Cytokeratin 5 [EP24]
Description Keratins are cytoplasmic intermediate filament proteins expressed by epithelial cells. The mitotically active basal layers of most stratified squamous epithelia express 10% to 30% of their total protein as keratin. The two keratins specifically expressed in these cells are the type II keratin CK5 and its corresponding partner, type I keratin CK14, both of which are essential for the formation of 8-nm filaments. CK5 and calretinin have been useful in different studies as immunohistochemical markers suggestive of mesothelioma, and their expression is analyzed for the histological differential diagnosis with adenocarcinomas, especially when confronting with metastatic tumors of unknown origin. CK5 labels myoepithelial cells of breast and prostate basal cells. A cocktail of CK5, CK14 and p63, has been used as sensitive and specific basal cell marker of basal-like phenotype of breast carcinoma and to differentiate normal and prostate cancer.

Desmin [MD97R]
Description Desmin is a characteristic intermediate filament of all three types of muscle cells (skeletal, cardiac, and smooth muscle) and neoplasms associated with them. In general, desmin is a specific marker for myogenic differentiation among soft tissue tumors. It is seen in the majority of rhadbomyomas,leiomyomas, rhadbomyosarcoma, and leiomyosarcomas. Desmin is also seen in myofibroblasts. Myoepithelial cells typically lack desmin. The antibody labels smooth and striated muscle cells as well as mesothelial cells. It allows the subtyping of many undifferentiated and pleomorphic tumors through intermediate filament analysis. With selected panels of antibodies, it is a useful tool to separate the different pleomorphic spindle cell tumors and round cell tumors in soft tissues and skin. The antibody labels strongly reactive mesothelial cells, but not malignant mesothelioma and adenocarcinoma.

EGFR (E746-A750del Specific) [SP111]
Description Two types of mutations account for approximately 90% of mutated cases: a specific point mutation, L858R, which occurs in exon 21 and short in-frame deletions in exon 19. A common lesion in exon 19 is the deletion of E746-A750, although other variants occur. IHC-based EGFR E746-A750del specific antibody is designed to detect deletion of E746-A750 in exon 19. Deletion in exon 19 is associated with response of non-small cell lung carcinoma (NSCLC) to gefitinib or erlotinib monotherapy.

EGFR [MD115R]
Description Epidermal growth factor receptor (EGFR) is a 170 kDa transmembrane glycoprotein receptor tyrosine kinase that, activated by epidermal growth factor (EGF), affects cell growth and differentiation. Binding of EGF or TGF alpha to EGFR activates tyrosine kinase activity of the receptor. Phosphorylation of Tyr 992, Tyr 1068 and Tyr 1086 is required for conformational change in the C-terminal of EGFR. Autophosphorylation of Tyr 992 creates a binding site for the phospholipase C-gamma (PLC-gamma) SH2 domain, inducing downstream signaling. In breast cancer, EGFR is predorminately expressed in basal cell-like carcinoma, it has been recommendated for identification of basal-like breast carcinoma along with Cytokeratin 5/6.

EGFRvIII [MD99R]
Description Epidermal growth factor receptor (EGFR) is a receptor for EGF and for various members of the EGF family such as TGF-alpha, amphiregulin, betacellulin, heparin-binding EGF-like growth factor, GP30 and vaccinia virus growth factor. EGFR is involved in the control of cell growth and differentation. Binding of EGF to the receptor leads to dimerization, internalization of the EGF-receptor complex, induction of the tyrosine kinase activity, stimulation of cell DNA synthesis and cell proliferation. EGFRvIII has an 801-bp in-frame deletion resulting in a shorter extracellular domain (aa 6-273 are deleted) with generation of a glycine residue at the fusion point. EGFRvIII is tumor specific and is not expressed in normal human tissues. Defects in EGFR are associated with lung cancer.

ER [EP1]
Description Estrogen Receptor Alpha (ER or ER Alpha) is a nuclear protein and member of the steroid hormone receptor family. ER alpha possesses both DNA binding and ligand binding domains, and exerts a significant role in activating the transcription of certain genes. Ligand-dependent dimerization and phosphorylation both function to regulate the transcriptional activation of ER alpha.
