General description

We are committed to bringing you greener alternative products, which adhere to one or more of the 12 Principles of Green Chemistry. This antibody is preservative-free, produced without the harm or sacrifice of animals and exceptionally stable to allow for ambient shipping and storage if needed, and thus aligns with "Waste Prevention", "Designing Safer Chemicals" and "Design for Energy Efficiency". Click here for more information.
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 2H11 is a ZooMAb® rabbit recombinant monoclonal antibody that specifically detects Transcription factor 21 (TCF21). It targets an epitope within 17 amino acids from the N-terminal half.

Immunogen

KLH-conjugated linear peptide corresponding to 17 amino acids from the N-terminal half of human Transcription factor 21 (TCF21).

Application

Quality Control Testing

Evaluated by Western Blotting in HeLa cell lysate.

Western Blotting Analysis: A 1:10,000 dilution of this antibody detected TCF21 in HeLa cell lysate.

Tested Applications

Western Blotting Analysis: A 1:1,000 dilution from a representative lot detected TCF21 in A549 cell lysate.

Flow Cytometry Analysis: 0.1 µg from a representative lot detected TCF21 in one million A549 cells.

Immunohistochemistry (Paraffin) Analysis: A 1:100 dilution from a representative lot detected TCF21 in Human kidney tissue sections.

Affinity Binding Assay: A representative lot of this antibody bound TCF21 peptide with a KD of 3.1 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

Transcription factor 21 (UniProt: O43680; also known as TCF-21, Capsulin, Class A basic helix-loop-helix protein 23, bHLHa23, Epicardin, Podocyte-expressed 1, Pod-1) is encoded by the TCF21 (also known as BHLHA23, POD1) gene (Gene ID: 6943) in human. TCF21 is a transcription factor of the basic helix-loop-helix (bHLH) family that is involved in epithelial-mesenchymal interactions in kidney and lung morphogenesis that include epithelial differentiation and branching morphogenesis. It bHLH domain is localized in amino acids 79-131. Its efficient DNA binding requires dimerization with another bHLH protein. It forms a heterodimer with TCF3 and binds the E box (5′-CANNTG-3′). TCF21 is specific for mesoderm and is expressed in the embryo mesenchymal derived tissues, such as the epicardium. It is reported to play a vital role in regulating cell differentiation and cell fate specificity through epithelial-mesenchymal transformation during cardiac development. TCF21 is shown to disrupt the central SRF/MYOCD interaction via multiple mechanisms, suggesting that it may also serve a master regulatory function in promoting smooth muscle cells de-differentiation. 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. 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.
