Restrict Antibody Class

Use the dropdown to specify a chain class. The classification is hierarchical e.g. a search for Heavy Gamma chains will also retrieve chains classified as Heavy Gamma 2 A.

Public database sequences are classified in abYsis using a combination of sequence analysis results and where available, textual information provided by the data source.

Commercial Users: Proprietary sequences entered by the User through the Import function will be based purely on calculated results.

In some cases the textual information relating to chain type or class is missing or ambiguous, while in other cases sequence analysis fails to give a clear determination. Where there is inconsistency, the sequence analysis result is preferred and a warning is flagged. Some chains remain unclassified.

If you specify terms for both heavy and light chains in this section or elsewhere in the form, the search will be restricted to paired chains
