VNAR development through antigen immunization of Japanese topeshark (Hemitriakis japanica) [PDF]
Frontiers in Bioengineering and Biotechnology, 2023 The VNAR (Variable New Antigen Receptor) is the smallest single-domain antibody derived from the variable domain of IgNAR of cartilaginous fishes. Despite its biomedical and diagnostic potential, research on VNAR has been limited due to the difficulties ...

Bamboo Shark as a Small Animal Model for Single Domain Antibody Production [PDF]
Frontiers in Bioengineering and Biotechnology, 2021 The development of shark single domain antibodies (sdAbs) is hindered by the high cost and tediousness of large-sized shark farming. Here, we demonstrated white-spotted bamboo sharks (Chiloscyllium plagiosum) being cultivated commercially as a promising ...

Generation of shark single-domain antibodies as an aid for Cryo-EM structure determination of membrane proteins: Use hyaluronan synthase as an example [PDF]
Journal of Structural Biology: XIn cartilaginous fish, the immunoglobulin new antigen receptor (IgNAR) is naturally devoid of light chains. The variable regions of IgNAR (VNARs) are solely responsible for antigen recognition, similar to VHHs (variable domain of the heavy chain of heavy-
