Abnormally high expression of programmed death-ligand 1 (PD-L1) on tumor cells and antigen-presenting cells in the tumor microenvironment mediates tumor immune escape, since PD-L1 binding to its receptor, programmed death-1 (PD1) on the surface of T

The claudin 18.2 IHC kit is intended to detect claudin 18.2 protein in formalin-fixed, paraffin-embedded (FFPE) tissue sections in vitro by IHC and to assist in the identification of malignant tumor patients who benefit from the treatment with target

Mismatch Repair (MMR) occurs in the process of DNA replication, recombination and damage repair, and can recognize and repair erroneous insertions, deletions and integrations. Four common mismatch repair proteins in the human body, namely hMLH1, hMSH

The c-MET gene encodes a tyrosine kinase-type receptor, and its ligand is hepatocyte growth factor (HGF). c-MET is the only known HGF high-affinity receptor. HGF activates c-MET after binding to c-MET, which causes cell proliferation, migration, diff
