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 1J11 is a ZooMAb rabbit recombinant monoclonal antibody that specifically detects Smad3. It targets an epitope with in 15 amino acids from the N-terminal region.

Immunogen

KLH-conjugated linear peptide corresponding to 15 amino acids from the N-terminal region of human Smad3.

Application

Anti-Smad3, clone 1J11 ZooMAb, Cat. No. ZRB1005, is a recombinant Rabbit Monoclonal Antibody that specifically targets Smad3 and has been tested for use in Immunocytochemistry, Immunohistochemistry (Paraffin), and Western Blotting.
Western Blotting Analysis: A 1:1,000 dilution from a representative lot detected Smad3 in NIH3T3 and HEK293 cell lysate.

Immunohistochemistry (Paraffin) Analysis: A 1:1,000 dilution from a representative lot detected Smad3 in human kidney and mouse colon tissue sections.

Immunocytochemistry Analysis: A 1:5,000 dilution from a representative lot detected Smad3 in HT1080 cells.

Target description

Mothers against decapentaplegic homolog 3 (UniProt: P84022; also known as MAD homolog 3, Mad3, Mothers against DPP homolog 3, hMAD-3, JV15-2, SMAD family member 3, SMAD 3, Smad3, hSMAD3) is encoded by the SMAD3 (also known as MADH3) gene (Gene ID: 4088) in human. Smad3 is a receptor-regulated SMAD (R-SMAD) that serves as an intracellular signal transducer and transcriptional modulator activated by TGF-beta and activin type 1 receptor kinases. It binds the TRE element in the promoter region of many genes that are regulated by TGF-beta. In the absence of TGF-beta it is mainly cytoplasmic and with TGF-beta stimulation it translocates to the nucleus in complex with Smad4. In the absence of TGF-beta it is present in a monomeric form and homooligomerizes in the presence of TGF-beta. It can also form a heterotrimer with Smad2 or Smad4 upon C-terminally phosphorylated Smad2 or Smad4. Smad3 is phosphorylated on threonine 179 and serine 204 and 208 on EGF and TGF-beta treatment. Serine 208 is shown to be the main site of MAPK-mediated phosphorylation. Smad3 is also phosphorylated on serine residues in the C-terminal SXS motif by TGFBR1 and ACVR1. TGFBR1-mediated phosphorylation at these C-terminal sites is required for its interaction with SMAD4, nuclear location, and transactivational activity. Through the action of the phosphatase PPM1A, Smad3 is released from the Smad2 or Smad4 complex, and exported out of the nucleus by interaction with RANBP1. This ZooMAb recombinant monoclonal antibody, generated by our propriety technology, offers significantly enhanced specificity, affinity, reproducibility, and stability over conventional monoclonals.

Physical form

Purified recombinant rabbit monoclonal antibody IgG, lyophilized in PBS with 5% Trehalose, normal appearance a coarse or translucent resin. 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. 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.
