A company that develops a vaccine for COVID19 has a strong need for the material QS-21.

 QS-21 is one of the most widely used and potent immunological, purified from the soap bark tree (Quillaja Saponaria). Bio-Lead managed to target a manufacturer with a capability to support long-term supply and a capacity of production that can support all stages of development of the vaccine, up to the commercial stage.

We have started the supply of QS-21 and the company will soon enter clinical trials using GMP grade QS-21. We managed to reduce the cost of this reagent by 50%.
