Anti-Ptx3/PITX3 Antibody

Pitx3, the third member of the Pitx family, is expressed in the eyes and in only one population of neurons, the dopaminergic neurons of the midbrain. In human, mutations of the Pitx3 gene have been associated with a familial form of cataracts, which is consistent with one of the developmental roles of this gene. Pitx3 expression in the midbrain starts just before terminal differentiation of dopaminergic neurons. This temporal expression is consistent with a role of Pitx3 in the differentiation and/or maintenance of these neurons.

Recognizes Ptx3 / PITX3 (Bicoid, Bcd family), a homeodomain transcription factor.

Precipitated antibody in a solution of 50% saturated ammonium sulfate and PBS containing no preservatives.

Maintain unopened vial 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 affect 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 a suitable biological buffer such as PBS or TBS (pH 7.3-7.5) to a final concentration of 1.0 mg/mL. For example, to achieve a 1.0 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.

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 long-term storage at -70°C, 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.
