Background: CD19 (also known as Cluster of Differentiation 19, B-lymphocyte surface antigen B4, or CVID3) is a glycoprotein expressed at the surface of B lymphocytes through most phases of B cell maturation. It is strictly required for B cell terminal differentiation. Mutations in the CD19 gene cause severe immune-deficiency syndromes associated with impaired antibody production such as CVID3 (common variable immuno-deficiency 3). The majority of B cell malignancies express normal to high levels of CD19, making it a nearly ideal target for cancer immunotherapy. Blinatumomab, a CD19/CD3 bi-specific T cell engager (BiTE) has been approved for relapsed/refractory B precursor ALL (Acute lymphoblastic leukemia) and CD19 was the target of the first approved CAR-T cell therapy. Studies of CD19 function and expression profiles will continue to broaden our knowledge and support broader applications in cancer therapy.

Description: The anti-CD19 CAR lentiviruses are replication incompetent, HIV-based, VSV-G pseudotyped lentiviral particles that are ready to ready to transduce most mammalian cells, including primary and non-dividing cells. These viruses transduce the ScFv portion of anti-CD19 (clone FMC63) linked to 2nd generation CAR (Chimeric Antigen Receptor), containing CD8 hinge and transmembrane domains, 4-1BB and CD3ζ signaling domains. This construct also includes an IRES- enhanced green fluorescent protein (eGFP) sequence downstream of anti-CD19 CAR cassette to facilitate analysis and sorting of transduced cells.Note: This product transduces the same anti-CD19 CAR construct (CD19 ScFv-CD8-4-1BB-CD3ζ) as other available anti-CD19 CAR Lentiviruses (BPS Bioscience #78600, 78601 and 78602), but differ in key aspects. This product contains an eGFP reporter/selection marker so the transduced cells can be sorted based on eGFP expression.

Formulation: The lentiviruses were produced from HEK293T cells, concentrated, and resuspended in DMEM. 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: 50 µl of anti-CD19 CAR at a titer ≥ 3x10⁸ 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
