A novel shark single-domain antibody targeting OGT as a tool for detection and intracellular localization [PDF]
IntroductionO-GlcNAcylation is a type of reversible post-translational modification on Ser/Thr residues of intracellular proteins in eukaryotic cells, which is generated by the sole O-GlcNAc transferase (OGT) and removed by O-GlcNAcase (OGA).

Shark IgNAR: The Next Broad Application Antibody in Clinical Diagnoses and Tumor Therapies? [PDF]
Antibodies represent a relatively mature detection means and serve as therapeutic drug carriers in the clinical diagnosis and treatment of cancer—among which monoclonal antibodies (mAbs) currently occupy a dominant position.

Isolation and characterization of malaria PfHRP2 specific VNAR antibody fragments from immunized shark phage display library [PDF]
Background Malaria rapid diagnostic tests (RDTs) represent an important antibody based immunoassay platform. Unfortunately, conventional monoclonal antibodies are subject to degradation shortening shelf lives of RDTs. The variable region of the receptor (

Therapeutic Potential of Shark Anti-ICOSL VNAR Domains is Exemplified in a Murine Model of Autoimmune Non-Infectious Uveitis [PDF]
Induced costimulatory ligand (ICOSL) plays an important role in the activation of T cells through its interaction with the inducible costimulator, ICOS. Suppression of full T cell activation can be achieved by blocking this interaction and has been shown

Expression Analysis of Heavy-Chain-Only Antibodies in Cloudy Catshark and Japanese Bullhead Shark [PDF]
Heavy chain-only antibodies in sharks are called immunoglobulin new antigen receptors (IgNAR), consisting of one variable region (VNAR) and five constant regions (C1-C5).

Humanization of the Shark V<sub>NAR</sub> Single Domain Antibody Using CDR Grafting. [PDF]
AbstractThe variable domain of the new antigen receptor (VNAR) of shark single domain antibodies is evolutionarily distant from the variable regions (VH) of mammalian immunoglobulins, yet it still has complementarity‐determining regions (CDRs) that are involved in antigen recognition, therefore making it possible to humanize by grafting these CDRs to ...

Improving the pharmacokinetic properties of biologics by fusion to an anti-HSA shark VNAR domain. [PDF]
Advances in recombinant antibody technology and protein engineering have provided the opportunity to reduce antibodies to their smallest binding domain components and have concomitantly driven the requirement for devising strategies to increase serum half-life to optimise drug exposure, thereby increasing therapeutic efficacy. In this study, we adopted

Shark‐derived vnarbodies 20G6 and 17F6 broadly neutralize SARS‐CoV‐2 Wuhan, Alpha, Beta, Kappa, Delta, Delta‐plus, Lambda variants, and sarbecovirus coronaviruses, but are unexpectedly ineffective for Omicron. Intranasal administration of 20G6 confers effective preventive and therapeutic effects in mice infected with SARS‐CoV‐2 Wuhan and Beta variant ...
