产品评价
样品类型:血清
样品信息:人
稀释比:没有稀释
产品评价: 我用这款试剂盒做的血清中PTK7含量检测,标准曲线做的不错,但是样品血清中含量太少,可能是放太久的原因,所以未能检测到,产品没问题。

功能: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.
