CAR negative control: 4-1BB-CD3ζ (Puro)


SKU: CAR-Ctr1 Category:


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

CAR control lentivector map

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.

CD3ζ (T-cell receptor zeta) is expressed by T cells and NK cells. It together with T-cell receptor and CD3γ, δ, ε chain, forms the TCR-CD3 complex. CD3-zeta is the most commonly used activation component of CARs. It transmits an activation signal to the T cell after the antigen is bound. It can be coupled with additional co-stimulatory signaling for the complete activation.

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.
