am doing the thesis under the topic "Production and Characterization of 
Monoclonal Antibodies against Hepatitis B surface antigen". After getting 
desirable clones, I have a big problem. For characterization,I do not 
have subtype panel of Hepatitis B surface antigen ; only subtype adr and 
adw that I have.I would like to have other subtypes ; ayr , ayw.

subtypes above or available in hand. Please inform me. I  am very truly 
need your help.
     Thanks in advance.
     Tammy.
