  • Function
    The classic group of MBP isoforms (isoform 4-isoform 14) are with PLP the most abundant protein components of the myelin membrane in the CNS. They have a role in both its formation and stabilization. The smaller isoforms might have an important role in remyelination of denuded axons in multiple sclerosis. The non-classic group of MBP isoforms (isoform 1-isoform 3/Golli-MBPs) may preferentially have a role in the early developing brain long before myelination, maybe as components of transcriptional complexes, and may also be involved in signaling pathways in T-cells and neural cells. Differential splicing events combined with optional post-translational modifications give a wide spectrum of isomers, with each of them potentially having a specialized function. Induces T-cell proliferation.
  • Tissue specificity
    MBP isoforms are found in both the central and the peripheral nervous system, whereas Golli-MBP isoforms are expressed in fetal thymus, spleen and spinal cord, as well as in cell lines derived from the immune system.
  • Involvement in disease
    Note=The reduction in the surface charge of citrullinated and/or methylated MBP could result in a weakened attachment to the myelin membrane. This mechanism could be operative in demyelinating diseases such as chronical multiple sclerosis (MS), and fulminating MS (Marburg disease).
  • Sequence similarities
    Belongs to the myelin basic protein family.
  • Developmental stage
    Expression begins abruptly in 14-16 week old fetuses. Even smaller isoforms seem to be produced during embryogenesis; some of these persisting in the adult. Isoform 4 expression is more evident at 16 weeks and its relative proportion declines thereafter.
  • Post-translational
    Several charge isomers of MBP; C1 (the most cationic, least modified, and most abundant form), C2, C3, C4, C5, C6, C7, C8-A and C8-B (the least cationic form); are produced as a result of optional PTM, such as phosphorylation, deamidation of glutamine or asparagine, arginine citrullination and methylation. C8-A and C8-B contain each two mass isoforms termed C8-A(H), C8-A(L), C8-B(H) and C8-B(L), (H) standing for higher and (L) for lower molecular weight. C3, C4 and C5 are phosphorylated. The ratio of methylated arginine residues decreases during aging, making the protein more cationic.
    The N-terminal alanine is acetylated (isoform 3, isoform 4, isoform 5 and isoform 6).
    Arg-241 was found to be 6% monomethylated and 60% symmetrically dimethylated.

  • ab7349 staining Myelin Basic Protein in human trigeminal ganglia tissue sections by Immunohistochemistry (IHC-P - paraformaldehyde-fixed, paraffin-embedded sections). Tissue was fixed with paraformaldehyde and blocked with 10% serum for 1 hour at 20°C; antigen retrieval was by heat mediation in citrate buffer, pH 6.0. Samples were incubated with primary antibody (1/1000 in 10% NDS) for 16 hours at 22°C. ab150165, a goat anti-rat IgG H&L (Alexa Fluor® 488) preadsorbed polyclonal (1/1000) was used as the secondary antibody.

Thank you for your enquiry. I do not have the accession number for the immunogen; however, the amino acid sequence to which the antibody binds is DENPVV. I have updated the datasheet for future reference. I hope this information helps, please do not hesitate to contact us if you need any more advice or information.

Before I can recommend a secondary antibody to you, I would need to know the following:

What application are you using, IHC-P or IHC-Fr?

Shall the antibody be conjugated with an enzyme or with a Fluorochrom?

Will you use the primary antibody in co-immunostaining experiments with other primary antibodies?

Thank you for your enquiry.

I can confirm that the anti-Myelin Basic Protein antibody [12] - Oligodendrocyte Marker ab7349 is sold as tissue culture supernatant. Unpurified antibodies, such as those sold as whole antiserum, ascites or tissue culture supernatant will not have a concentration stated on the datasheet. Antibody concentration is usually determined by protein assay, and serum / ascites / tissue culture supernatant will contain a lot of other proteins, which means the antibody quantification would not be accurate.

I can confirm that for tissue culture supernatant, concentration of antibody is known to very between 1 - 3 mg/ml. I would suggest starting your experiment with a dilution of 1/1000 and optimise further to achieve the best results. A checkerboard titration of the dilution of the antibody could be performed.

I am sorry we are not able to provide an exact concentration on this occasion, but hope this information will be helpful to you. If you have any further questions, please do not hesitate to contact us.
