Cholecystokinin 4, Tetrapeptide (CCK4), Recombinant, Human, His-Tag, SUMO-Tag

Source:
Recombinant protein corresponding to Ala31~Phe333 from human Cholecystokinin 4, Tetrapeptide, fused to His-Tag & SUMO-Tag at N-terminal, expressed in E. coli.

Molecular Weight:
~47.3kD

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 -20°C. Reconstitute with sterile buffer. Aliquot to avoid repeated freezing and thawing. Store 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.

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.
