The typical structure of a CAR molecule includes a single chain variable fragment (scFv), a spacer, a transmembrane domain (TM) and an intracellular signaling domain. The scFv is derived from monoclonal antibody (mAb), which can specifically recognize the target protein on tumor surface and subsequently transduct activation signal into CAR-T cell.
The chimeric antigen receptor (CAR), a major component of CAR-T, confers T-cell independent ability to recognize tumor antigens in an HLA-dependent manner, allowing CAR-engineered T cells to recognize broader targets compared to native T cell surface receptors. The basic design of CAR includes a tumor-associated antigen (TAA) binding region (usually derived from scFV segments of the monoclonal antibody antigen-binding region), an extracellular hinge region, a transmembrane region and an intracellular signal Area. The choice of the target antigen is a key determinant of the specificity and availability of CAR and the safety of the genetically modified T cells themselves.
CAR-T refers to Chimeric Antigen Receptor T-Cell Immunotherapy, which is a modification of the conventional T cell receptor TCR via a chimeric antigen receptor and is generally engineered into a monoclonal antibody antigen-binding domain. In the scFV segment, the modified CAR-T cells can specifically recognize tumor-associated antigens, and are not limited by MHC, so that the targeting, killing activity, and persistence of effector T cells are improved compared with conventional immune cells. CAR-T technology generally selects cytotoxic T lymphocytes (CTLs) for modification because CTLs recognize tumor antigens and release granzymes and perforin to kill tumors.
Diabody is a noncovalent dimer of single-chain Fv (scFv) fragment comprised of two chains expressed separately, each of which consists of a VH from one antibody and a VL from another antibody. https://www.creative-biolabs.com/bsab/category/diabody-29.htm

Notably, several CAR-T libraries have been generated not only for blood cancer antigen CD19, but also for solid tumors against different antigens, such as Her2, Her3, EGFR, FGFR1, VEGFR, etc. The selected stable clones can be used in clinic trials immediately, thus making this technology more powerful and attractive in chimeric antigen receptor t cell therapy. https://www.creative-biolabs.com/car-t/cellrapeutics-chimeric-antigen-receptor-car-technology.htm
Bispecific antibodies can recognize and bind two different antigens separately, so it can connect immune cells, viral molecules, etc. to tumor cells, thereby enhancing the killing effect on target cells, and it can also combines different antigens on the same tumor cell to enhance its binding specificity, thereby reducing side effects such as off-target toxicity. This bifunctional recombinant antibody has a higher therapeutic effect as a drug for treating tumors than a monoclonal antibody. https://www.creative-biolabs.com/bsab/
Get the right bispecific antibody as per your requirements. Creative Biolabs will perform the most suitable approach to fulfill your demands. Our team successfully produced all three types of bispecific antibodies using well-established methods.
It is usually identifiable or measurable in the blood, urine or other convenient body fluids by PCR, ELISA, and other conventional immune assays. In this sense, biomarkers can be categorized into genetic, epigenetic, proteomic, glycomic, and imaging biomarkers for cancer diagnosis, prognosis, and epidemiology.

The Chimeric antigen receptor CAR-T cell therapy has revolutionized the immunotherapy field with its high success rate against hematological diseases. Investigations in the early 1980s conceived the idea about tumor-infiltrating lymphocytes; however, reproducibility in invitro hampered further developments. It was not until 1993 Immunologist Dr. Zelig Eshhar created the first generation of chimeric T cells at the Weizmann Institute, Israel. The first-generation was successful during experiments, although not clinically effective. Since then, over three decades, a significant chunk of scientific intellect and considerable Research in cancer immunology has optimized this technology further.

Ordinary tumor therapeutic antibodies can only bind to a single antigen with a relatively low binding specificity is relatively low, which is prone to off-target effects. Bispecific antibodies (bsAbs) can recognize and bind two different antigens separately, so it can connect immune cells, viral molecules, etc. to tumor cells, thereby enhancing the killing effect on target cells, and it can also combine different antigens on the same tumor cell to enhance its binding specificity, thereby reducing side effects such as off-target toxicity.
Creative Biolabs' unique and highly sensitive Surfarray™ cell microarray technology focus on providing more details on receptor identification, targeted deconvolution, and specific screening of biotherapeutics such as CAR T cells and antibodies. https://www.creative-biolabs.com/car-t/surfarray-cell-microarray-technology.htm
Antigen specific T cell activation assay is one of the technologies we can provide during the one-stop service which can activate CAR-T cells for further downstream research or clinical trials. T cell activation requires at least two signals to be fully activated. The first signal is provided by the interaction of T cell antigen-specific receptor and the antigen-major histocompatibility complex (MHC). https://www.creative-biolabs.com/car-t/antigen-specific-t-cell-activation-assay.htm

Full-length monoclonal antibodies have been highly successful as therapeutic agents against various immune diseases and cancers. However, the large size severely limits their applications. As an alternative, single domain antibodies (sdAbs) present great advantages as novel therapeutic agents, such as small size, high expression, improved robustness, and a large number of accessible epitopes. Creative Biolabs is committed to providing customized proposals and solutions to develop novel sdAb-based therapeutics for disease treatment.

Single domain antibodies (sdAbs, or VHH) are the smallest antigen-binding units of antibodies, comprising either one variable domain or one engineered constant domain that solely facilitates target binding. They are popular as a novel class of proprietary therapeutic proteins containing unique structural and functional properties. At Creative Biolabs, we offer one-stop solutions for sdAb development and characterization to promote the identification of novel therapeutic sdAbs to meet your specific project demands. https://www.creative-biolabs.com/sdab/sdab-functional-identification.htm
