Simple Western™ analysis of lysates (1 mg/mL) from 22Rv-1 cells using Androgen Receptor (AR-V7 Specific) (E3O8L) Rabbit mAb #19672. The virtual lane view (left) shows a single target band (as indicated) at 1:50 and 1:250 dilutions of primary antibody. The corresponding electropherogram view (right) plots chemiluminescence by molecular weight along the capillary at 1:50 (blue line) and 1:250 (green line) dilutions of primary antibody. This experiment was performed under reducing conditions on the Jess™ Simple Western instrument from ProteinSimple, a BioTechne brand, using the 12-230 kDa separation module.

Western blot analysis of extracts from various cell lines using Androgen Receptor (AR-V7 Specific) (E3O8L) Rabbit mAb (upper) and Β-Actin (D6A8) Rabbit mAb #8457 (lower). Signal corresponding to the androgen receptor V7 isoform is detected in 22Rv1 and VCAP cells (AR-V7-positive), but is not detected in LNCaP and DU 145 cells (AR-V7-negative), confirming specificity of the antibody.
Chromatin immunoprecipitations were performed with cross-linked chromatin from 22-RV-1 cells, treated with 10 nM DHT for 4hr and either Androgen Receptor (AR-V7 Specific) (E3O8L) 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 SPINK5 upstream primers, ABCB5 upstream 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.

CUT&RUN was performed with LNCaP cells grown in phenol red free medium and 5% charcoal stripped FBS for 3 d then treated with dihydrotestosterone (DHT, 10 nM) for 4 hours and Androgen Receptor (D6F11) XP® Rabbit mAb, using CUT&RUN Assay Kit #86652. DNA Libraries were prepared using DNA Library Prep Kit for Illumina® (ChIP-seq, CUT&RUN) #56795. The figure shows binding across KLK2, a known target gene of Androgen Receptor (see additional figure containing CUT&RUN-qPCR data).

After the primary antibody is bound to the target protein, a complex with HRP-linked secondary antibody is formed. The LumiGLO® is added and emits light during enzyme catalyzed decomposition.

Product Description

The Androgen Receptor Antibody Sampler Kit provides an economical means of detecting full-length Androgen Receptor and AR-V7 isoforms. The kit includes enough antibody to perform two western blot experiments with each primary antibody.

Specificity / Sensitivity

Each antibody in the Androgen Receptor Antibody Sampler kit detects endogenous levels of its target protein. Androgen Receptor (D6F11) XP® Rabbit mAb detects both full-length AR and the AR-V7 isoform. Androgen Receptor (E3S4N) Rabbit mAb (Carboxy-terminal Antigen) detects only full-length AR. Androgen Receptor (AR-V7 Specific) (E3O8L) Rabbit mAb only detects the AR-V7 isoform.

Source / Purification

Monoclonal antibodies are produced by immunizing rabbits with recombinant protein corresponding to residues near the amino terminal region of human androgen receptor protein, and with synthetic peptides corresponding to residues surrounding Val662 of human androgen receptor protein and Leu639 of human androgen receptor (V7 isoform) protein.

Background

Androgen receptor (AR), a zinc finger transcription factor belonging to the nuclear receptor superfamily, is activated by phosphorylation and dimerization upon ligand binding (1). This promotes nuclear localization and binding of AR to androgen response elements in androgen target genes. Research studies have shown that AR plays a crucial role in several stages of male development and the progression of prostate cancer (2,3).

The AR3 or AR-V7 isoform, which lacks the typical ligand binding domain, is created through the alternative splicing of cryptic exons (4-5). AR-V7 is frequently expressed in castration-resistant prostate cancer (CRPC) and while dependent on the activity of the full-length androgen receptor (AR-FL), AR-V7 can activate a completely distinct transcriptional program (6-8). While enzalutamide and abiraterone have been beneficial in treating CRPC through the ligand binding domain of AR-FL, resistance in patients has been shown to be associated with AR-V7 detection in circulating tumor cells (9-12). Studies probing into mechanisms of overcoming this resistance are currently being explored and may help in stratifying patient populations for more personalized therapies (13-15).
