Discovery of Broadly Neutralizing Antibodies (bNAbs) has given a great boost to HIV vaccine research. Study of bNAbs capable of neutralizing a broad array of different HIV strains is important for a number of reasons: (i) structures of antigens co-crystallized with bNAbs are used as templates in HIV vaccine design; (ii) bNAbs can be effective as therapeutics; (iii) preventive use of bNAbs is a promising direction in AIDS care. The goal of bNAber is to collect, analyze, compare and present bNAbs data, thus helping researchers to create HIV vaccine.
Search for anti-HIV bNAbs that fit the following criteria. All criteria are combined to create the resulting dataset.

bNAber computes on the fly the percent viruses neutralized with an IC50 < 50 μg/ml and median IC50 (μg/ml) against viruses neutralized with an IC50 < 50 μg/ml. The value that were computed on the fly are indicated with asterisk (*) on bNAb Details Page. Clicking on these values brings you original neutralization data from publication.
Blast search is available
A new service has been added to bNAber: now you can do blast search to find sequence similarity with bNAbs in the database (H- and L-chains, both nucleotide or amino acids). Just click on the BLAST tab. New interface will give a compact presentation of blast results.

bNAbs to Flu
Recently, discovery of broadly neutralizing antibodies to influenza virus has identified two major supersites of vulnerability on the influenza virus hemagglutinin, one involved in receptor binding and the other, in fusion machinery.
