Prostate cancer IHC panel

Prostate cancer diagnostic solutions

Prostate cancer is a major public health concern. Globally, prostate cancer is the fourth most common cancer (all genders) and the second most common cancer in men.^1,2 In the United States, approximately one man in nine will be diagnosed with prostate cancer in his lifetime.³ Approximately 70% of prostate cancer cases are low risk, yet up to 90% are treated aggressively.⁴

We offer a wide menu of immunohistochemistry (IHC) assays. Our portfolio of products delivers the high sensitivity and specificity you need.

Our antibodies are ready-to-use on the fully automated VENTANA BenchMark IHC/ISH staining platforms, reducing the time-to-result and resources required with manual or semi-automated solutions. We have a robust assay development program focusing on immunohistochemical staining, clinical reagents, cancer diagnostic assays and much more.

Featured assays

immunohistochemical staining with Basal Cell Cocktail 34ßE12 + p63

VENTANA Basal Cell Cocktail (34ßE12+p63)

VENTANA Basal Cell Cocktail (34βE12+p63) is an antibody cocktail of p63 (4A4) and keratin (34βE12). It may be used to aid in the differentiation of benign lesions with basal cells from malignant prostate lesions lacking basal cells. Identification of basal cells has been an immunohistochemical cornerstone for decades in diagnosis of prostate adenocarcinoma.^5,6

p504s (SP116) Rabbit Monoclonal Primary Antibody

p504s (SP116) Rabbit Monoclonal Primary Antibody is directed against the p504s enzyme (also known as alpha-Methylacyl Coenzyme A racemase or AMACR). p504s is found to be overexpressed in human prostatic carcinoma, and exhibits a granular, cytoplasmic staining pattern in malignant glands and cells.⁷

Publications demonstrate the utility of p504s as an aid to the pathologist in recognizing small foci prostatic carcinoma when used to complement an absence of basal cell staining.⁸ This can be achieved in a dual stain with the Basal Cell Cocktail (34βE12 + p63) to optimize the use of limited available tissue on small focal cancer biopsies.⁹

NKX3.1 (EP356) Rabbit Monoclonal Primary Antibody

NKX3.1 (EP356) Rabbit Monoclonal Primary Antibody is a sensitive and specific antibody for the detection of NKX3.1 protein. Publications demonstrate that the reliable detection of NKX3.1 may have utility in a number of clinical applications in prostatic carcinoma and breast carcinomas.¹⁰

Prostatic carcinoma: There is a high frequency of NKX3.1 expression in prostatic adenocarcinoma with greater than 98% sensitivity and specificity.^11,12
Gurel et al., demonstrated that nearly all cases of metastatic prostate adenocarcinoma were stained by NKX3.1.¹²
Gurel and Chuang showed that nearly all cases of urothelial carcinoma were negative for NKX3.1.^12,13
NKX3.1-positive prostate carcinoma cells exhibit nuclear staining.¹²

Clinical reagents and assays include the p63 (4A4) Mouse Monoclonal Primary Antibody

VENTANA anti-p63 (4A4) Mouse Monoclonal Primary Antibody

The VENTANA anti-p63 (4A4) antibody is directed against the p63 molecule, which is highly expressed in the nuclei of human prostatic basal cells and urothelial tissues. This powerful tool can aid the pathologist in the differential diagnosis of prostate cancer in conjunction with morphological findings. Delivering consistently strong nuclear staining, this antibody may be used to aid in the differentiation of benign and malignant prostatic lesions.^14,15

anti-ERG (EPR3864) Rabbit Monoclonal Primary Antibody

The ERG (EPR3864) Rabbit Monoclonal Primary Antibody is capable of detecting: Truncated ERG resulting from TMPRSS2:ERG (or other ERG gene fusions) and wildtype ERG (most notably expressed in vessel endothelium).¹⁶ This antibody exhibits a nuclear staining pattern and may be used to aid in the identification of prostate adenocarcinomas through the detection of truncated ERG.^17,18TMPRSS2-ERG gene fusions occur in 50% of prostate cancers and result in the overexpression of a chimeric fusion transcript that encodes a truncated ERG product. Anti-ERG (EPR3864) Rabbit Monoclonal Primary Antibody may facilitate functional studies of ERG gene fusions and subtyping of prostate cancer.¹⁹
