Predicted Molecular Weight
16.2kD
Accurate Molecular Mass
16kD as determined by SDS-PAGE under reducing conditions
Subcellular Location
Secreted, Extracellular Matrix
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 powder may be stored at -70°C. Stable for 6 months after receipt. Reconstitute with 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.
