The core data of the BDB database are sets of biopanning data and related information such as sequences, structures, targets, templates and libraries. Peptides are grouped into a set of biopanning data if they are from the same independent experiment. In the current release, 29,333 peptides grouped into 3,264 sets are collected from 1,521 published papers. Among the 29,333 peptides in BDB, 25,043 peptides appear only in one set of biopanning data; however, there are 1,669 peptides appearing in two or more sets of biopanning data for 4,290 times in total.

Target:

There are 1953 different targets in the current version of BDB. Besides 184 target with undetermined sources and 162 targets with no sources (such as cellulose, polystyrene, microplate, etc.), most of the targets are from Homo sapiens (Human) and Mus musculus (Mouse). The source of some targets are a hybrid of two or more species.

Template:

For most of the peptides in the BDB database, their templates are not or even can not be determined. Thus, there are only 542 templates identified.

Library:

In the current version of the BDB database, there are 470 phage libraries or library pools.
