Target description

Transcription factor GATA-4 (UniProt: P43694; also known as GATA-binding factor 4) is encoded by the GATA4 gene (Gene ID: 2626) in human. The GATA family has six members that are divided into two subfamilies based on sequence similarity and expression profiles. GATA-1, -2, and -3 are expressed in hematopoietic cells and are involved in regulating proliferation and differentiation of blood cells and GATA-4, -5, and -6 are expressed in cardiac tissue. GATA-4 is a member of the highly conserved zinc-finger transcription factors with two GATA-type zinc fingers (aa 217-241 and 271-295) and plays a critical role in regulating differentiation, growth, and survival of a wide range of cell types. It binds to the consensus sequence 5′-AGATAG-3′ and plays a key role in cardiac development and function. In cooperation with T-Box Transcription Factor 5 (TBX5), it binds to cardiac super-enhancers and promotes cardiomyocyte gene expression, while it down-regulates endocardial and endothelial gene expression. It is also shown to be essential for normal testicular development. Higher expression of GATA-4 is observed the throughout embryonic development and postnatal growth. It functions as a critical regulator of cardiac differentiation. It is reported to function as a regulator of various cardiac genes, such as ANP, BNP, α-MHC, and β-MHC. Depletion of GATA-4 is shown to downregulate the expression of cardio regulators. Mutations in GATA4 gene are reported to cause Atrial septal defect 2 (ASD2) and ventricular septal defect 1 (VSD1) that are associated with defects in the cardiac conduction system and congenital cardiovascular anomalies. Gata4 knockout mouse embryos display septation defects, hypoplastic ventricular myocardium, and disrupted cardiac looping. Two isoforms of GATA-4 have been described that are produced by alternative splicing. This ZooMAb recombinant monoclonal antibody, generated by our proprietary technology, offers significantly enhanced specificity, affinity, reproducibility, and stability over conventional monoclonal.

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.
