Product Information

Product Usage Information

For optimal ChIP results, use 10 μl of antibody and 10 μg of chromatin (approximately 4 × 10^6 cells) per IP. This antibody has been validated using SimpleChIP® Enzymatic Chromatin IP Kits.

Application Dilution
Western Blotting 1:1000
Immunoprecipitation 1:50
Chromatin IP 1:50

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

HOXD9 (E3F2T) Rabbit mAb recognizes endogenous levels of total HOXD9 protein. This antibody does not cross-react with HOXA9, HOXB9 or HOXC9 proteins. This antibody also weakly recognizes non-specific bands of unknown origin at 55 and 70 kDa in some cell lines.

Species Reactivity:

Human, Monkey

Source / Purification

Monoclonal antibody is produced by immunizing animals with a synthetic peptide corresponding to residues surrounding Gly159 of human HOXD9 protein.

Background

Homeobox protein Hox-D9 (HOXD9) is a sequence-specific transcription factor that is part of a developmental regulatory program that provides cells with specific positional identities on the anterior-posterior axis. HOXD9 is developmentally expressed in structures of either mesodermal or neuro-ectodermal origin, such as developing limbs, gonads, and the central nervous system (1-6). HOXD9 plays a critical role in regulation of limb development, neuronal development, and development of mammary glands and gonads in many organisms (1-6). The HOXD9 gene promoter is found to be hypermethylated and silenced in multiple types of cancer, including breast cancer, melanoma brain metastases, and cholangiocarcinomas (7-9). In addition, HOXD9 expression is increased in other types of cancer, including human glioblastomas and astrocytomas, where expression appears to drive growth of the tumors (10).

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 nonfat dry milk, 1X TBS, 0.1% Tween® 20 at 4°C with gentle shaking, overnight.

Western blot analysis of extracts from various cell lines using HOXD9 (E3F2T) Rabbit mAb.
Western Blotting Image 2: HOXD9 (E3F2T) Rabbit mAb Expand Image
Western blot analysis of extracts from 293T cells, mock transfected (-) or transfected with constructs expressing Myc/DDK-tagged full-length human HOXA9 protein (hHOXA9-Myc/DDK; +), Myc/DDK-tagged full-length human HOXC9 protein (hHOXC9-Myc/DDK; +), and Myc/DDK-tagged full-length human HOXD9 protein (hHOXD9-Myc/DDK; +), using HOXD9 (E3F2T) Rabbit mAb (upper) or DYKDDDDK Tag (D6W5B) Rabbit mAb #14793 (lower).
Immunoprecipitation Image 1: HOXD9 (E3F2T) Rabbit mAb Expand Image
Immunoprecipitation of HOXD9 protein from A-673 cell extracts. Lane 1 is 10% input, lane 2 is Rabbit (DA1E) mAb IgG XP® Isotype Control #3900, and lane 3 is HOXD9 (E3F2T) Rabbit mAb. Western blot analysis was performed using HOXD9 (E3F2T) Rabbit mAb. Mouse Anti-Rabbit IgG (Light-Chain Specific) (D4W3E) mAb (HRP Conjugate) #93702 was used as the secondary antibody.
Chromatin Immunoprecipitation Image 1: HOXD9 (E3F2T) Rabbit mAb Expand Image
Chromatin immunoprecipitations were performed with cross-linked chromatin from untreated A-673 cells and either HOXD9 (E3F2T) Rabbit mAb or Normal Rabbit IgG #2729 using SimpleChIP® Plus Enzymatic Chromatin IP Kit (Magnetic Beads) #9005. The enriched DNA was quantified by real-time PCR using SimpleChIP® Human KLF3 Intron 1 Primers #23707, human EHD3 downstream primers, and SimpleChIP® Human α Satellite Repeat Primers #4486. The amount of immunoprecipitated DNA in each sample is represented as signal relative to the total amount of input chromatin, which is equivalent to one.
