Descripción

Descripción general

ColorWheel^® technology is a novel and proprietary method of creating your own antibody and dye combinations for use in flow cytometry. By incubating any ColorWheel^® antibody with any ColorWheel^® dye, researchers can quickly and simply produce primary conjugated antibodies for use in single color or multicolor flow cytometry analysis. Each ColorWheel^® antibody and dye is lyophilized for long-term storage, allowing for simplicity and flexibility without compromise. ColorWheel^® technology requires both ColorWheel^® antibody and ColorWheel^® dye for Flow Cytometry application.

We are committed to bringing you greener alternative products, which adhere to one or more of The 12 Principles of Green Chemistry. This product is Preservative-free, lyophilized product for enhanced stability and allow for ambient shipping and thus aligns with "Waste Prevention", "Designing Safer Chemicals" and "Design for Energy Efficiency".

Aplicación

Quality Control Testing

Evaluated by Flow Cytometry in concanavalin A -stimulated BALB/c mouse splenocytes.

Flow Cytometry Analysis: One million BALB/c mouse splenocytes were stimulated with concanavalin A (3 µg/mL) for three days. Cells were fixed, permeabilized, and stained with APC conjugated anti-mouse CD4 clone RM4-5 and with 5 µL of a 1:1 mixture of Cat. No. CWA-1177, Anti-Mouse CD152/CTLA-4 (UC10-4F10-11) ColorWheel^® Dye-Ready mAb and Cat. No. CWDS-PE ColorWheel^® Antibody-Ready Phycoerythrin (PE) Dye or the equivalent amount of Cat. No. CWA-1014 Armenian Hamster IgG isotype control and Cat. No. CWDS-PE ColorWheel^® Antibody-Ready Phycoerythrin (PE) Dye. CD4 expressing cells also express CD152/CTLA-4.

Descripción de destino

Cytotoxic T-lymphocyte protein 4 (UniProt: P09793; also known as Cytotoxic T-lymphocyte-associated antigen 4, CTLA-4, CD152) is encoded by the Ctla4 (also known as Cd152) gene (Gene ID: 12477) in murine species. CTLA-4 is a single-pass type I, disulfide-linked homodimeric, membrane glycoprotein that is synthesized with a signal peptide (aa 1-35), which is subsequently cleaved off to produce the mature protein that contains an extracellular domain (aa 36-161), a transmembrane domain (aa 162-182), and a cytoplasmic domain (aa 183-223). Its homodimerization domains are localized in amino acids 46-50 and 150-155. N-glycosylation of asparagine 108, 113, and 145 is essential for dimerization. CTLA-4 is widely expressed with highest expression observed in lymphoid tissues. Its expression is not observed in naïve CD+ or CD8+ T cells but is rapidly up-regulated and trafficked to the cell surface following TCR-mediated T-cell activation. It binds to two ligands, CD80 (B7-1) and CD86 (B7-2), which are shared with CD28. However, its affinity for CD80 and CD86 is significantly higher. Amino acids 134-139 are reported to be important for its interaction with CD80 and CD86. It serves as an inhibitory receptor acting as a major negative regulator of T-cell responses and controls peripheral tolerance and the development of autoimmunity. It interferes with the ability of T-cells to form stable conjugates with antigen-presenting cells (APCs). CTLA-4 plays a key role in restraining the adaptive immune response of T-cells towards a variety of antigens including tumor associated antigens. (Ref.: Brunner-Weinzierl, MC., and Rudd, CE (2018).
