General description
ZooMAb® antibodies represent an entirely new generation of recombinant monoclonal antibodies. Each ZooMAb® antibody is manufactured using our proprietary recombinant expression system, purified to homogeneity, and precisely dispensed to produce robust and highly reproducible lot-to-lot consistency. Only top-performing clones are released for use by researchers. Each antibody is validated for high specificity and affinity across multiple applications, including its most commonly used application. ZooMAb® antibodies are reliably available and ready to ship when you need them.
Specificity
Clone 1I14 is a ZooMAb® Rabbit recombinant monoclonal antibody that specifically detects CD103. It targets an epitope within 25 amino acids from the N-terminal region.
Immunogen
KLH-conjugated linear peptide corresponding to 25 amino acids from the N-terminal region of human CD103.
Application
Quality Control Testing
Evaluated by Western Blotting in Jurkat cell lysate.
Western Blotting Analysis: A 1:1,000 dilution of this antibody detected CD103 in Jurkat cell lysate.
Tested Applications
Western Blotting Analysis: A 1:1,000 dilution from a representative lot detected His-tagged, recombinant human CD103 (Integrin E) and β7.
Flow Cytometry Analysis: 1 µg from a representative lot detected CD103 in one million Jurkat cells.
Affinity Binding Assay: A representative lot of this antibody bound CD103 peptide with a KD of 3.2 x 10-7 in an affinity binding assay.
Note: Actual optimal working dilutions must be determined by end user as specimens, and experimental conditions may vary with the end user.

Target description
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 that 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. This ZooMAb® recombinant monoclonal antibody, generated by our propriety technology, offers significantly enhanced specificity, affinity, reproducibility, and stability over conventional monoclonals (Ref.: Uss, E., et al. (2006). J. Immunol., 177(5); 2775-2783; Kruschwitz, M., et al. (1991). J. Clin. Pathol. 44(8); 636-645).
Physical form
Purified recombinant rabbit monoclonal antibody IgG, lyophilized in PBS with 5% Trehalose, normal appearance a coarse or translucent resin. The PBS/trehalose components in the ZooMAb formulation can have the appearance of a semi-solid (bead like gel) after lyophilization. This is a normal phenomenon. Please follow the recommended reconstitution procedure in the data sheet to dissolve the semi-solid, bead-like, gel-appearing material. The resulting antibody solution is completely stable and functional as proven by full functional testing. Contains no biocide or preservatives, such as azide, or any animal by-products. Larger pack sizes provided as multiples of 25 µL.
Reconstitution
300 µg/mL after reconstitution at 25 µL per vial. Please refer to guidance on suggested starting dilutions and/or titers per application and sample type.
Storage and Stability
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 filtered lab grade water or PBS; Reconstituted antibodies can be stored at 2-8°C, or -20°C for long term storage. Avoid repeated freeze-thaws.
