Sequence Analyzer (CDR / Kabat)

Enter a heavy or light chain sequence (1-letter or 3-letter) to get CDR regions (CDR1, CDR2, CDR3) with Kabat numbering, plus molecular weight, pI, GRAVY, and charge at pH 7.4. Download a PDF report or copy CDR sequences for design and analysis. For 3D visualization of CDR loops use the CDR Highlighter; for export options see CDR Sequence Export and Export formats.

Research use only.
