Visual ADC3D Viewer
View structures in-site—no redirect. Enter a PDB ID or pick a structure below (antibody–payload complex). Rotate (drag), zoom (scroll), measure, export PNG/PDB, copy cite — all in the viewer bar and sidebar. Payload Distribution
For ADCs: load an antibody–payload complex PDB to view and export. Use Antibody-Payload Complex to upload your own file; use Payload Distribution to preview payload distribution or multi-frame structures. Export PDB or PNG from the viewer. For DAR and mass see DAR Calculator and Linker Library; for report export see Report Export and Export formats.
Crambin, small protein; useful for small-molecule and crystallography reference.

How to use the 3D viewer
- Rotate & zoom: Drag to rotate the structure; scroll to zoom in/out.
- Chains: Use the checkboxes in the viewer bar to show or hide each chain.
- Display mode: Switch between cartoon, stick, line, or sphere in the viewer bar.
- Seq ↔ 3D: In the right sidebar, open the panel to see residue numbers by chain; click a number to center the view. Hover in 3D to highlight the same residue in the panel.
- Hover: Move the mouse over the structure to see residue info in the bottom-left overlay; the hovered residue is highlighted in red.
- Measure: Turn on Measure in the bar, then click two atoms to see the distance (Å) and a red line.
- Share: Use Copy link above to copy this structure’s URL. Export PNG, Download PDB, and Copy Cite are in the right-hand sidebar.
