Abnova offers Camelid Single Domain Antibody Service for production of target-specific SdAb from naive camelid VHH library. By using the advanced naive camelid VHH library screening technology, we screen the library and isolate the SdAb clones for your required antigens. Positive clones are sequenced and validated by ELISA. The selected clones will then be introduced into HEK293 expression vector or E. coli expression vector for transient and scalable SdAb production for many downstream applications.
