Application Notes

Validated Applications:
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.

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.

Positive Control

Active Motif's Schneider's Drosophila L2 nuclear extract (Catalog No. 36087) can be used as a positive control for Acf1 antibody.

Compatible Secondary Antibodies

Active Motif has developed a variety of high-quality secondary antibodies for most applications, with anti-rabbit and anti-mouse conjugates to a broad line of high-quality fluorescent molecules, as well as horse radish peroxidase (HRP). Visit our Secondary Antibody Conjugates page to find the perfect secondaries for immunofluorescence experiments with Acf1 antibody (pAb).


Some products may be shipped at room temperature. This will not affect their stability or performance. Upon receipt, unconjugated antibodies may be stored at -20°C for up to 2 years. Fluorophore- & enzyme-conjugated antibodies should be stored at 4°C. Fluorophore-conjugated antibodies should be protected from light. Keep reagents on ice when not in storage; to avoid repeated freeze/thaw cycles, we recommend aliquoting items that will be stored frozen into single-use fractions prior to freezing.
