Streptavidin Maleimide Conjugate is designed to facilitate the conjugation of the Streptavidin to proteins, peptides and ligands that contain a free sulfhydryl (-SH) groups.

1. Allow the vial of Streptavidin Maleimide Conjugate to warm to room temperature.
2. Reconstitute the Streptavidin Maleimide Conjugate by adding a buffered solution of the thiol-containing molecule. Gently agitate the vial to ensure thorough dissolution.
Note: The buffer in which the thiol-containing molecule is dissolved should be in the pH range 6.5-7.5. Phosphate buffered saline pH 7.2 is commonly employed. Maleimides react with sulfhydryls at pH 6.5-7.5 to form stable thioether bonds. EDTA (1-10 mM) may help to prevent metal catalysed oxidation of thiols.
3. React for 30–60 minutes at 37 °C or 2 hours at room temperature.
4. If desired, desalt, dialyze or purify the conjugate.

Store at -20 °C to -80 ºC (Preferably at -80 ºC). Reconstitute this reagent immediately before use. Do not prepare stock solutions for storage. Discard any unused reconstituted reagent.
