Anti-ETL1 antibodies are used in antigen-specific immunodetection in biological samples. The target ETL1 is a known alias name of the protein leucine rich glioma inactivated 1, encoded by the LGI1 gene in humans. This 557-amino acid residue protein is reported to regulate voltage-gated potassium channels assembled from KCNA1, KCNA4 and KCNAB1. It is localized to the ER, Golgi, cytoplasm, and is secreted of the cell and features glycosylated post-translational modifications. In terms of tissue expression, it is reported to be highly expressed in the neural tissues, especially in the brain.
