Predicted Molecular Weight:
23.7kD

Accurate Molecular Mass:
25kD as determined by SDS-PAGE reducing conditions

Subcellular Location:
Secreted

Applications:
Suitable for use in ELISA, Western Blot and SDS-PAGE. Other applications not tested.

Recommended Dilutions:
Optimal dilutions to be determined by the researcher.

Storage and Stability:
Lyophilized and reconstituted products are stable for 6 months after receipt at -70°C. Reconstitute with sterile sterile 20mM Tris, 150mM sodium chloride, pH 8.0. Aliquot to avoid repeated freezing and thawing. Store at -70°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.

Note:
Thermal stability is described by the loss rate of the target protein. The loss rate was determined by accelerated thermal degradation by incubating the protein at 37°C for 48h, with no obvious degradation or precipitation observed. Protein loss is <5% within the expiration date under appropriate storage conditions.
