S 100 protein tumor marker

S-100 protein was identified in virtually all nerve sheath tumours such as schwannomas, neurofibromas, myxoid sheath nerve tumour and also in some tumours of controversial histogenesis such as granular cell tumours. The great majority of carcinomas did not express S-100, with only two cases of breast carcinoma displaying focal S-100 staining S-100 protein (S-100B) is the most widely used marker for peripheral nerve sheath tumors. Although S-100 protein is positive in all benign Schwann cell tumors, this marker shows relatively low sensitivity for MPNST (at most, around 50%)

Vizsgálat - S100 protein. A vizsgálat a szérumban lévő S100 (S100 A1B és S100 BB) mennyiségi meghatározására való. Az S100A1-t és az S100B-t túlnyomórészt a központi idegrendszer asztrogliális sejtjei termelik, de megtalálhatók a melanóma-sejtekben és bizonyos mértékben más szövetekben is S100 is an acidic-calcium-binding protein, composed as a heterodimer of two isomeric subunits alpha and beta and was first described in cells of neuroendocrine origin. It plays an important role in various cellular processes such as cell differentiation and proliferation and interacts with the tumou S100 protein — tumor marker associated with malignant melanoma Malignant melanoma represents one of the most aggressive types of skin cancer. The tumor develops from melanocytes — cells that produce melanin (pigment). These cell produce S100 protein, which is used as a marker for malignant transformation of melanocytes A tumormarkerek olyan anyagok, amelyek a rosszindulatú daganatokkal összefüggésben keletkezhetnek. Ezek az anyagok vagy magukból a tumorsejtekből származnak, vagy a test tumorra adott reakciója során keletkeznek

Ezenkívül gyulladásos gócokat jelez még a CRP (C-reaktív protein) érték is Although S-100 protein is positive in all benign Schwann cell tumors, this marker shows relatively low sensitivity for MPNST (at most, around 50%). Because S-100 protein is also expressed in a variety of other cell types, a range of other tumors are also consistently positive; still other tumor types show variable expression of this marker.

MIN — S100 protein tumormarker

BACKGROUND: S-100 protein, commonly used in the immunohistochemical diagnosis of malignant melanoma and melanoma metastases, has recently been introduced as a tumor marker in peripheral blood. OBJECTIVE: This prospective, observational, 2-center study evaluates S-100 in peripheral blood of patients with melanoma as a marker for metastasis S-100 protein has been used as a marker of various lesions, including peripheral nerve sheath, cartilaginous and salivary gland tumors, chordomas, histiocytosis X, and melanomas, among others. The list of neoplasms that can express S-100 protein continues to expand It is helpful in separating malignant peripheral nerve sheath tumors from other similar appearing sarcomas (e.g., fibrosarcoma) S-100 protein can be found in most melanoma cells. Tissue samples may be tested for this marker to help in diagnosing melanoma metastasis. S-100 protein is present within occasional non-neural tissues and tumors. It has been identified in normal adipocytes, lipomas, and occasional liposarcomas S-100 Protein and Neuron-Specific Enolase in Cerebrospinal Fluid and Serum: Markers of Cell say and immunoassay in tumor tissue and serum from of the lung and can therefore be used as a marker for these tumors.1418 Studies on cerebrospinal fluid (CSF) concentrations of S-100 and NSE in patients with neurologic lesion

S‐100 protein, a dimer of S‐100α and S‐100β subunits (S‐100α and S‐100β), is widely distributed in human tissue, and several papers describing S‐100 protein expression in follicular cells of the thyroid have been published. in the present study, 105 cases of thyroid carcinoma (of which 96 were papillary, four follicular, two undifferentiated, and three meduilary) were analyzed immunohistochemically for the expression of S‐100 protein, S‐100α, S‐100β, and thyroglobulin. The method according to claim 9, wherein said tumor marker is one or more members selected from the group consisting of Ker, EMA, LCA, S-100, HMB-45, PLAP, Desmin, MBP, F-R:Ag, NF and CG. 14. The method according to claim 8, wherein said metal is copper, silver, aluminum or gold However, S-100 protein expression must be regarded with caution because it does not necessarily represent a marker of nerve sheath tumor as inferred by the long list of benign tumor that expresses this protein, specially intradermal nevus including nevus with neural differentiation

Cellular localization of S-100 protein now allows identification of myoepithelial cells and tumors composed of these cells. The four tumors presented in this report illustrate the diagnostic advantages afforded by S-100 protein immunocytochemistry.

S100 is a family of cytoplasmic calcium-binding proteins expressed in numerous cell lines which can be targeted by immunohistochemistry.Staining for S100 is helpful in characterizing a number of tumors, including malignant melanoma, glial tumors, neurogenic tumors (e.g. schwannomas and neurofibromas), mesenchymal tumors (e.g. chondromas, chondrosarcomas, liposarcomas, some osteogenic sarcomas.

He said in the states we really don't have a standard that is recognized as a reliable marker for disease spread tumor examined. Immunohistochemistry for S-100 was pos-itive in tissues from blocks up to 17 years old. Thus, S-100 staining was very sensitive. However, we also detected S-100 in several nonmelanoma tumor types that have been shown to be S-100 positive in other studies.4,6,9 All three schwannomas we tested were S-100 positive (Fig. 7). Th

Thank you for your inquiry. I can confirm that antibody ab7852 should recognize the protein ab54050. But ab7852 (Anti-S100 antibody [B32.1] - Astrocyte Marker) is not tested and guaranteed for WB and it is not known if it binds to denatured S100 beta protein. Therefore I cannot recommend to use ab7852 with ab54050 in WB To determine S-100 protein levels, serum samples from 20 patients with various intracranial tumors were collected before surgery, and at one day, as well as at seven days after surgery. It was hypothesised that the size of the tumor-brain contact surface (TBCS) was closely related to the dimension of the surgical trauma According to Schmitt and Bacchi,[2] S-100 protein is also useful as a tumor marker in diagnostic immunocytochemistry.
