Information d'application

Indications d'application: Recommended Protocol for Bioimaging:
1. Seed the cells in appropriate culture medium at an appropriate cell density in an 96-well Imaging Plate , and culture overnight to 48 hours.
2. Remove the culture medium from the wells, and wash (one to two times) with 100 myl of 1× PBS.
3. Fix the cells by adding 100 µl of fresh 3.7% Formaldehyde in PBS or fixation buffer to each well and incubating for 10 minutes at room temperature (RT).
4. Remove the fixative from the wells, and wash the wells (one to two times) with 100 myl of 1× PBS.
5. Permeabilize the cells using either cold methanol (a), Triton™ X-100 (b), or Saponin (c): a. Add 100 µl of -20°C 90% methanol to each well and incubate for 5 minutes at RT. b. Add 100 µl of 0.1% Triton™ X-100 to each well and incubate for 5 minutes at RT. c. Add 100 µl of 1× Perm/Wash buffer to each well and incubate for 15 to 30 minutes at RT. Continue to use 1× Perm/Wash buffer for all subsequent wash and dilutions steps.
6. Remove the permeabilization buffer from the wells, and wash one to two times with 100 myl of appropriate buffer (either 1× PBS or 1× Perm/Wash buffer, see step 5.c.).
7. Optional blocking step: Remove the wash buffers, and block the cells by adding 100 µl of blocking buffer or 3% FBS in appropriate dilution buffer to each well and incubating for 15 to 30 minutes at RT.
8. Dilute the antibody to its optimal working concentration in appropriate dilution buffer. Titrate purified (unconjugated) antibodies and second-step reagents to determine the optimal concentration. If using a Bioimaging Certified antibody conjugate, dilute it 1:10.
9. Add 50 µl of diluted antibody per well and incubate for 60 minutes at RT. Incubate in the dark if using fluorescently labeled antibodies.
10. Remove the antibody, and wash the wells three times with 100 myl of wash buffer. An optional detergent wash (100 myl of 0.05% Tween in 1× PBS) can be included prior to the regular wash steps.
11. If the antibody being used is fluorescently labeled, then move to step 12. Otherwise, if using a purified unlabeled antibody, repeat steps 8 to 10 with a fluorescently labeled second-step reagent to detect the purified antibody.
12. After the final wash, counter-stain the nuclei by adding 100 ml of a 2 mg/ml solution of Hoechst 33342 in 1× PBS to each well at least 15 minutes before imaging.
13. View and analyze the cells on an appropriate imaging instrument.

Recommended Assay Procedure for Tissue Sections:
1. Harvest target organs or tissues and flush with PBS.
2. Place the tissues in cassettes and fix with 10% neutral buffered formalin for 16 hrs.
3. Remove the fixative and proceed with processing and embedding in paraffin using standard protocols.
4. Cut paraffin-embedded tissue sections (5 µm) using a microtome, adhere sections onto colorfrost slides, and allow them to air dry.
5. Deparaffinize and re-hydrate the sections.
6. Treat with Retrievagen A by heating the slides in a pressure cooker at 121°C for 15 minutes at 17 psi.
7. Allow the slides to cool to room temperature in the Retrievagen A, rinse the slides with tap water, and store in PBS prior to antibody staining.
8. Sections can be simultaneously stained with a cocktail of multiple antibodies at pre-optimized concentration, for 2 hours at room temperature.
9. Wash the sections in 1× PBS.
10. If required label cellular DNA with 2 µg/ml Hoechst 33342 for 30 minutes, and wash with 1× PBS.
11. Place cover slips on the sections using Aqua-Mount.
12. View and analyze the samples on an appropriate imaging instrument.

Sujet: 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 (observed MW) 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, disruption of the GATA4 gene leads to defects in heart tube formation, while mutations of GATA4 are associated with atrial septal defects in humans. In the adult heart, GATA4 regulates differentiated gene expression. The roles of GATA4 in endocrine and reproductive functions were recently reviewed.
