Single B cell technology, also known as single B cell antibody preparation technology, is a novel method for rapid preparation of monoclonal antibodies. It relies on the analysis of Ig reactivity at the single cell level, utilizing cell sorting or sequencing techniques to acquire antibody-expressing genes. Through in vitro expression, a large number of specific monoclonal antibodies can be rapidly obtained in a short period of time. Each B cell only contains one functional heavy chain gene and one light chain gene sequence, thus producing only one specific antibody.
Compared with traditional hybridoma technology and phage display technology, the single B cell antibody technology boasts advantages such as a shorter development cycle, high throughput, numerous positive clones, and high affinity. Most importantly, antibodies obtained through this technique ensure the natural pairing of light and heavy chains.
Single B cell technology has been widely used in the preparation of highly specific human-derived antibodies against pathogenic microbial infections, such as HIV antibodies, tetanus antibodies, hepatitis B antibodies, influenza antibodies, and more. Additionally, it has demonstrated unique advantages and promising applications in fields like oncology, autoimmune diseases, and organ transplantation.
