Human neural cell adhesion molecule L1 (L1CAM) amino acids 20-1120 carrying an N-terminal 10xHis-tag and a C-terminal Myc-tag were expressed in mammalian cells. The product is the recombinant human L1CAM protein. This L1CAM protein is characterized by high purity (>95%, SDS-PAGE) and low endotoxin (1.0 EU/ug protein, LAL method). It is an active protein. Its activity was determined via a functional ELISA by binding to the anti-L1CAM rabbit monoclonal antibody, with EC50 values of 5.384-9.380 ng/ mL. It is available now.

L1CAM mainly functions during neural development, including the regulation of neurite outgrowth, fasciculation, cell adhesion, cell migration, myelination, and cell survival. It is also involved in cancer development and is related to metastases and poor prognosis.

Applications : Antigen, ELISA standard and its raw materials

Review: After receiving the product, we conducted ELISA experiments with antigen and antibody, and the EC50 was 4.290-7.817ng/ml, which showed good binding activity and can be used for subsequent immune and antibody screening. The subsequent experiment progressed smoothly, and the results were stable.

Target Background

Neural cell adhesion molecule involved in the dynamics of cell adhesion and in the generation of transmembrane signals at tyrosine kinase receptors. During brain development, critical in multiple processes, including neuronal migration, axonal growth and fasciculation, and synaptogenesis. In the mature brain, plays a role in the dynamics of neuronal structure and function, including synaptic plasticity.

  1. In uterine carcinosarcoma, membranous L1CAM expression was positive in the epithelial component in 65.4% of cases. Remarkably, expression was negative in the mesenchymal component. In cases where both components were intermingled, expression limited to the epithelial component was confirmed by a double stain for L1CAM and keratin. Expression of L1CAM did not relate to overall or disease-free survival. PMID: 30140948
