RMA.Trh4 Db KO cells

This cell line overexpresses the ER-resident ceramide synthase Trh4 (transduced by CRISPR) and lacks the H2-Db gene. It serves as a control in helping to understanding T-cell recognition of the Trh4-derived peptide presented by the MHC class I molecule H2-Db.

Product description: This cell line overexpresses the ER-resident ceramide synthase Trh4 (transduced by CRISPR) and lacks the H2-Db gene. It serves as a control in helping to understanding T-cell recognition of the Trh4-derived peptide presented by the MHC class I molecule H2-Db. This peptide-epitope is a prototypic example of a neo-antigen selectively presented by cells with processing defects in the classical MHC class I (MHC-I) pathway. RMA cells have an intact processing pathway and a functional TAP peptide transporter, but overexpress the Trh4 protein and therefore could present the Trh4 peptide. However, no T cell recognition can be observed due to the absence of the MHC class I H2-Db.This population acts as a clear control. CRISPR edited RMA cells.
Production details: Retroviral transduction of the mouse Trh4 gene in an IRES-GFP construct and CRISPR/Cas9 technology
