Hi there, Is there any way to detect just the Fab region of an antibody using a protein fasta file and Biopython? I was originally considering just using regex for finding conserved regions of the hinge and cutting there but was wondering if there was a feature in Biopython that can do this already? Or is there a less heavy handed way to achieve this? We are mainly looking at IgGs and interested in only the Fab region for analysis. Thanks!
