Sample preparation

This product was purified by size exclusion chromatography and lyophilized in 10mM potassium phosphate buffer pH 6.5.
To prepare a working 0.5 mg/mL solution, resuspend the lyophilized Streptavidin poly-HRP in 1000 µL of 0.5× PBS pH 7.4 or in commercially available HRP stabilizer.
For long term storage, add 0.01% thiomersal or any other suitable preservative to the solution. Do not add sodium azide.
Store prepared solution at 4˚C. For long-term storage, aliquot and store at -20˚C.
