Thank you for your enquiry. I can confirm that ab20930 Anti-Hepatitis B Virus Surface Antigen (Ad/Ay) antibody is a goat polyclonal antibody. Is is very unusual to have isotype controls for polyclonal antibodies, becuase they contain a mixture of isotypes. Therefore, regrettably we do not have a goat polyclonal isotype control available in the catalogue. I am sorry there are no suitable isotype controls to meet your requirements on this occasion. Should you have any further questions, please do not hesitate to contact us.
