Example 4
The Molecular Operating Environment (MOE) software developed by Chemical Computing Group (CCG) are used to generate alignments between the rabbit antibody clone 132, clone 154 and clone 163 and pairs of variable light and heavy chains, VL and VH, respectively from two databases:
-
- (1) The Abysis human database: a database of about 2000 known human VL/VH sequence pairs from IMGT-LigM DB; and
- (2) A human germline database: a database of germline sequences.
Humanized models show the best sequence alignments (highest identity to both the VL and VH domains) with fewest gaps. The top 100 antibody pairs from each human database are exported and clustered using kClust (Hauser, Mayer, & Soding, (2013) BMC Bioinformatics, 248).
