A uniCAR [Anti-FITC scFv-BBζ], with a CAR Adaptor [Anti-CD20 Antibody (1F5), FITC Labled], a Anti-FITC CAR System (CAR-NR-ZP1034)

Fluorescein isothiocyanate (FITC) is a synthetic dye that is physiologically deficient in human body and has been used widely as a flowcytometry marker to label antibodies. The anti-FITC CAR contains two essential elements, one is a FITC-tagged tumor-targeting switch molecule and the other is a transmembrane CAR with an anti-FITC scFv. The FITC-labeled switch molecules form a pseudo-immunological synapse between anti-FITC CAR T cells and tumor cells expressing a given antigen, such as folate receptor or CD19, leading to lysis of the corresponding tumor cells.

Creative Biolabs provides customized Anti-FITC CAR design and construction services. Please contact us for more detailed information.

  • Discription of Signaling Cassetes
  • 41BB
    CD137 (also known as 4-1BB) is a surface co-stimulatory glycoprotein originally described as present on activated T lymphocytes, which belongs to the tumor necrosis factor (TNF) receptor superfamily. It is expressed mainly on activated CD4+ and CD8+ T cells, and binds to a high-affinity ligand (4-1BBL) expressed on several antigen-presenting cells such as macrophages and activated B cells. On the basis of preclinical observation, this molecule can promote the persistence of antigen-specific and antigennonspecific chimeric antigen receptor T-cells to significantly increases antitumor activity.
    CD3ζ
    CD3ζ, also known as T-cell receptor zeta, which together with T-cell receptor and CD3γ, δ , ε chain, forms the TCR-CD3 complex. ζ was expressed independently from the complex. The zeta chain plays an important role in coupling antigen recognition to several intracellular signal-transduction pathways. CD3-zeta, which contains 3 ITAMs, is the most commonly used endodomain component of CARs. It transmits an activation signal to the T cell after antigen is bound. CD3-zeta may not provide a fully competent activation signal and additional co-stimulatory signaling is needed. For example, chimeric 4-1BB and OX40 can be used with CD3-zeta to transmit a proliferative/survival signal, or all three can be used together.
