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 M38 is a mouse monoclonal antibody that detects CD81 (TSPAN-28). I targets an epitope within the extracellular domain.

MOLT-4 cells.

Quality Control Testing:

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

Flow Cytometry Analysis (FC): Staining of one million Human peripheral blood mononuclear cells (PBMC) was performed using 5 μL of a 1:1 mixture of Cat. No. CWA-1066, Anti-Human CD81 (M38) 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.

CD81 antigen (UniProt: P60033; also known as 26 kDa cell surface protein TAPA-1, Target of the antiproliferative antibody 1, Tetraspanin-28, Tspan-28, CD81) is encoded by the CD81 (also known as TAPA1, TSPAN28) gene (Gene ID: 975) in human. CD81 is a nonglycosylated, homodimeric, multi-pass membrane protein of the tetraspanin (TM4SF) family. It is expressed in a wide range of cells, including hematolymphoid, neuroectodermal, and mesenchymal tumor cell lines and is reported to play a role in the regulation of lymphoma cell growth. It contains four transmembrane domains, two extracellular loops, and short amino and carboxyl termini that are intracellular. CD81 is shown to affect cell adhesion, morphology, activation, proliferation, and differentiation of B, T, and other cells. On B cells it is a part of a complex involving CD21, CD19, and Leu13 and this complex is reported to reduce the threshold for B cell activation via the B cell receptor by bridging antigen specific recognition and CD21-mediated complement recognition. On T cells, it is shown to associate with CD4 and CD8 and provides a costimulatory signal with CD3. It is also reported to act as a receptor for hepatitis C virus (HCV) in hepatocytes. Mutations in CD81 gene cause common variable immunodeficiency 6 (CVID6) that is characterized by antibody deficiency, hypogammaglobulinemia, recurrent bacterial infections, and an inability to mount an antibody response to antigen.

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.
