Sample type: Serum

Sample species: Human

Sample dilution: No dilution

Review: I used this kit to detect the content of PTK7 in serum, and the standard curve was good, but the content in the sample serum was too small, which may be the reason why it was left for too long, so it could not be detected, and the product was fine.

Target Background

Function
(From Uniprot)
Inactive tyrosine kinase involved in Wnt signaling pathway. Component of both the non-canonical (also known as the Wnt/planar cell polarity signaling) and the canonical Wnt signaling pathway. Functions in cell adhesion, cell migration, cell polarity, proliferation, actin cytoskeleton reorganization and apoptosis. Has a role in embryogenesis, epithelial tissue organization and angiogenesis.
