Cat. No. | MABL-056 |
Name | Anti-MOG mAbs |
Clone No. | AFD-M3-31 |
From | Recombinant Antibody |
Isotype | Engineer antibody |
Application | Blocking, ELISA, IHC |
Secies Reactivity | Rat, Human |
Basic Information | |
Specificity | Is displaced by M38 and M45 and is weakly displaced by M26 although this is not mutual which may suggest the M26-mediated displacement is conformationally driven, although this has not been confirmed. The epitope recognised is a structural epitope, shown by the lack of recognition of linear MOG peptides. Binds MOG expressed in CHO cells. |
Alternative Name | Myelin oligodendrocyte glycoprotein; rMOG; hMOG |
UniProt | Q63350 |
Immunogen | Callithrix jacchus marmosets were used, and experimental allergic encephalomyelitis was induced by the injection of rat MOG (aa1-125) into the marmosettes. The rMOG was expressed in E. coli and purified to homogeneity. The animals were killed 4-70 days after the onset of symptoms of EAE. Bone marrow and spleen cells were obtained from an immunized C. jacchus, the RNA extracted with Trizol reagent and rtPCR used to generate cloning inserts containing Fab portions of IgGk. Phage display was then used to select for the MOG-reactive Fab fragments using the pCOMB3H phage display vector, and binding confirmed using an ELISA. |
Application Notes | This antibody has been proposed for the diagnosis and prognosis of multiple sclerosis (MS) or allergic encephalomyelitis (EAE) by using competition assays to determine if there are autoantibodies present in an individual. It has also been proposed that it could be used to predict the severity of the MS or EAE by detecting the proportion of conformation-specific autoantibodies to linear epitope autoantibodies. This antibody has been used in ELISAs and competition assays to characterise its epitope in relation to other antibodies generated against MOG. It was originally generated and tested as a Fab fragment (vod Budingen et al, 2002). This antibody has also shown to bind to hMOG expressed in a CHO cell line (Lalive et al, 2006). Analysis has also been done on the amino acid sequence of this antibody (von Budingen et al, 2006). |
