VHH and the blood–brain barrier challenge

VHH and the blood–brain barrier challenge

The blood–brain barrier remains a critical bottleneck in CNS drug delivery, excluding nearly all biologics. VHH antibodies offer a practical route forward, combining small size, stability, and engineering flexibility to enable receptor-mediated transport into the brain. This article examines transport mechanisms, emerging applications, and how synthetic VHH libraries support the development of brain-penetrant biologics. Read more

How VHHs Can Redefine the Next Generation of ADCs

How VHHs Can Redefine the Next Generation of ADCs

Antibody–drug conjugates (ADCs) remain one of the most promising modalities in oncology, but the next generation demands smarter, more adaptable scaffolds. Single-domain antibodies bring precisely that: offering high affinity and stability in a compact, engineerable scaffold. By merging these two platforms, we get an antibody framework that can address long-standing bottlenecks in the industry. Read more

Building Smarter Therapeutics with VHH Bolt-Ons

Building Smarter Therapeutics with VHH Bolt-Ons

VHH antibodies provide modular, high-performance components that can enhance biologics across multiple modalities. From albumin-binding half-life extension to bi-/multi-specific engineering and intracellular TPD, VHH bolt-ons enable more flexible, efficient and targeted therapeutic design. This article examines the key applications, design considerations e case studies that illustrate how VHH domains support next-generation engineered biologics. Read more

Explore the science behind our antibody discovery platforms

Access our latest white papers and application notes to see how Isogenica’s synthetic VHH technologies are accelerating innovation in CAR-T, bispecifics, and immuno-oncology.
White Paper “Data-Driven Validation of Synthetic VHHs”
This white paper provides a data-driven validation of Isogenica’s synthetic VHH libraries, powered by Colibra® technology. Designed for biotech and pharmaceutical scientists, it demonstrates how these libraries enhance and accelerate drug discovery, particularly in oncology and immunotherapy.   Download
Extending half-lives of VHH antibodies
Because VHHs are small, they can be cleared quickly from the bloodstream. This can be a useful feature for some applications, but often a longer plasma half-life is desirable. DOWNLOAD
Advantages of VHH in bi-specifics
To learn more about the application of VHHs in bi-specifics, we have condensed our expertise into a downloadable Application Note. DOWNLOAD
Optimizing CAR-T and T-cell antibody engagers: a role for VHH single domain antibodies
This whitepaper summarises the clinical and research landscape for CAR-T and T-cell engaging antibody therapies and show how single domain VHH antibodies can be applied to optimise the next generation of these important new therapeutic modalities. DOWNLOAD
Isogenica’s PD-L1 VHH as Functional Antagonists
PD-1 is an immune checkpoint protein expressed on the surface of multiple types of immune cells, including antigen-stimulated T-cells and tumour specific T-cells1. Interaction between PD-1 and its ligands (PD-L1 or PD-L2), is responsible for the regulation of T-cell activation, apoptosis, proliferation and cytokine production. DOWNLOAD
Anti-LRP5/6 VHH inhibits WNT pathway and prevents tumour growth
VHH are the variable domain of heavy chain only antibodies. They are small in size (~15 kD) and biophysically robust. With tunable half-lives, these antibodies are ideal for targeting inaccessible epitopes, achieving enhanced tissue penetration, multi-target binding and formatting for payload delivery… DOWNLOAD
