Product DescriptiongoogleChicken anti-Neurofilament heavy polypeptide, phosphorylated, (pNF-H), Polyclonal Antibody (Unconjugated), suitable for WB, ELISA and Immunostaining.
Alternative NamesNF-H; NFH; NF-200; NF200; NF-H; NEFH; N52; Neurofilament heavy polypeptide; Neurofilament triplet H protein; 200 kDa neurofilament protein; KIAA0845
Application(s)ELISA, IF, ICC, IHC, WB
Antibody HostChicken
Antibody TypePolyclonal
SpecificitySpecies cross-reactivity includes human, rat, mouse, cow, pig, horse and dog. This antibody reacts with phosphorylated NF-H and is seen as a band at approx 200 kDa in WB. Refer to publication by Shaw et al (2005) for the use of this antibody in an ELISA to detect NF-H. Predicted to react with other mammalian tissues due to sequence homology.
Species ReactivityBovine, Dog, Horse, Human, Mouse, Other Mammals (Predicted), Pig, Rat
Immunogen DescriptionThis antibody has been made against biochemically isolated NF-H purified from bovine spinal cord.
Application DetailsWestern blot (WB), Immunocytochemistry (ICC) / Immunofluorescence (IF), and Immunohistochemistry (IHC). A dilution of 1:20,000-50,000 is recommended for WB. A dilution of 1:20,000 is recommended for ICC/IF and IHC. Biosensis recommends optimal dilutions/concentrations should be determined by the end user.

Scientific BackgroundNeurofilaments are the 10nm or intermediate filament proteins found specifically in neurons, and are composed predominantly of three major proteins called NF-L, NF-M and NF-H, though other filament proteins may be included also. The major function of neurofilaments is likely to control the diameter of large axons. NF-L is the neurofilament light or low molecular weight polypeptide and runs on SDS-PAGE gels at 68-70kDa with some variability across species. Antibodies to NF-L are useful for identifying neuronal cells and their processes in cell culture and sectioned material. NF-L antibody can also be useful for the visualization of neurofilament rich accumulations seen in many neurological diseases, such as Lou Gehrig’s disease (ALS), giant axon neuropathy, Charcot-Marie Tooth disease and others.

Image of a rat cerebellum section by Immunofluorescence and Immunohistochemistry. The section was stained with C-1386-50, Neurofilament heavy polypeptide, phosphorylated (pNF-H), Chicken pAb, (red, 1:5,000) and co-stained with product R-1374-50, Glial Fibrillary Acidic Protein (GFAP), Rabbit pAb (green). The blue is DAPI staining of nuclear DNA. Method: following transcardial perfusion with 4% paraformaldehyde, brain was post fixed for 24 hours, cut to 45 uM, and free floating sections were stained. The NF-H antibody labels network of axons of different neurons, while the GFAP antibody stains astrocytes.
Analysis by western blot of pNF-H expression in spinal cord lysates with C-1386-50, (green, 1:20,000) with strong bands at approx 200-220kDa corresponding to the phosphorlylated form of NF-H. Lane 1: MWM; Lane 2: rat; Lane 3: mouse; Lane 4: cow. The protein from different species is known to have different SDS-PAGE molecular weights, with large species generally expressing larger proteins. Smaller proteolytic fragments of NF-H are also detected in spinal cord preparations with this antibody. The antibody does not recognize non-phosphorylated forms of NF-H.
