Application

The antibody may be used in various immunochemical techniques including Immunohistochemistry and Immunoblotting (~200 kDa).1-7

Biochem/physiol Actions

Neurofilaments undergo post-translational modifications including different levels of phosphorylation, which has been suggested to modulate their function by influencing the interaction between neurofilament and cytoplasmic organelles. Neurofilaments are built from three intertwined protofibrils of apparent molecular weights [68 (L), 160 (M) and 200 (H) kDa] which are themselves composed of two tetrameric protofilament complexes of monomeric proteins. Neurofilament 200 also known as Neurofilament heavy polypeptide (H-subunit), NF-H, NEFH or 200 kDa neurofilament protein, has an important function in mature axons that is not subserved by the two smaller neurofilament proteins.

General description

Neurofilaments are type of intermediate filaments (IFs) that serve as major elements of the cytoskeleton supporting the axon cytoplasm of neuronal cells. IFs are components of most eukaryotic cells and significantly differ from other cytoskeletal elements of the cell, namely microtubules and microfilaments.

Immunogen

Neurofilaments purified from pig spinal cord

Physical form

Supplied as a solution in 0.01 M phosphate buffered saline pH 7.4, containing 15 mM sodium azide as a preservative.

Specificity

Monoclonal Anti-Neurofilament 200, also known as Neurofilament-H or Heavy subunit, specifically recognizes the phosphorylated H tail of Neurofilament 200 and shows no reactivity on enzymatically dephosphorylated neurofilaments.2 The antibody shows reactivity with neurofilaments in the central and peripheral nervous systems from human1, pig1, mouse3, rat4, chicken3, guinea pig3, feline3 and bovine3 origin.

Storage and Stability

For continuous use, store at 2-8°C for up to one month. For extended storage, freeze in working aliquots. Repeated freezing and thawing is not recommended. If slight turbidity occurs upon prolonged storage, clarify the solution by centrifugation before use. Working dilution samples should be discarded if not used within 12 hours. Protect from prolonged exposure to light.
