Application Notes

Applications Validated by Active Motif:
ICC/IF: 1:500 - 1:1,000 dilution
WB: 1:500 - 1:1,000 dilution

The addition of 0.05% Tween 20 in the blocking buffer and primary antibody incubation buffer is recommended to aid in detection by Western blot. Individual optimization may be required.


This Acf1 antibody was raised against recombinant C-terminal fragment of Acf1 from Drosophila melanogaster.


PBS containing 0.1% sodium azide, 0.2 mg/ml BSA and 35% glycerol. Sodium azide is highly toxic.


Acf1 pAb tested by immunofluorescence.
Drosophila polytene chromosomes stained with Acf1 pAb (1:1,000 dilution).

Acf1 pAb tested by Western blot.
Drosophila Schneider L2 cells nuclear extract (10 µg) probed with Acf1 pAb (1:500 dilution).


Drosophila Acf1 is a component of ACF, the ATP-utilizing chromatin assembly and remodeling factor protein complex. ACF catalyzes the ATP-dependent assembly of periodic nucleosome arrays in vitro. The catalytic subunit of ACF is the ISWI ATP-dependant chromatin remodeling protein. ACF is related to CHRAC (Chromatin Accessibility Complex), which also contains Acf1 and ISWI. ACF is involved in the establishment and possibly maintenance of silenced heterochromatic domains in the genome, both at pericentric heterochromatin and at genes repressed by the Polycomb complex.
