Application

Selenomethionine serves as a stable, bioavailable selenium analog of methionine, widely used in structural biology for X-ray crystallography via seleno-substitution. It incorporates a selenium atom in place of sulfur, enabling anomalous dispersion for phasing without disrupting protein folding. Its bench stability and compatibility with standard expression systems make it a practical choice for site-specific labeling in recombinant protein production.
