Anti-Human CD103 (Ber-ACT8) ColorWheel^® Dye-Ready mAb

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".

Clone Ber-ACT8 is a mouse monoclonal antibody that detects Integrin alpha-E (CD103). It targets an epitope within the extracellular domain.

HTLV-1 induced human MAPS16 T cells

Quality Control Testing:

Evaluated by Flow Cytometry in 7-day PHA-stimulated human PBMCs.

Flow Cytometry Analysis (FC): Staining of one million 7-day PHA-stimulated Human peripheral blood mononuclear cells (PBMC) was performed using 5 μL of a 1:1 mixture of Cat. No. CWA-1065, Anti-Human CD103 (Ber-ACT8) ColorWheel^® Dye-Ready mAb and Cat. No. CWD-PE ColorWheel^® Antibody-Ready Phycoerythrin (PE) Dye or an 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

Integrin alpha-E (UniProt: P38570; also known as HML-1 antigen, Integrin alpha-IEL, Mucosal lymphocyte 1 antigen, CD103) is encoded by the ITGAE gene (Gene ID: 3682) in human. Integrin alpha-E (CD103) is a single-pass type I membrane protein that is synthesized with a signal peptide (aa 1-18), which is subsequently cleaved off to generate the mature form that contains an extracellular domain (aa 19-1124), a transmembrane domain (aa 1125-1147), and a short cytoplasmic domain (aa 1148-1179). It is expressed on a subclass of T-lymphocytes known as intra-epithelial lymphocytes which are located between mucosal epithelial cells. CD103 expression has been reported on CD4+ regulatory T cells and about 4% of circulating CD8+ T cells also bear the CD103 molecule. Expression of CD103 on alloreactive cells is shown to be augmented by IL-4, IL-10, or TGF-β and decreased by addition of IL-12. It forms a heterodimer with β-7 subunit to form a receptor for E-cadherin and mediate adhesion of intra-epithelial T cells to epithelial cell monolayers. Clone Ber-ACT8 is shown to react with in vitro activated T cells and a small subset of normal resting T cells, but not with resting B cells or several other human cell lines. Its reactivity is restricted to a few T cells in the peripheral blood, the extrafollicular areas of lymph nodes and tonsils, and splenic red pulp. (Ref.: Uss, E., et al. (2006). J. Immunol., 177(5); 2775-2783; Kruschwitz, M., et al. (1991). J. Clin. Pathol. 44(8); 636-645).

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.

Recommend storage of lyophilized product at 2-8°C. 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.
