Anti-GATA4 Antibody

GATA4 (GATA binding factor-4) is a member of the GATA family of transcription factors. GATA4 is involved in embryogenesis and in myocardial differentiation and function and is associated with heart septal defects.

Recognizes GATA4.

Synthetic peptide corresponding to amino acids 313-331 of human GATA4 (RKRKPKNLNKSKTP).

Detect GATA4 with Anti-GATA4 Antibody (Rabbit Polyclonal Antibody), that has been shown to work in ICC & WB.

ImmunoAffinity Purified

Affinity Purified immunoglobulin precipitated in a solution of 50% saturated ammonium sulfate and PBS containing no preservatives.

Maintain unopened vial at -20°C for up to 6 months. Avoid repeated freeze/thaw cycles.

The rehydrated antibody solutions can be stored undiluted at 2–8°C for 2 months without any significant loss of activity. Note, the solution is not sterile, thus care should be taken if product is stored at 2–8°C.

For storage at -20°C, the addition of an equal volume of glycerol can be used, however, it is recommended that ACS grade or higher glycerol be used, as significant loss of activity can occur if the glycerol used is not of high quality.

For freezing, it is recommended that the rehydrated antibody solution be further diluted 1:1 with a 2% BSA (fraction V, highest-grade available) solution made with the rehydration buffer. The resulting 1% BSA/antibody solution can be aliquoted and stored frozen at -70°C for up to 6 months. Avoid repeated freeze/thaw cycles.

PREPARATION AND USE:

To reconstitute the antibody, centrifuge the antibody vial at moderate speed (5,000 rpm) for 5 minutes to pellet the precipitated antibody product. Carefully remove the ammonium sulfate/PBS buffer solution and discard. It is not necessary to remove all of the ammonium sulfate/PBS solution: 10 μL of residual ammonium sulfate solution will not effect the resuspension of the antibody. Do not let the protein pellet dry, as severe loss of antibody reactivity can occur.

Resuspend the antibody pellet in any suitable biological buffer, standard PBS or TBS (pH 7.3–7.5) are typical. Volumes required are not critical but it is suggested that the final antibody concentration be between 0.1 mg/mL and 1.0 mg/mL. For example, to achieve a1 mg/mL concentration with 50 μg of precipitated antibody, the amount of buffer needed would be 50 μL.

Carefully add the liquid buffer to the pellet. DO NOT VORTEX. Mix by gentle stirring with a wide pipet tip or gentle finger-tapping. Let the precipitated antibody rehydrate for 1 hour at 4–25°C prior to use. Small particles of precipitated antibody that fail to resuspend are normal. Vials are overfilled to compensate for any losses.
