Lyophilized powder may be stored at -20 °C. Stable for 12 months at -20 °C. Reconstitute with sterile ddH2O. Aliquot to avoid repeated freezing and thawing. Store at -20 °C. Reconstituted product is stable for 12 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. Labeled with horseradish peroxidase (HRP). Sodium azide is a potent inhibitor of peroxidase and should not be added to HRP conjugates. HRP conjugates are sensitive to light.

Recognizes human IgM. Assay by immunoelectrophoresis resulted in a single precipitin arc against anti-peroxidase, anti-goat serum, human IgM and human serum. No reaction was observed against anti-pepsin, anti-goat IgG F(c), human IgG or human IgA. Does not crossreact with other human heavy or light chain isotypes.
