Specificity
|
This antibody recognizes all the S-100 isoforms, proteins of 21-24kDa identified as the A and B subunits of S100 protein. It stains schwannomas, ependymomas, astrogliomas, and almost all benign and malignant melanomas and their metastases. S100 protein is also expressed in the antigen presenting cells such as the Langerhans cells in skin and interdigitating reticulum cells in the paracortex of lymph nodes.

Relevance
|
S100 belongs to the family of calcium binding proteins such as calmodulin and troponin C. S100 proteins are localized in the cytoplasm and/or nucleus of a wide range of cells, and involved in the regulation of a number of cellular processes such as cell cycle progression and differentiation. S100 genes include at least 13 members which are located as a cluster on chromosome 1q21. S100A is composed of an alpha and beta chain whereas S100B is composed of two beta chains. S100 protein may function in stimulation of Ca2+ induced Ca2+ release, inhibition of microtubule assembly, and inhibition of protein kinase C mediated phosphorylation. Reduced expression of this protein has been implicated in cardiomyopathies. Immunoreactive S100 protein localizes in the cytoplasm and nuclei of astrocytes, Schwann's cells, ependymomas and astrogliomas. Ganglion cells do not stain for S100 protein. S100 can be detected in almost all benign naevi and malignant melanocytic tumours of the skin, and in Langerhans cells in the skin.

Immunohistochemistry (Formalin/PFA-fixed paraffin-embedded sections) - S100 antibody - Astrocyte Marker (ab868)
ab868 staining mouse brain tissue sections by IHC-P. Sections were formaldehyde fixed and permeabilized in 0.1% Triton-X100 in blocking solution prior to blocking in 100% BioGenex Power Block Universal Blocking Reagent for 10 minutes at 22°C. The primary antibody was diluted 1/1000 in 1% BSA in PBS pH 7.4 and incubated with the section for 1 hour at 22°C. A HRP polymer conjugated anti-rabbit antibody was used as the secondary. A tyramide Alexa Fluor® 594 conjugate was added and the signal was visualized using a fluorescent microscope and a rhodamine filter This image is courtesy of an anonymous Abreview
