The ABCD (for AntiBodies Chemically Defined) database is a repository of sequenced antibodies, integrating curated information about the antibody and its antigen with cross-links to standardized databases of chemical and protein entities. It is freely available to the academic community, accessible through the ExPASy server (https://web.expasy.org/abcd/). The ABCD database aims at helping to improve reproducibility in academic research by providing a unique, unambiguous identifier associated to each antibody sequence. It also allows to determine rapidly if a sequenced antibody is available for a given antigen.

ABCD数据库：化学定义的抗体的存储库。

ABCD（用于化学定义的抗体）数据库是已测序抗体的存储库，将有关抗体及其抗原的精选信息与交联的化学和蛋白质实体标准化数据库整合在一起。它可通过ExPASy服务器（https://web.expasy.org/abcd/）访问，可供学术界免费使用。ABCD数据库旨在通过提供与每个抗体序列相关的唯一，明确的标识符来帮助提高学术研究的可重复性。它还允许快速确定测序抗体是否可用于给定抗原。
