Prostate cancer IHC portfolio

Prostate IHC assay
Prostate cancer diagnostic solutions

Globally, prostate cancer is the fourth most common cancer overall and the second most common cancer in men.1 In England, prostate cancer continues to be the most common cancer diagnosed in males in 2017 with 41,201 cases diagnosed, which accounted for one in four (26.3%) male cancer diagnoses.2

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 anti-p63 (4A4) and anti-keratin (34βE12). It may be used to detect basal cells to aid in the differentiation of benign and malignant prostate lesions. For more than 15 years, basal cells have been the immunohistochemical cornerstone in the diagnosis of prostate cancer.3,4

Immunohistochemical staining of p504s (SP116) Rabbit Monoclonal Primary Antibody
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.14

Publications demonstrate the utility of p504s as an aid to the pathologist in recognising small foci prostatic carcinoma when used to complement an absence of basal cell staining.15 This can be achieved in a dual stain with the Basal Cell Cocktail (34βE12 + p63) to optimise the use of limited available tissue on small focal cancer biopsies.16

ihc detection: NKX3.1 (EP356) Rabbit Monoclonal Primary Antibody
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.8

  • Prostatic carcinoma: There is a high frequency of NKX3.1 expression in prostatic adenocarcinoma with greater than 98% sensitivity and specificity.9,10
  • Gurel et al., demonstrated that nearly all cases of metastatic prostate adenocarcinoma were stained by NKX3.1.10
  • Gurel and Chuang showed that nearly all cases of urothelial carcinoma were negative for NKX3.1.10,11
  • NKX3.1-positive prostate carcinoma cells exhibit nuclear staining.10
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.17-19

Clinical reagents and assays include the p63 (4A4) Mouse Monoclonal Primary Antibody
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) wildtype ERG (most notably expressed in vessel endothelium).
