Generation of VNAR Libraries from Immunized Sharks
Generation of VNAR Libraries from Immunized Sharks and Selection of Target-Specific Clones Helen Dooley ABSTRACT: Cartilaginous fishes (sharks, skates, rays, and chimeras) are the most phylogenetically distant lineage relative to mammals in which somatically rearranging immunoglobulins (Igs or antibodies) have also been found. Alongside their conventional (heavy-light chain) isotypes, IgM and IgW, sharks produce the novel

Towards a new understanding of elasmobranch hearing
Towards a new understanding of elasmobranch hearing Megan F. Mickle, Dennis M. Higgs ABSTRACT: Elasmobranchs are of important global conservation concern, however their hearing abilities, use of sound, and responses to anthropogenic noise pollution are all vastly understudied, despite noise pollution being an ever-increasing concern to global fish populations. This review focuses on the hearing
