S-100A and S-100B proteins are two members of the S-100 family of proteins.
S-100A is composed of an alpha and beta chain whereas S-100B is
composed of two beta chains. S-100 protein is reported to be expressed in
neuroectodermal tissue, including nerves and melanocytes. Langerhans
cells in skin and interdigitating reticulum cells in the paracortex of lymph
nodes are also reported to express S-100 protein. It is noteworthy that S-100
protein is highly soluble and may be eluted from frozen tissue during
immunohistochemical procedures.
Product Specific Information
NCL-S100 is specific for the A form of S-100 and so is not recommended for
the staining of neural elements. NCL-S100p, NCL-L-S100p and RTU-S100p
may require enzyme pretreatment in some cases and are also reactive with
S-100 protein from cow, chicken, pig, dog, cat, monkey, horse, mouse and rat.
NCL-S100 may require heat induced epitope retrieval (HIER) in some cases.

S100A7 (Psoriasin)
Clone 3DC
1 mL liquid NCL-L-S100-A7 P (HIER)
Reference Range
S100A7, also known as psoriasin, is a member of the S-100 gene family of
calcium binding proteins which regulate a variety of intracellular and
extracellular processes. It is largely, although not entirely, reported to be
confined to stratified squamous epithelium. Reports indicate that in breast
cancer, high levels of S100A7 are associated with estrogen and
progesterone receptor negative status and nodal metastasis. It is also
reported to be expressed in abnormal keratinization in squamous cell
carcinoma.

In normal skeletal muscle, dystrophin, the protein product of the gene which
is defective in Duchenne and Becker muscular dystrophy, is attached to the
muscle membrane via a complex of at least seven proteins (dystrophin
associated glycoproteins, DAGs). Dystrophin-deficient muscle shows a
generalized reduction in DAG labeling. Recent studies have shown that
expression of different members of the dystrophin glycoprotein complex are
altered in several types of muscular dystrophy: the picture is complex and
disease classification is currently under review. For example, individuals
with LGMD2D have mutations in the gene for alpha-sarcoglycan, those with
LGM2E have mutations in the beta-sarcoglycan gene, and those with LGM2F
have mutations in the delta-sarcoglycan gene. Also, many individuals with
severe childhood autosomal recessive muscular dystrophy (SCARMD) show
defective expression in the sarcoglycan subgroup of complex proteins
which includes alpha-sarcoglycan (adhalin) and gamma sarcoglycan. As the
sarcoglycans function together as a subcomplex, individuals with mutations
in any one of the sarcoglycan genes usually show reduced expression for
the whole group, but the reduction may be most severe for the mutated
single protein. Labeling for beta-spectrin is necessary to monitor membrane
integrity.
