May be stored at 4 °C for short-term only. For long-term storage and to avoid repeated freezing and thawing, add sterile glycerol (40-50%), aliquot and store at -20 °C. Aliquots are stable for at least 6 months at -20 °C. For maximum recovery of product, centrifuge the original vial after thawing and prior to removing the cap. Further dilutions can be made in assay buffer.<br>

IEP assay shows a single precipitin arc against anti-canine serum and anti-canine IgM (mu chain specific). No reaction against anti-canine IgGFc. Some light chain cross reactivity will occur with anti-canine IgG.
