Each lot of this antibody is quality control tested by Western blotting. For Western blotting applications, a concentration of 1 ?g/mL?is recommended.?For ChIP applications, the suggested dilution is is 1:100-1:2000 by volume.?It is recommended that the reagent be titrated for optimal performance for each application.

7A6 antibody detects endogenous human NFATC1 in Western blot.?There are 10 isoforms with a predicted MW of 39kD, 74kD, 76kD, 77kD (3), 88kD (2), 100kD, 101kD.?With this antibody, observed MW bands range from 70 - 120 kD.?The optimal concentration should be determined by titration for each individual assay of interest.

Clone 7A6 Intracellular Staining Procedure:

1. Prepare the fix/perm solution, consisting of 1% paraformaldehyde in 70% ethanol. Chill for at least one hour at -20°C.
2. Suspend cells in cell staining buffer and perform surface stain if necessary.
3. Centrifuge for 5 minutes at 1500 RPM and discard supernatant.
4. Resuspend cells in 500 ?L of fix/perm solution for up to 2 x 10^6 cells and gently vortex.
5. Incubate cells on ice for 30-60 minutes in the dark.
6. Add 2 mL PBS and centrifuge cells for 1500 RPM for 5 minutes.
7. Wash cells 1X with 2 mL cell staining buffer, centrifuge at 1500 RPM for 5 minutes, discard supernatant.
8. Adjust cell concentration to about 1 x 10^7 cells/mL, add 100 ?L (~ 1 x 10^6 cells) to a FACS tube that already contains the staining antibody and mix gently.
9. Incubate 15 minutes at room temperature.
10. Wash 2X with cell staining buffer as in step 6.
11. Resuspend cells in cell staining buffer and analyze.
