1OMP.pdb (MBP open — apo) uploaded. + 1ANF.pdb (MBP closed — holo) (holo). Select chains and fluorophore below.

Chains

Select which protein chains to analyse for labelling sites.

Single-molecule FRET

Scores residue pairs for optimal donor–acceptor placement.

Label Site Scoring

Ranks every residue as a potential labelling site for a single fluorophore.

FRET Dye Pair

The fluorescent dye you plan to attach. Each has different physical dimensions that affect which residues are accessible.

Compare Dye Pairs

Run a selection of common donor–acceptor FRET pairs and compare their top residue pairs side-by-side.

These are widely-used combinations, not an exhaustive set — the best pair depends on your Förster radius (R₀) and instrument. To score a different pair, just choose the donor and acceptor above and run a single analysis. Comparing all takes roughly 8× a single run; the individual dye selection is ignored when this box is checked.

Typically takes 10–60 seconds depending on protein size.
