Variable domain of Heavy chain of Heavy-chain-only antibody
Full Form of VHH
What is VHH?
VHH refers to the variable domain of heavy-chain-only antibodies, which are naturally found in camelid animals such as camels, llamas, and alpacas. These small antibody fragments, commonly called nanobodies, have gained significant attention in biotechnology and pharmaceutical research due to their tiny size, remarkable stability, and ability to bind unique molecular targets that conventional antibodies cannot easily access. In India, leading research institutions including the Indian Institute of Science Bangalore, the National Institute of Immunology New Delhi, and several biotechnology startups are actively working on VHH-based therapeutics targeting cancer, viral infections, and autoimmune disorders. The COVID-19 pandemic greatly accelerated VHH research across the country, with Indian biotech firms developing nanobody-based diagnostic kits and therapeutic candidates. These versatile molecules are also used in advanced medical imaging, targeted drug delivery, and agricultural biotechnology applications. For students preparing for competitive exams such as CSIR-NET Life Sciences, DBT-JRF, GATE Biotechnology, ICMR examinations, or AIIMS and JNU entrance tests, understanding VHH and its applications has become essential as it represents a rapidly expanding frontier in modern immunology and molecular biology research.
