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.

Clone APA1/1 is a mouse monoclonal antibody that detects T-cell surface glycoprotein CD3 epsilon chain (CD3 epsilon). It targets an epitope within the activation motif.

SDS denatured CD3 epsilon from human thymus.

Quality Control Testing:

Evaluated by Flow Cytometry in Jurkat cells.

Flow Cytometry Analysis (FC): Staining of one million Jurkat cells was performed using 5 μL of a 1:1 mixture of Cat. No. CWA-1064, Anti-Human CD3e (APA1/1) 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

Lyophilized from PBS containing D-Mannitol and Sucrose, normal appearance is a dried pellet. Reconstituted antibody solution is stable and functional as assessed by functional testing. Contains no biocide or preservatives, such as azide.

1.0 mg/mL after reconstitution at 25 μL in PBS. Please refer to guidance on suggested starting dilutions and/or titers per application and sample type.

T-cell surface glycoprotein CD3 epsilon chain (UniProt: P07766; also known as T-cell surface antigen T3/Leu-4 epsilon chain, CD3e) is encoded by the CD3E (also known as T3E) gene (Gene ID: 916) in human. CD3 is a single-pass type I membrane protein that is a part of the TCR-CD3 complex present on T-cells and plays an essential role in adaptive immune response. The TCR-CD3 complex is formed through noncovalent association of TCR with a CD3 signalling apparatus consisting of the  γ, δ, ε and ζ subunits. In addition of this role of signal transduction in T-cell activation, CD3ε plays an essential role in correct T-cell development. It participates also in internalization and cell surface down-regulation of TCR-CD3 complexes via endocytosis sequences present in CD3 cytosolic region. CD3ε is synthesized with a signal peptide (aa 1-22), which is subsequently cleaved off to generate the mature form that contains an extracellular domain (aa 23-126), a transmembrane protein (aa 127-152), and a cytoplasmic domain (aa 153-207). The CD3 complex performs two major functions. Firstly, CD3 chains are required for intracellular signaling where tyrosines in its immunoreceptor tyrosine-based activation motif (ITAM) domain (aa 178-205) are phosphorylated by Lck. Secondly, the CD3 complex is involved in TCR surface expression. In the endoplasmic reticulum, the TCR heterodimer physically associate with the CD3 complex prior to moving to the Golgi for glycosylation and subsequently translocating to the T-cell surface. Mutations in CD3E gene are known to cause immunodeficiency 18 (IMD18) that is characterized by recurrent infections in infancy or early childhood with variable severity. (Ref.: Dong, D., et al. (2019). Nature. 573(7775); 546-552).

Recommend storage of lyophilized product at 2-8℃. Before reconstitution, micro-centrifuge vials briefly to spin down material to bottom of the vial. Reconstitute each vial by adding 25 μL of PBS. Protect from light.
