General description

Monoclonal Anti-Phosphacan (mouse IgM isotype) is derived from the hybridoma 122.2 produced by the fusion of mouse myeloma cells (P3X cells) and splenocytes from BALB/c mice immunized with rat brain proteoglycans. Chondroitin sulfate proteoglycans are neural cell adhesion molecules (NCAM) ligands present in the brain extracellular matrix (ECM). Phosphacan protein is expressed mainly in astrocytes and is a ligand for NCAM. Phosphacan is the soluble extracellular domain of the receptor-type transmembrane protein tyrosine phosphatase (RPTPb).

Immunogen

rat brain proteoglycans.

Application

Monoclonal Anti-Phosphacan antibody produced in mouse has been used in:
  • immunoblotting
  • immunohistochemistry
  • immunocytochemistry.

Biochem/physiol Actions

Phosphacan levels elevates during late embryogenesis. It reaches a plateau two weeks postnatal before reaching stable. Receptor-type transmembrane protein tyrosine phosphatase (RPTPb) functions to promote primary tecal neurons neurite growth, neural migration and also induces cell adhesion. Both phosphacan and RPTPb can bind to NCAM and tenascin-C and −R. Phosphacan can oppose RPTPb by competing for its binding sites. Both in hippocampal and spinal cord neurons, phosphacan can affect neuronal adhesion and neurite outgrowth.

Physical form

Solution in 0.01 M phosphate buffered saline, pH 7.4, containing 15 mM sodium azide.

Short seizure episodes are associated with remodeling of neuronal connections. One region where such reorganization occurs is the hippocampus, and in particular, the mossy fiber pathway. Using genetic and pharmacological approaches, we show here a critical role in vivo for

Cell death and differentiation, 25(8), 1503-1516 (2018-02-06)
In response to stroke, astrocytes become reactive astrogliosis and are a major component of a glial scar. This results in the formation of both a physical and chemical (production of chondroitin sulfate proteoglycans) barrier, which prevent neurite regeneration that, in
