Store product at 4 degree C if to be used immediately within two weeks. For long-term storage, aliquot to avoid repeated freezing and thawing and store at -20 degree C. Aliquots are stable at -20 degree C for 12 months after receipt. Dilute required amount only prior to immediate use. Further dilutions can be made in assay buffer.

Recognizes human SPAK and OSR1 phosphorylated at Ser375 and Ser325 at ~60kD. Species Crossreactivity: mouse. Species Sequence Homology: rat and canine, 100%
