| Intruduction: | Human Neural Cell Adhesion Molecule L1 (L1CAM, also names as CD171) gene encodes a protein, which is involved in the dynamics of cell adhesion and in the generation of trans-membrane signals at tyrosine kinase receptors. During brain development, CD171 plays a critical role in multiple processes, including neuronal migration, axonal growth and fasciculation, and synaptogenesis. In the mature brain, CD171 controls the dynamics of neuronal structure and function, including synaptic plasticity. As an abundant cell surface molecule on neuroblastomas, targeting CD171 using CAR-T technology for childhood neuroblastoma is under clinical trial now.
Full-length extracellular domain of human CD171 cDNA (20 – 1120aa, Isoform-I, derived from BC126229) was constructed with codon optimization technology and expressed with a small T7-His-TEV cleavage site Tag (29aa) fusion at its N-terminal in E.coli as inclusion bodies. The final product was refolded using our unique “temperature shift inclusion body refolding” technology and chromatographically purified. |
