Lyophilized powder may be stored at 4 degree C. Reconstitute to nominal volume by adding sterile ddH2O. Aliquot and store at 4 degree C. Reconstituted product is stable for 6 months as an undiluted liquid. Dilute only prior to immediate use. Freezing R-Phycoerythrin (PE) conjugates will result in a substantial loss of activity. PE conjugates are sensitive to light. For maximum recovery of product, centrifuge the original vial prior to removing the cap. Further dilutions can be made in assay buffer.
