T2 Cells

The T2 cell line is a derivative of the T1 human lymphoblastoid cell line and is characterized by its unique properties related to antigen processing and presentation. These cells are deficient in the transporter associated with antigen processing (TAP), resulting in the inability to effectively transport peptides into the endoplasmic reticulum for loading onto major histocompatibility complex (MHC) class I molecules. This deficiency makes T2 cells particularly valuable in immunological research, especially in studies related to the presentation of antigens and the function of MHC class I molecules. By using T2 cells, researchers can better understand the mechanisms of immune recognition and the role of TAP in antigen presentation. T2 cells are also known for their application in cytotoxic T lymphocyte (CTL) assays. Due to their TAP deficiency, these cells express very low levels of surface MHC class I molecules unless exogenous peptides are added. This property allows for the precise study of peptide-MHC interactions and the evaluation of CTL responses to specific antigens. Furthermore, T2 cells are used in vaccine development research, particularly in designing strategies that enhance the presentation of antigens to the immune system. Their unique characteristics make T2 cells a crucial tool in both basic and applied immunology research. Hybrid cell lines, Growth Conditions: Suspension, Biosafety level: BSL 2
