Product Information

Product Usage Information

Application Dilution
Western Blotting 1:1000

Storage

Supplied in 10 mM sodium HEPES (pH 7.5), 150 mM NaCl, 100 µg/mL BSA, 50% glycerol, and less than 0.02% sodium azide. Store at –20°C. Do not aliquot the antibody.

Specificity / Sensitivity

APOBEC3A (E6K2O) Rabbit mAb recognizes endogenous levels of total APOBEC3A protein. This antibody does not cross-react with APOBEC3B or APOBEC3G proteins. Based on the sequence of the immunogenic peptide, this antibody is not expected to detect isoform 2 of APOBEC3A.

Species Reactivity:

Human

Source / Purification

Monoclonal antibody is produced by immunizing animals with a synthetic peptide corresponding to residues surrounding Pro9 of human APOBEC3A protein.

Background

Members of the APOBEC3 subfamily of cytosine deaminases (APOBEC3A, APOBEC3B, APOBEC3C, APOBEC3D, APOBEC3F, APOBEC3G, and APOBEC3H) function in innate immunity by preventing viral DNA replication, including that of HIV-1 (1-2). APOBEC3A expression is upregulated in several human cancers, and is a major source of mutation in breast cancer (3). APOBEC3A contributes to chromosomal instability and disease progression in pancreatic cancer (4), and upregulates PD-L1 expression in cancer cells (5).

Species Reactivity

Species reactivity is determined by testing in at least one approved application (e.g., western blot).

Western Blot Buffer

IMPORTANT: For western blots, incubate membrane with diluted primary antibody in 5% w/v BSA, 1X TBS, 0.1% Tween® 20 at 4°C with gentle shaking, overnight.
