NY-ESO-1-Specific TCR Lentivirus (Clone 1G4)

Products from BPS Bioscience require a minimum order value above 400€

Application: Use as a positive control for NY-ESO-1 TCR evaluation and optimize experimental conditions.Generate NY-ESO-1 TCR stable cell line (puromycin resistant).

Background: NY-ESO-1 (New York esophageal squamous cell carcinoma 1, also known as Cancer/testis antigen 1, or CTAG1B), is an important tumorigenic marker present in malignant cells. Normally expressed only in embryonic testis, this highly immunogenic protein is not usually found in normal tissues, but is re-expressed in multiple myeloma, non-small cell lung carcinoma, and breast and ovarian cancer, making it a promising candidate antigen for cancer immunotherapy.  Several NY-ESO-1-directed therapies are being developed including cancer vaccines, anti-NY-ESO-1 adoptive cell therapy, and NY-ESO-1-specific TCR-T cell therapy in combination with checkpoint inhibitors.

Description: The human NY-ESO-1-specific T Cell Receptor (TCR) lentiviruses (clone 1G4) are replication incompetent, HIV-based, VSV-G-pseudotyped lentiviral particles that are ready to infect almost all types of mammalian cells, including primary and non-dividing cells. These viruses transduce cells with a human TCR (clone 1G4) that specifically recognizes antigen NY-ESO-1 (New York esophageal squamous cell carcinoma 1), and in which the TCR α chain and β chain are linked by P2A. The lentiviruses also transduce a puromycin selection gene.Figure 1.

TRAV and TRAC correspond to the TCR alpha chain variable and constant regions, respectively, whereas TRBV and TRBC correspond to the TCR beta chain variable and constant regions.

Formulation: The lentiviruses were produced in HEK293T cells in medium containing 90% DMEM + 10% FBS.  Virus particles can be packaged in custom formulations by special request, for an additional fee.

Storage Stability: Lentiviruses are shipped with dry ice. For long term storage, it is recommended to store the virus at -80°C. Avoid repeated freeze-thaw cycles. Titers can drop significantly with each freeze-thaw cycle.

Supplied As: ≥2 x 10⁷ TU/ml. The titer will vary with each lot; the exact value is provided with each shipment.

Warnings: Avoid freeze/thaw cycles

Biosafety Level: BSL-2
