For Fluorophore (AMCA, Cy2, FITC, Cy3, TRITC, RRX, TR, Cy5) Conjugates, Biotin-SP Conjugates, and Horseradish Peroxidase Conjugates:     top of page

Physical State : Freeze-dried powder

 Reconstitution and Storage : Store freeze-dried powder at 2-8°C. When ready to use, rehydrate with indicated volume of d. water and centrifuge if not clear. Product is stable for about 6 weeks at 2-8°C as an undiluted liquid. Prepare working dilution fresh each day. For extended storage after rehydration, add an equal volume of glycerol ( ACS grade or better) for a final concentration of 50%, and store at -20°C as a liquid. Note: after the addition of glycerol, the concentration of protein and buffer salts is one-half of the original. Alternatively, aliquot and freeze the product at -70°C or below in the absence of glycerol. Avoid repeated freezing and thawing. Expiration date: one year from date of rehydration.
