviral effects and reduce risks for many diseases like autoimmune thyroiditis, prostate, lung, colorectal and bladder cancers, among others.

Throughout the world, selenase® is administered daily in critical care settings. Its benefits for patients:

  • reduced mortality
  • protection from endothelial and organ damage
  • modulation of inflammatory and coagulation pathways
  • very well tolerated

biosyn hemocyanin: IMMUCOTHEL® and VACMUNE®

biosyn is world leader in the GMP-compliant manufacturing of high-quality, clinical- and research grade hemocyanin products derived from the hemolymph of the sea snail, Meghathura crenulata, also commonly known as the Giant Keyhole Limpet.

Giant Keyhold Limpet (Meghathura crenulata)
Giant Keyhold Limpet (Meghathura crenulata)

The hemocyanin derived from this snail is called Keyhole Limpet Hemocyanin (KLH). The subunits of hemocyanin are defined as immunocyanin. The amount of immunocyanin (IMMUCOTHEL®) obtained from one keyhole limpet is roughly sufficient to treat one bladder cancer patient for a year. At present, this pharmaceutical is only approved for use in a few countries, where it is leading to successful outcomes.

VACMUNE®, produced from immunocyanin, serves as carrier for advanced vaccines. That is why major drugmakers use VACMUNE® in pivotal research projects currently focused on brain tumors, common forms of cancer, hypertension and Alzheimer’s.
