Application notes
(see key)
|
Recommended dilutions IHC-P: 1/50 - 1/500. Use Bouin fixed tissue. Do not perform antigen retrieval. (see Hellani et al). IHC-FoFr: 1/100. Following perfusion fixation fix tissue overnight in 4%PFA. WB: 1/200 - 1/5000. Block in Tris-buffered saline (TBS) containing 1% BSA overnight at 4C. Detects a band of approximately 22 kDa (predicted molecular weight: 22 kDa). Possible oligomerisation or polimerisation of the protein have been reported and can lead to high MW bands.
Not yet tested in other applications. Optimal dilutions/concentrations should be determined by the end user.

Relevance

Oligodendrocyte specific protein (OSP), also known Claudin 11, is the third most abundant component of central nervous system myelin. The claudin superfamily consists of many structurally related proteins. These proteins, which include claudin 1 through 18, are located in both epithelial and endothelial cells in all tight junction bearing tissues. Claudins, which consist of four transmembrane domains and two extracellular loops, make up tight junction strands. There is growing evidence that OSP/Claudin 11 determines the permeability between layers of myelin sheaths via focal adhesion. Its expression is highly regulated during development, suggesting that it may play an important role in the growth and differentiation of oligodendrocytes and other cells outside the CNS. In addition, the protein is a candidate autoantigen in the development of autoimmune demyelinating disease.

Immunohistochemistry - Free Floating - Oligodendrocyte Specific Protein OSP antibody - Oligodendrocyte Marker (ab7474)
Immunofluorescent staining for OSP obtained with OSP antibody (ab7474) in rat brain cortex. The picture shows oligodendrocyte immunostaining in the cingular cortex. Picture taken with X20 objective, cells stained are ~30microns in diameter. Animals were intracardially perfused with 4% PFA. Tissue was post-fixed overnight in the same fixative, cryoprotected in 20% sucrose and frozen in OCT. Protocol : free floating IHC on 30um cryostat sections. Primary antibody ab7474 was used at 1/100 and incubated overnight at RT. Secondary antibody, Alexa fluor 488 at 1/1000, incubated for 2h at RT.
