产品详细信息

Description
The 2E7 monoclonal antibody reacts with mouse CD103, the alphaE integrin. CD103 non-covalently associates with integrin beta7 and is expressed on all intraepithelial lymphocytes, a small subset of peripheral lymphocytes, and dendritic epidermal T cells (DEC). Epithelial cell antigen E-cadherin binds to CD103 and mediates homing of lymphocytes to the intestinal epithelium.

Applications Tested
This 2E7 antibody has been tested by flow cytometric analysis of mouse lymph node cells. This may be used at less than or equal to 1.0 µg per test. A test is defined as the amount (µg) of antibody that will stain a cell sample in a final volume of 100 µL. Cell number should be determined empirically but can range from 10^5 to 10^8 cells/test. It is recommended that the antibody be carefully titrated for optimal performance in the assay of interest.

Blocking Buffers
When using two or more Super Bright, Brilliant Violet™, Brilliant Ultra Violet™, or other polymer dye-conjugated antibodies in a staining panel, it is recommended to use Super Bright Complete Staining Buffer (Product # SB-4401) or Brilliant Stain Buffer (Product # 00-4409-75) to minimize any non-specific polymer interactions. Please refer to the datasheet for Super Bright Staining Buffer or Brilliant Stain Buffer for more information.

Fixation
• Samples can be stored in IC Fixation Buffer (Product # 00-8222) (100 µL of cell sample + 100 µL of IC Fixation Buffer) or 1-step Fix/Lyse Solution (Product # 00-5333) for up to 3 days in the dark at 4°C with minimal impact on brightness and FRET efficiency/compensation.
• Some generalizations regarding fluorophore performance after fixation can be made, but clone specific performance should be determined empirically.

靶标信息

CD103, also known as ITGAE or Integrin alpha E, is a molecule that non-covalently associates with integrin beta 7 to form a heterodimeric integral membrane protein. This protein is part of the integrin family, characterized by an alpha chain and a beta chain. Specifically, CD103 includes a 150 kDa alpha chain and a 120 kDa beta chain, with the alpha integrin undergoing post-translational cleavage in the extracellular domain to yield disulfide-linked heavy and light chains. CD103 is primarily expressed on mucosa-associated T lymphocytes, intraepithelial lymphocytes (IELs), and activated cells, as well as a subset of TGF beta-1 cells. It is preferentially found in human intestinal IELs, where it plays a role in adhesion and may serve as an accessory molecule for IEL activation. CD103 binds to epithelial cell antigen E-cadherin, mediating the homing of lymphocytes to the intestinal epithelium. In peripheral blood and lymphoid organs, CD103 is expressed by 0.5 to 2% of resting lymphocytes, and its expression can be upregulated in vitro by stimulating human T cells with mitogens. CD103 is also expressed by hairy cell leukemia (HCL) and some chronic B cell lymphocytic leukemias. The CD103 antibody stains a few bone marrow cells and, rarely, peripheral blood lymphocytes. Diseases associated with CD103 dysfunction include hairy cell leukemia and splenic marginal zone lymphoma.
