CK5 and CK14 are high molecular weight keratins expressed in the cytoplasm of basal cells and myoepithelium of breast tissue.15 p63 is a transcription factor present in the nuclei of myoepithelial cells.16 P504S is a peroxisomal and mitochondrial enzyme that plays a role in bile acid synthesis and β-oxidation of branched chain fatty acids.17
CK5 and CK14 are high molecular weight cytokeratins expressed in a variety of normal and neoplastic epithelial tissues (1). In prostate tissue, mRNA for CK5 and CK14 has been detected in the basal cells of normal glands and prostatic intraepithelial neoplasia (PIN), a precursor lesion to prostatic adenocarcinoma; however, expression of CK5 or CK14 was […]
Concord, CA, July 17, 2014 – Biocare Medical is proud to announce that the United States Patent and Trademark Office has issued US Patent 8,603,765 to Biocare Medical for its PIN-4™ (CK5/14 + P63 + P504S) Multiplex immunohistochemistry (IHC) technology. The PIN-4 antibody cocktail of P504S + p63 + High Molecular Weight Cytokeratin permits the […]
CK5 and CK14 are high molecular weight cytokeratins expressed in a variety of normal and neoplastic epithelial tissues. p63, a homolog of the tumor suppressor p53, was detected in nuclei of the basal epithelium in normal prostate glands; however, it was not expressed in malignant tumors of the prostate. Expression of P504S protein is found […]
The p63 + CK5 Multiplex IHC stain has been especially designed for squamous cell carcinomas, particularly those derived in lung cancer. p63, a homolog of the tumor suppressor p53, has been identified in basal cells in the epithelial layers of a variety of tissues, including epidermis, cervix, urothelium, breast and prostate.15 CK5 is a 58 […]
CK5 and CK14 are high molecular weight keratins expressed in the cytoplasm of basal cells and myoepithelium of breast tissue.15 p63 is a transcription factor present in the nuclei of myoepithelial cells.16 P504S is a peroxisomal and mitochondrial enzyme that plays a role in bile acid synthesis and β-oxidation of branched chain fatty acids.17
IHC markers CK5, CK14, p63, CK7 and CK18 complement morphological evaluation of breast lesions, due to the differential expression of the luminal (CK7/18) vs. basal and myoepithelial markers (CK5/14, p63). Usual ductal hyperplasia is associated with positive basal cells markers, intermixed with positive luminal cells. Most atypical ductal hyperplasia and low grade ductal carcinoma in […]
Cytokeratin 5 is a 58 kDa protein that is closely related to CK6. They share similar tissue distribution and are found in various proportions in many nonkeratinizing stratified squamous epithelia such as tongue mucosa, basal epithelia hair follicles, trachea, as well as basal cells in prostate glands and in mammary glands. CK5 is also expressed […]
MACH Infinity 2.5 is designed using a one-step method for detecting mouse and rabbit primary antibodies to form an antibody-enzyme complex. This complex is then visualized using an appropriate substrate/chromogen. In the one-step method a secondary antibody directly linked to the micro-polymer is applied.

CD54, also known as Intercellular adhesion molecule 1 (ICAM1) is a 90 kDa glycosylated transmembrane protein of the immunoglobulin superfamily. CD54 plays an important role in immunological synapse formation, T-cell activation, leukocyte migration, and numerous cellular immune responses.15 While some studies have shown that CD54 promotes tumor metastasis by regulating various signaling pathways in some […]
