Description
Human MOG (Myelin Oligodendrocyte Glycoprotein) ELISA Kit
The Human MOG (Myelin Oligodendrocyte Glycoprotein) ELISA Kit is specifically designed for the accurate detection of MOG levels in human serum, plasma, and cell culture supernatants. This kit offers high sensitivity and specificity, guaranteeing precise and consistent results for a variety of research purposes.MOG is a key protein found in the central nervous system that is crucial for myelin sheath stability and function.
Alterations in MOG levels have been associated with autoimmune diseases such as multiple sclerosis, making it a valuable biomarker for studying these conditions and developing potential treatments.With its reliable performance and ease of use, the Human MOG ELISA Kit is an essential tool for researchers investigating the role of MOG in neurological disorders and autoimmune diseases.

This ELISA kit uses Sandwich-ELISA as the method. The micro ELISA plate provided in this kit has been pre-coated with an antibody specific to Human MOG. Standards or samples are added to the appropriate micro ELISA plate wells and combined with the specific antibody. Then a biotinylated detection antibody specific for Human MOG and Avidin-Horseradish Peroxidase (HRP) conjugate are added to each micro plate well successively and incubated. Free components are washed away. The substrate solution is added to each well. Only those wells that contain Human MOG, biotinylated detection antibody and Avidin-HRP conjugate will appear blue in color. The enzyme-substrate reaction is terminated by adding Stop Solution and the color turns yellow. The optical density (OD) is measured spectrophotometrically at a wavelength of 450 nm ± 2 nm. The OD value is proportional to the concentration of Human MOG. The concentration of Human MOG in samples can be calculated by comparing the OD of the samples to the standard curve.
| UniProt Protein Function: | MOG: Mediates homophilic cell-cell adhesion. Minor component of the myelin sheath. May be involved in completion and/or maintenance of the myelin sheath and in cell- cell communication. Defects in MOG are the cause of narcolepsy type 7 (NRCLP7). Neurological disabling sleep disorder, characterized by excessive daytime sleepiness, sleep fragmentation, symptoms of abnormal rapid-eye-movement (REM) sleep, cataplexy, hypnagogic hallucinations, and sleep paralysis. Cataplexy is a sudden loss of muscle tone triggered by emotions, which is the most valuable clinical feature used to diagnose narcolepsy. Human narcolepsy is primarily a sporadically occurring disorder but familial clustering has been observed. Belongs to the immunoglobulin superfamily. BTN/MOG family. 10 isoforms of the human protein are produced by alternative splicing. |
| UniProt Protein Details: | Protein type:Membrane protein, integral; Membrane protein, multi-pass Chromosomal Location of Human Ortholog: 6p22. 1 Cellular Component: integral to membrane; plasma membrane Biological Process: central nervous system development; positive regulation of MyD88-dependent toll-like receptor signaling pathway; cell adhesion Disease: Narcolepsy 7 |
| NCBI Summary: | The product of this gene is a membrane protein expressed on the oligodendrocyte cell surface and the outermost surface of myelin sheaths. Due to this localization, it is a primary target antigen involved in immune-mediated demyelination. This protein may be involved in completion and maintenance of the myelin sheath and in cell-cell communication. Alternatively spliced transcript variants encoding different isoforms have been identified. [provided by RefSeq, Jul 2008] |

As the OD values of the standard curve may vary according to the conditions of the actual assay performance (e. g. operator, pipetting technique, washing technique or temperature effects), the operator should establish a standard curve for each test. Typical standard curve and data is provided below for reference only.
