Studies have shown that in normal epithelia, HMW Cytokeratins (CK5 and CK14) stain stratified epithelia, myoepithelial cells and basal cells in the prostate gland and bronchi.15 p63 is detected in prostate basal cells in normal prostate; however, it is negative in malignant tumors of the prostate gland. Thus, p63 is useful as a differential marker […]

Hairy Cell Leukemia is a rare hematological malignancy in which B-cell lymphocytes are produced in excessive quantities. Hairy Cell Leukemia is characterized by small lymphocytes bearing fine hair-like cytoplasmic projections with infiltration of reticuloendothelial organs such as lymphoid organs and bone marrow.15,16 This mouse monoclonal antibody, also referred to as DBA.44, may be used in […]

Mast Cell Tryptase, also known as Tryptase, is a serine protease predominantly produced and stored in mast cells. It has been studied for its involvement in biological processes such as tissue remodeling and angiogenesis.15,16 According to published literature, mast cells expressing Tryptase have been observed in a variety of human tissues, including those from hematologic […]
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
Breast Cocktail (CK HMW/p63 + CK7/8/18) is comprised of mouse monoclonal anti-CK HMW and anti-p63 antibodies as well as rabbit monoclonal anti-CK7 and mouse monoclonal anti-CK8/18 antibodies. CK HMW (high molecular weight cytokeratin) is expressed in the cytoplasm of basal cells and myoepithelium of breast tissue (1-4). p63 is a transcription factor present in the […]
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 […]
The Ki-67 nuclear antigen is associated with cell proliferation and found throughout the cell cycle; though not in G0 phase (1,2). The assessment of Ki-67 proliferation in breast cancers has shown the Ki-67 labelling index is an important predictor of survival (3). Cytokeratin (CK) 7 is expressed in epithelial cells of the ovary, lung and […]
Clones EP17 and EP30 recognize cytokeratins (CK) 8 and 18, both of which are low molecular weight intermediate filament proteins (52.5 kDa and 45 kDa respectively). In normal tissues, CK8/18 recognizes all simple and glandular epithelium (1). In neoplastic tissues, CK8/18 may prove useful for the identification of most adenocarcinomas and some squamous cell carcinomas. […]
High molecular weight cytokeratins are expressed in a variety of normal and neoplastic epithelial tissues.15 p63, a homolog of the tumor suppressor p53, has been identified in proliferating basal cells in the epithelial layers of a variety of tissues, including epidermis, cervix, urothelium and prostate.16 αMethylacyl coenzyme A racemase (AMACR), also known as P504S, is […]
High molecular weight cytokeratins are expressed in a variety of normal and neoplastic epithelial tissues (1). In prostate, CK HMW [34βE12] has been shown to be a useful marker of basal cells of normal glands and prostatic intraepithelial neoplasia (PIN), a precursor lesion to prostatic adenocarcinoma; whereas invasive prostatic adenocarcinoma typically lacks a basal cell […]
