NFM 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 NFM protein into laying hens and purifying the IgY fraction from eggs collected from hyper-immunized hens. After several boosts, hens were co-boosted with recombinant NFM protein expressed in bacteria. These antibodies have been validated with human, mouse and rat tissues.

Volume: 200 µL

Concentration: 2 mg/mL

Clonality: Polyclonal

Host Species: Chicken

Species Reactivity:Human, Mouse, Rat

Applications: ICC, IHC, WB

Protein Name / Synonyms: Neurofilament medium polypeptide (NF-M) (160 kDa neurofilament protein) (Neurofilament 3) (Neurofilament triplet M protein)

Target Description: Human Neurofilament Medium Chain (NFM) is a 102,448 dalton protein (916 amino acids) expressed in CNS and PNS neurons. This cytoskeletal protein is normally phosphorylated in vivo and its extent of phosphorylation correlates with different states of axonal growth and stabilization. These observations have led to the hypothesis that the NFM protein cross-links adjacent neurofilament strands and contributes to the structural integrity of the axon.

Gene ID: NEFM NEF3 NFM

Antibody Registry ID (RRID): AB_2313554

Physical State: Liquid

Production Notes: NFM 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 NFM protein into laying hens. 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: 150 kDa

Western Blot Dilution Range: 1:1000-1:2000

IHC Dilution Range: 1:1000-1:2000

Quality Control

Quality assurance analysis was performed using immunohistochemistry (at a dilution of 1:5000) 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.

鸡的概念 在一次会议上，他与同事的一次谈话说服了西蒙博士再次尝试制造这种抗体，但是尝试把鸡作为宿主——鸡在进化上与包括人类在内的哺乳动物完全不同。结果表明:人蛋白抗原具有高度的免疫原性，抗体产量异常高，免疫试剂结合紧密，特异性高。 今天的Aves 从那时起，Aves Labs开创了在蛋白质中寻找高免疫原性肽序列的新算法，开发了针对鸡抗体的新的亲和纯化方法，并开发了许多其他有用的试剂，如BlokHen®阻断试剂和PrecipHen®免疫沉淀试剂。Aves实验室继续开发针对神经特异性抗原和表位标签的新型抗体试剂，以促进神经科学和分子生物学领域的科学进步。
