Anti-CCK4, NT (Tyrosine-protein Kinase-like 7, Colon Carcinoma Kinase-4, CCK-4, Protein-tyrosine Kin

PTK7 may function as a cell adhesion molecule. Although it belongs to the insulin receptor subfamily of Tyr protein kinases, it likely lacks the catalytic activity of a tyrosine kinase. It may be connected to the pathophysiology of colon carcinomas and/or may represent a tumor progression marker. This Type I membrane protein is highly expressed in lung, liver, pancreas, kidney, placenta and melanocytes, and it is weakly expressed in thyroid gland, ovary, brain, heart and skeletal muscle, and not in colon. Expression is also detected in erythroleukemia cells. Applications: Suitable for use in ELISA and Immunohistochemistry. Other applications not tested. Recommended Dilution: ELISA: 1:1,000, Immunohistochemistry: 1:50-1:100, Optimal dilutions to be determined by the researcher. Storage and Stability: May be stored at 4°C for short-term only.
