p40 recognizes the shortest variant of human p53 and may be a valuable marker in cases where p63 has traditionally been used. At present, p63 is the most frequently used marker for lung squamous cell carcinoma (SqCC).15 However, p40 may prove to be an important antibody in the differential diagnosis of lung adenocarcinoma vs. lung […]
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 […]
Desmoglein 3 (DSG3) is a calcium-binding transmembrane glycoprotein component of desmosomes in vertebrate epithelial cells. Currently, three desmoglein subfamily members have been identified and all are members of the cadherin cell adhesion molecule superfamily (1,2). Desmogleins exhibit membranous expression and connect with cytokeratins through desmoplakins and plakoglobin. DSG3 is particularly important in the cellular adhesion […]
The mouse monoclonal antibody p40 [BC28] recognizes an epitope unique to the p40 protein and may have applications in cases where p63 has traditionally been used. To date, p63 [4A4] has been a frequently used marker of basal epithelium in normal prostate, with expression not typically observed in prostatic adenocarcinoma. A study has shown p40 […]

Biocare Medical takes great pride in our promise of “Fighting Cancer, One Slide at a Time.” Our focus in the fight against cancer is realized through our high-quality immunohistochemistry (IHC) and in situ hybridization (ISH) reagents and instrumentation. Specifically, our sensitive and specific antibodies, molecular probes, and detection chemistries support early and accurate classification of […]
Early on, Biocare recognized the market need for evaluating morphologically distinct markers to aid in solving complex clinical problems and simplifying interpretation, all while conserving precious patient tissue. The most glaring clinical need was determined to be the ability to differentiate between prostatic intraepithelial neoplasia (PIN) and carcinoma of the prostate. There also needed to […]
Distinguishing between invasive urothelial carcinoma (UC) from other genitourinary malignancies, such as prostatic and renal carcinomas, can be difficult. Several new markers such as GATA binding protein 3 (GATA-3), S100P, and uroplakin III have been developed for this differentiation (1-7). More recently uroplakin II has been introduced (1-7). GATA-3 is a transcription factor and belongs […]
