DBCO- and Biotin-conjugated sdAbs (1:1 labeling on the C-terminus) are lyophilized from PBS pH 7.4. Unconjugated sdAbs are lyophilized from 5 mM KPi pH 6.0, 300 mM NaCl, 0.5 mM EDTA pH 6.0. Reconstitute with 250 µL pure deionized water for immediate use or with 250 µL sterile 50% glycerol for storage at -80°C. For more details, click the Protocols button above and check Reconstitution and Storage.

Vials containing lyophilized reagent can be stored at 2-8°C for up to 12 months. After reconstitution, store at -80°C for up to 6 months. Working aliquots can be stored at -20°C for up to 4 weeks. For more details, click the Protocols button above and check Reconstitution and Storage.
