Learn moreOur exclusive shark platform
Decades have passed since the discovery of the peculiar heavy-chain antibodies in camelids (VHH), followed by the elucidation of the similar, heavy-chain-only structure of sharks' new antigen receptors (vNAR). Both of them share several characteristics such as high stability and solubility, longer than average CDR3 loops, and the presence of non-canonical disulfide linkages sculpting the binding site.
While VHH domains have attracted great interest as biological drugs and proven to be successful in clinical trials, the engineering of vNAR domains for biomedical applications is at an early stage. Despite this, it is abundantly clear that they present a singular molecular framework that can be exploited to develop reagents for scientific research, disease diagnosis, and/or therapeutic intervention.


Discovery services
Jotbody provides discovery services for nanobodies from immunized and naive libraries. We source the best alpaca livestock in Australia for our immunization program, generating diverse immune responses and high-quality antibodies. Our experienced scientists work closely with clients to deliver tailored solutions and successful outcomes.
Why nanobodies?
Nanobody, also called single-domain antibody, is the variable region isolated from the antigen-binding variable domain (VHH) of camelid heavy chain-only antibody or the variable domain (vNAR) of cartilaginous fish immunoglobulin new antigen receptor (IgNAR). With a size of just 12~15 kDa (2~4 nm), nanobody is the smallest antigen-binding fragment discovered today and holds a plethora of intrinsic advantages over conventional monoclonal antibodies.

Immunized vs naïve libraries
Antibody libraries can be generated from immune hosts who have developed a strong and specific humoral response against the desired target or naïve hosts who have never been challenged with a specific immunogen. Whether you need a partner to develop high-diversity immune libraries for antibody phage display or ready-made naïve antibody libraries, Jotbody offers them all to suit your needs.
