CAR negative control: Anti-CD19-ScFv-4-1BB (Puro)


SKU: CAR-Ctr2 Category:


Pre-made CAR Negative Control Lentivirus express the Anti-CD19 CAR construct of “anti-CD19-ScFV (VL-VH)-CD8 hinge-4-1BB”, containing Puromycin (Puro) selection. It has the entire ANti-CD19 CAR construct except the CD3ζ activation domain, thus serving as the negative control to validate the specificity of the Anti-CD19 (4-1BB) CAR-T targeted killing.   The lentivector’s core structure is represented by the scheme below. see details in Product Manual.

CAR control lentivector map

CD19 is a marker of in most B cell leukemias and lymphomas but not in any normal tissue other than the B cell lineage, CD19 is used to diagnose cancers that arise from this type of cell, and is used as the target for CD19-targeted therapies.

4-1BB (CD137) is a surface glycoprotein present on activated T Lymphocytes, CD4+ and CD8+ T cells. It binds to its ligand expressed on antigen-presenting cells (macrophages and activated B cells). It promotes T-cell antitumor activity. 4-1BB is one of the most widely studied co-stimulatory domain used in CAR design.

Amount: 200 ul/vial at titer of 1×108 IFU/ml, concentrated lentivirus provided in PBS solution, premixed with 10x polybrene (60ug/ml), premade, ready to ship, in dry-ice package.
