cyclosporin A

[Nora Plesofsky-Vig]

I am interested in obtaining cyclosporin A and, if possible,  
ornithine-derivatized cyclosporin A (to make an affinity column).  
Their purpose is to isolate cyclophilins and associated proteins from  
cells. I am not aware of commercial sources of cyclosporin A or its  
derivative. If you know where these are available for purchase, or if  
you would be willing to provide small amounts of these, I would be  
very grateful.
