Rat MAG (Myelin Associated Glycoprotein) ELISA (Small Sample Volume)

The test principle applied in this kit is Sandwich enzyme immunoassay. The microtiter plate provided in this kit has been pre-coated with an antibody specific to Rat MAG. Standards or samples are added to the appropriate microtiter plate wells then with a biotin-conjugated antibody specific to Rat MAG. Next, Avidin conjugated to Horseradish Peroxidase (HRP) is added to each microplate well and incubated. After TMB substrate solution is added, only those wells that contain Rat MAG, biotin-conjugated antibody and enzyme-conjugated Avidin will exhibit a change in color. The enzyme-substrate reaction is terminated by the addition of sulphuric acid solution and the color change is measured spectrophotometrically at a wavelength of 450nm ± 10nm. The concentration of Rat MAG in the samples is then determined by comparing the OD of the samples to the standard curve. Protein Function: Adhesion molecule that mediates interactions between myelinating cells and neurons by binding to neuronal sialic acid-containing gangliosides and to the glycoproteins RTN4R and RTN4RL2 (PubMed:8995428, PubMed:9298990). Not required for initial myelination, but seems to play a role in the maintenance of normal axon myelination. Protects motoneurons against apoptosis, also after injury, protection against apoptosis is probably mediated via interaction with neuronal RTN4R and RTN4RL2. Required to prevent degeneration of myelinated axons in adults, this probably depends on binding to gangliosides on the axon cell membrane (By similarity). Negative regulator of neurite outgrowth, in dorsal root ganglion neurons the inhibition is mediated primarily via binding to neuronal RTN4R or RTN4RL2 and to a lesser degree via binding to neuronal gangliosides (PubMed:17640868). In cerebellar granule cells the inhibition is mediated primarily via binding to neuronal gangliosides (PubMed:17640868). In sensory neurons, inhibition of neurite extension depends only partially on RTN4R, RTN4RL2 and gangliosides (PubMed:19367338). Inhibits axon longitudinal growth (PubMed:9298990). Inhibits axon outgrowth by binding to RTN4R (By similarity). Preferentially binds to alpha-2,3-linked sialic acid (PubMed:8995428). Binds ganglioside Gt1b (PubMed:8995428) [The Uniprot Consortium]
