am doing my thesis under the topic"Production and Characterization of 
Monoclonal Antidodies against Hepatitis B surface antigen. After getting 
desirable clones,I have a big problem.For characterization of those 
MAbs,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

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