Description
The L97-56 monoclonal antibody reacts with GATA4 (GATA-binding protein 4), a member of the GATA family of zinc finger-containing transcription factors that bind to the GATA nucleotide sequence. This ~50 kDa nuclear protein is expressed in mesodermal and definitive endodermal tissues such as the gastrointestinal tract, gonads, and heart. Genetic studies suggest that GATA4 regulates embryonic cardiac development in mice, and disruption of the GATA4 gene leads to defects in heart tube formation; in humans, GATA4 mutations are associated with atrial septal defects. In the adult heart, GATA4 regulates differentiated gene expression. The roles of GATA4 in endocrine and reproductive functions were recently reviewed.
Store undiluted at 4°C and protected from prolonged exposure to light. Do not freeze. The monoclonal antibody was purified from tissue culture supernatant or ascites by affinity chromatography. The antibody was conjugated to Alexa Fluor® 647 under optimum conditions, and unreacted Alexa Fluor® 647 was removed.
1. This reagent has been pre-diluted for use at the recommended Volume per Test. We typically use 1 × 10^6 cells in a 100-µl experimental sample (a test).
2. Alexa Fluor® 647 fluorochrome emission is collected at the same instrument settings as for allophycocyanin (APC).
3. Alexa Fluor® is a registered trademark of Molecular Probes, Inc., Eugene, OR.
4. The Alexa Fluor®, Pacific Blue™, and Cascade Blue® dye antibody conjugates in this product are sold under license from Molecular Probes, Inc. for research use only, excluding use in combination with microarrays, or as analyte specific reagents. The Alexa Fluor® dyes (except for Alexa Fluor® 430), Pacific Blue™ dye, and Cascade Blue® dye are covered by pending and issued patents.
5. Source of all serum proteins is from USDA inspected abattoirs located in the United States.
6. Caution: Sodium azide yields highly toxic hydrazoic acid under acidic conditions. Dilute azide compounds in running water before discarding to avoid accumulation of potentially explosive deposits in plumbing.
