BOSTON<\/span><\/span>, June 1, 2024<\/span><\/span> \/PRNewswire\/ — Immunocan announces significant progress in the construction of its alpaca-derived nanobody discovery platform, ImmuAlpaca\u00ae mouse. The IGH-VDJ genes in the mouse genome have been successfully replaced\u00a0by alpaca IGH-VDJ genes in-situ.<\/p>\n

In 1993, naturally occurring heavy-chain-only antibodies (HCAbs) were discovered. Compared to the heavy chain variable regions of traditional antibodies, the variable domain of heavy\u00a0chain\u00a0of HCAbs (VHH) from camelids (also known as nanobodies)\u00a0have four aliphatic amino acid residues in the FR2 region replaced by hydrophilic amino acids. \u00a0This substitution confers greater stability in the absence of a light chain. Nanobodies are the smallest antigen-binding fragments found in nature.\u00a0With a molecular weight of only 15 kDa, nanobodies offer great flexibility and are easy to\u00a0use as components for constructing therapeutic molecules in innovative format such as multivalent and multispecific antibody molecular structures.\u00a0Over the past 20 years, extensive research and development achievements have\u00a0demonstrated the significant value of nanobodies in clinical therapeutic use.<\/p>\n

Currently, nanobodies can be obtained mainly through three approaches: camelid immune libraries, na\u00efve camelid libraries, and fully synthetic libraries. Among these, camelid immune libraries are the most widely used for screening. However, due to the large size and low reproductive rate of camelids, the required antigen amount for immunization is high and the immunization strategy employed in one discovery campaign is limited. Besides, lacking standardized breeding and experimental facilities further impacted their reliability and performance. A novel approach is needed to keep up with the increasing demand for nanobody-based drug discovery.<\/p>\n

Immunocan has developed the innovative camelid-derived nanobody discovery platform, ImmuAlpaca\u00ae mouse, through patented MASIRT\u00ae technology. This platform\u00a0enables nanobody discovery using robust strategy and methods from standard mice model. MASIRT\u00ae technology involves replacing the IGH-VDJ\u00a0(Variable, Diversity and Joining segments of immunoglobulin heavy locus)\u00a0genes in the mouse genome with camelid-derived IGH-VDJ genes in-situ. Immunization of ImmuAlpaca\u00ae mouse can generate highly diversified nanobody libraries. This allows for the use of diversified immunization and antibody screening strategies common in mouse models, significantly improving the performance of nanobody molecule discovery.<\/p>\n

In addition to the ImmuAlpaca\u00ae mouse, Immunocan has already developed the ImmuMab Heavy\u00ae mouse, generating fully human heavy-chain-only antibodies and is constructing the ImmuHeavy\u00ae rabbit, generating rabbit heavy-chain-only antibodies.\u00a0Using these models will expand the sequence space for nanobody discovery at multiple level. By leveraging the advantages of antibody sequences and structures from different species, exploring more target epitopes and therapeutic mechanisms will be easier.<\/p>\n
