Description

Description générale

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 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".

Spécificité

Clone RPA-T8 is a mouse monoclonal antibody that detects human T-cell surface glycoprotein CD8 alpha chain (CD8a).

Application

Quality Control Testing:

Evaluated by Flow Cytometry in human peripheral blood mononuclear cells (PBMC).

 Staining of one million Human peripheral blood mononuclear cells (PBMC) was performed using 5 μL of a 1:1 mixture of Cat. No. CWA-1035, Anti-Human CD8a (RPA-T8) ColorWheel^® Dye-Ready mAb and Cat. No. CWD-PE ColorWheel^® Antibody-Ready Phycoerythrin (PE) Dye or an equivalent amount of PE-conjugated Mouse IgG1 isotype control.

Note: Actual optimal working dilutions must be determined by end user as specimens, and experimental conditions may vary with the end user

Description de la cible

T-cell surface glycoprotein CD8 alpha chain (UniProt: P01732; also known as T-lymphocyte differentiation antigen T8/Leu-2, CD8a) is encoded by the CD8A (also known as MAL) gene (Gene ID: 925) in human. CD8 alpha is a single-pass type I membrane glycoprotein that is synthesized with a signal peptide (aa 1-21), which is subsequently cleaved to form the mature protein that has an extracellular domain (aa 22-182), a helical domain (aa 183-203), and a cytoplasmic tail (aa 204-235). CD8 is generally present as a heterodimer of alpha and beta chains linked by two disulfide bonds, however, it can also form homodimers. The CD8 alpha/alpha homodimer is expressed on a subset of gamma/delta TCR-bearing T cells, NK cells, intestinal intraepithelial lymphocytes, and lymphoid dendritic cells. CD8a homodimer is also reported to promote the survival and differentiation of activated lymphocytes into memory CD8 T-cells. CD8a plays an essential role in the immune response and serves multiple functions in responses against both external and internal offenses. In T-cells, it functions primarily as a coreceptor for MHC class I molecule:peptide complex. It interacts simultaneously with the T-cell receptor (TCR) and the MHC class I proteins presented by antigen presenting cells. In turn, it recruits the Src kinase LCK to the vicinity of the TCR-CD3 complex where LCK phosphorylates various substrates leading to lymphokine production, motility, adhesion, and activation of cytotoxic T-lymphocytes (CTLs). This process enables CTLs to recognize and eliminate infected cells and tumor cells. (Ref.: Harland, KL., et al., (2014). Nat. Commun. 5; Article 3547; Gibbings, DJ., et al. (2007). BMC Immunol. 8; 12).

Forme physique
