Automatic isotype annotation was performed by aligning the constant heavy domain 1 (CH1) of any given Ab sequence against the IMGT isotype reference ( 37) of the respective species using the Smith–Waterman ( 38) algorithm. The H chain sequences were automatically annotated with isotype information unless such data were given in the corresponding publication. In this study, we identify, clean, annotate, and make the data available as a starting point for immunodiagnostics analyses.

Ultimately, because immunoinformatics is not the chief focus of such services, bulk data download from such websites is limited, and converting the raw nucleotide data obtained into a format suitable for analysis still requires installation and running additional software packages. These services chiefly focus on facilitating bulk deposition of raw data to perform standardized sequencing analyses. The iReceptor and the VDJServer are the main resources that fall under the umbrella of the organized effort of the Adaptive Immune Receptor Repertoire Community to provide standardized deposition and analysis pipelines for the Ig-seq outputs ( 24). Some of these issues are addressed by services that provide Ig-seq–specific data deposition and analysis pipelines such as the B-T.CR wiki ( ), ImmPort ( ) ( 26, 27), immunoSEQ Analyzer ( ), iReceptor ( ) ( 28), or VDJServer ( ) ( 29). It requires nontrivial ad hoc effort to convert such raw reads to amino acid sequences that ultimately dictate the molecular structure and Ag recognition. Furthermore, the data are typically deposited as raw nucleotide reads. Metadata, such as isotype, age, or subject identifiers, are not typically standardized therefore, extraction of specific subsets of Ab repertoires for comparative analyses is challenging. This has meant that the outputs of Ig-seq studies are fragmented across repositories, making it difficult to perform large-scale data mining of Ab repertoires ( 25). Technical advances in sequencing technology have outpaced storage and analysis pipelines ( 24, 25). We believe OAS will facilitate data mining of immune repertoires for improved understanding of the immune system and development of better biotherapeutics. The data within OAS will be regularly updated with newly released Ig-seq datasets. We have sorted, cleaned, annotated, translated, and numbered these sequences and make the data available via our Observed Antibody Space (OAS) resource at. To address this issue, we have collected Ig-seq outputs from 55 studies, covering more than half a billion Ab sequences across diverse immune states, organisms (primarily human and mouse), and individuals.

However, Ig-seq outputs are currently fragmented across repositories and tend to be presented as raw nucleotide reads, which means nontrivial effort is required to reuse the data for analysis. Recently, it has become possible to query their immense natural diversity using next-generation sequencing of Ig gene repertoires (Ig-seq). Their sequence diversity and binding versatility have made Abs the primary class of biopharmaceuticals. Abs are immune system proteins that recognize noxious molecules for elimination.
