NFH protein was purified from bovine spinal cords following the method of Delacourte et al. ["Study of the 10-nm-filament fraction isolated during the standard microtubule prepartion” (1980). Biochem. J. 191(2): 543-546], followed by Prepcell purification (Bio-Rad). Antibodies were prepared by injecting purified NFH protein into laying hens and purifying the IgY fraction from eggs collected from hyper-immunized hens. These antibodies have been found to cross-react with NFH protein from a variety of species, including human, mouse and rat.

Volume: 200 µL

Concentration: 1 mg/mL

Clonality: Polyclonal

Host Species: Chicken

Species Reactivity:Human, Mouse, Rat

Applications: ICC, IHC, WB

Protein Name / Synonyms: Neurofilament heavy polypeptide (NF-H) (200 kDa neurofilament protein) (Neurofilament triplet H protein)

Target Description: Human Neurofilament Heavy Chain (NFH) is a 115,378 dalton protein (1072 amino acids) that forms part of the neuronal cytoskeleton. NFH is physically associated with 10 nm intermediate filaments and is said to be one of the "neurofilament triplet" proteins, although it probably serves more to stabilize the cytoskeleton rather than as an integral structural component. NFH immunoreactivity is found in neuronal somata, dendrites and axons.

Gene ID: NEFH KIAA0845 NFH

Antibody Registry ID (RRID): AB_2313552

Physical State: Liquid

Production Notes: Chickens were immunized with NF-H protein purified from adult bovine brains. After repeated injections into the hens, immune eggs were collected, and the IgY fractions were purified from the yolks. Antibodies were diluted in the buffer described above, and then filter-sterilized.

Validation and Application Notes

Molecular Weight: 200-220 kDa

Western Blot Dilution Range: 1:2000-1:5000

IHC Dilution Range: 1:2000-1:5000

Quality Control

Quality assurance analysis was performed using immunohistochemistry (at a dilution of 1:50000) using fluorescein-labeled goat anti-chicken IgY (1:500 dilution, Aves Labs Cat.# F-1005) as the secondary reagent.

Storage

Store at 4°C in the dark. Under these conditions, the antibodies should have a shelf life of at least 12 months (provided they remain sterile). Do not freeze these antibodies unless you want to store them for longer periods of time. Note, however, that each time an antibody preparation is frozen, about half of its binding activity is lost.

NOTE

Aves Labs products are intended for use as research laboratory reagents. They are not intended for use as diagnostic or therapeutic reagents in humans.

二抗 该系列产品特点在于鸡IgY分子与哺乳动物IgG分子截然不同，因此由之制备的二抗不与来源于兔、小鼠或其他哺乳动物的一抗产生交叉反应，特别适用于组织学的免疫双标检测。该系列源于羊的二抗可交联荧光基团/HRP/生物素/琼脂糖，可广泛用于WB，免疫组化/免疫细胞化学及免疫共沉淀研究。
