Hello everyone,

I am interested in obtaining some HBsAg containing the preS1 region. I would 
prefer if it was from a recombinant source.
Is there anyone that has information about it.
I would not mind to discuss my experiments  with someone that has this antigen.
If you know a company that sells such antigen it would be OK too.

Please write to ssechi at helix.nih.gov  if you have information.

Thanks for your interest.
