分子別名（Synonym）
NECTIN4,LNIR, PRR4, PVRL4
表達區(qū)間及表達系統(tǒng)（Source）
Biotinylated Human Nectin-4 Protein, His,Avitag (NE4-H82E3) is expressed from human 293 cells (HEK293). It contains AA Gly 32 - Ser 243 (Accession # Q96NY8-1).
Predicted N-terminus: His
蛋白結構（Molecular Characterization）
This protein carries a polyhistidine tag at the N-terminus and an Avi tag (Avitag?) at the C-terminus.
The protein has a calculated MW of 26.7 kDa. The protein migrates as 30-35 kDa when calibrated against Star Ribbon Pre-stained Protein Marker under reducing (R) condition (SDS-PAGE) due to glycosylation.
標記（Labeling）
Biotinylation of this product is performed using Avitag? technology. Briefly, the single lysine residue in the Avitag is enzymatically labeled with biotin.
蛋白標記度（Protein Ratio）
Passed as determined by the HABA assay / binding ELISA.
內毒素（Endotoxin）
Less than 1.0 EU per μg by the LAL method.
純度（Purity）
>90% as determined by SDS-PAGE.
制劑（Formulation）
Lyophilized from 0.22 μm filtered solution in PBS, pH7.4 with trehalose as protectant.

背景（Background）
Nectin-4(Nectin cell adhesion molecule 4) is a Nectin and nectin-like family of cell adhesion molecules. It is found in high levels in normal embryonic and fetal tissues, but decreases after adulthood and is limited in distribution in healthy tissues. Nectin-4 is overexpressed in a variety of tumor cells and promotes tumor cell growth and proliferation. Solid tumors with high expression of Nectin-4 include bladder cancer, pancreatic cancer, triple negative breast cancer, non-small cell lung cancer, stomach cancer, esophageal cancer, ovarian cancer and many other cancers. Studies have found that Nectin-4 promotes tumor cell proliferation, differentiation, migration and invasion by activating the PI3K/Akt pathway, and is believed to play an important role in the occurrence and metastasis of cancer. It is based on these research backgrounds that drug research targeting this target has emerged.
