Validation Data Gallery

  • The affinity of anti-human CTLA recombinant VHH towards human CTLA was determined using biolayer interferometry (BLI). Biotinylated, recombinant human CTLA  was immobilized on Streptavidin biosensors and assayed with 1.5 to 100 nM of FITC Plus conjugated-CTLA VHH (FITC-ctl). Fit indicates a 1:1 binding model fitted to the data.

ChromoTek CTLA4 VHH, recombinant binding protein for 2x Cys conjugation

Alpaca anti-CTLA4 VHH, purified recombinant binding protein. Suitable for for cysteine conjugation with thiol-reactive reagents, e.g. maleimides. Note: unconjugated VHHs are not suited for usage without prior labeling, since they contain reactive Cysteines. Shipment and storage buffers contain TCEP to keep Cysteins reduced.

BackgroundCTLA-4, also known as CD152, belonging to the immunoglobulin superfamily, is primarily found on activated T cells and regulatory T cells (Tregs). CTLA-4 is closely related to the T-cell costimulatory CD28, and both molecules bind to B7-1 and B7-2 on antigen-presenting cells. CTLA-4 acts as a negative regulatory molecule of T-cell responses. Besides the full-length transmembrane form, CTLA-4 also exists in a truncated soluble form (sCTLA-4).
