MART-1 recognizes a protein of 18 kDa, identified at MART-1 (Melanoma Antigen Recognized by T cells 1). MART-1 is a useful addition to melanoma panels as it is specific for melanocytic lesions (1- 3). Studies have shown that MART-1 is more sensitive than HMB45 when labeling metastatic melanomas (3). Tyrosinase is a key enzyme involved […]
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 […]
MART-1 recognizes a protein of 18 kDa, identified at MART-1 (Melanoma Antigen Recognized by T cells) (1). MART-1 is a useful addition to melanoma panels as it is apparently specific for melanocytic lesions (1,2). Studies have shown that MART-1 is more sensitive than HMB45 when labeling metastatic melanomas (3). This MART-1 cocktail does not stain […]
CDX2 is a homeobox gene that encodes an intestine-specific transcription factor and is expressed in the nuclei of epithelial cells of the intestine, from duodenum to rectum. The CDX2 protein is expressed in primary and metastatic colorectal carcinomas (1,2). It has also been identified in primary ovarian mucinous tumors and metastatic mucinous carcinomas involving the […]
The prostein gene encodes a 553-amino acid type IIIa plasma membrane protein with a cleavable signal peptide and 11 transmembrane-spanning regions (1). IHC analysis has demonstrated that the Prostein antibody (also known as P501S) was expressed in the normal prostate tissue and the vast majority of malignant prostatic tissues, regardless of grade and metastatic status […]
MART-1 recognizes an 18 kDa protein (Melanoma Antigen Recognized by T cells 1) and is specific for melanocytic lesions, making it a valuable component of melanoma panels.15-17 MART-1 has been shown to be more sensitive than HMB45 for labeling metastatic melanomas. Tyrosinase, a key enzyme in early melanin biosynthesis, is more sensitive than HMB45 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. […]
The Biocare CDX2 antibody detects CDX2, a homeobox gene–encoded, intestine-specific transcription factor.15 CDX2 is useful in establishing the gastrointestinal origin of metastatic adenocarcinomas and carcinoids and can aid in distinguishing metastatic colorectal adenocarcinoma from tumors of unknown origin.15-21 Studies have shown that CDX2 to be more specific and sensitive than villin or CK20.15,19,20 CDX2 expression […]
Thyroid transcription factor-1 (TTF-1) is a member of the NKX2 family of homeodomain transcription factors. Studies have shown that TTF-1 is expressed in epithelial cells of the thyroid gland and lung. TTF-1 has been shown to be a sensitive (62-80%) and specific marker (89-95%) in the majority of primary lung adenocarcinomas (ADC) (1-7). When combined […]
Concord, CA, August 27, 2015 – Biocare Medical is proud to announce the availability of CK HMW + p63 + AMACR (RM) as an IVD double-stain for Multiplex IHC™. This patented antibody cocktail may be useful in the evaluation of normal prostate glands, prostatic intraepithelial neoplasia (PIN) and prostatic adenocarcinoma (1,2). Previously, this product was […]
