		Technical Data
C5042-09	CCK4 (Colon Carcinoma Kinase 4, CCK-4, Inactive Tyrosine-protein Kinase 7, Protein-tyrosine Kinase 7, PTK7, Pseudo Tyrosine Kinase Receptor 7, Tyrosine-protein Kinase-like 7)

Description:
CCK4 (colon carcinoma kinase 4, also known as PTK7) is a receptor tyrosine kinase (RTK) involved in colon carcinoma development and/or proliferation. Similar to the RTK HER3, CCK4 contains a catalytically inactive tyrosine kinase domain, suggesting a potential tumor-characteristic role as a signal amplifier or modulator for an as yet unidentified kinase-competent partner.

Applications:
Suitable for use in Western Blot. Other applications have not been tested.

Recommended Dilution:
Western Blot: 1ug/ml
Optimal dilutions to be determined by the researcher.

Recommended Secondary Antibodies:
I1904-28C: IgG, H&L (HRP) Pab DkxGt
I1904-28G: IgG, H&L (HRP) (X-Adsorbed) Pab DkxGt

Storage and Stability:
Lyophilized powder may be stored at -20°C. Stable for 12 months at -20°C. Reconstitute with sterile PBS, 0.02% sodium azide. 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.
