Myelin Basic Protein (MBP) is a critical protein in neuro research, particularly for its role in the formation and maintenance of the myelin sheath. This sheath insulates nerve fibers, significantly increasing the speed of electrical signal transmission. Researchers use MBP to study myelination processes and demyelinating diseases such as multiple sclerosis, making it essential for understanding nerve function and pathology in various neurological conditions. Its expression helps in assessing the integrity and repair of myelin in the central nervous system.

What are the advantages of a recombinant monoclonal antibody?
This product is a recombinant monoclonal antibody, which offers several advantages including:

  • - High batch-to-batch consistency and reproducibility
  • - Improved sensitivity and specificity
  • - Long-term security of supply

Shipping conditions update: ambient shipping

This product will be delivered at ambient temperature instead of chilled – this is by design. Extensive stability testing confirmed that our products are suitable for shipment under ambient conditions and maintain expected quality.

Why the change?

It’s part of our commitment to more sustainable packaging solutions, with ambient deliveries using eco-friendly materials such as recyclable cardboard instead of polystyrene.

What you need to know

  • Ambient shipments come with a flyer explaining the below.
  • No ice will be included in ambient shipments, but mixed orders (ambient and cold-chain items) will still arrive with ice packs to protect temperature-sensitive products.
  • Warranty coverage remains fully valid, aligned with our validated shipping method.
  • Please store the product as per the datasheet instructions upon receipt.

Supplementary information

The myelin basic protein also referred to as MBP or MBP protein plays an important mechanical role in the central nervous system. It is a major component in the formation and stability of the myelin sheath which wraps around nerve fibers to ensure efficient neural signaling. The molecular weight of MBP can vary due to alternative splicing; one common form has a mass of about 18.5 kDa. MBP is expressed predominantly in oligodendrocytes within the brain and spinal cord where it helps form the myelin sheath. MBP2 is another variant that may be mentioned in some contexts.
Biological function summary

MBP is not just a passive structural element; it binds and interacts with lipids and other proteins to maintain the compact structure of the myelin sheath. MBP forms part of a complex that includes various other proteins and lipids ensuring the stability and function of myelin. Misfolding or altered expression of MBP can compromise myelin integrity affecting the insulation of neural pathways and signal transmission.

Pathways

MBP is an essential component in the pathways of myelination and neural plasticity. It plays a role in the signaling pathways that stimulate the development and maintenance of the myelin sheath. The protein interacts with other elements of the myelin sheath such as proteolipid protein (PLP) and myelin-associated glycoprotein (MAG) to coordinate its formation and repair processes.

MBP is linked closely to multiple sclerosis (MS) and other demyelinating conditions. Damage to or autoimmunity against MBP leads to the degradation of the myelin sheath contributing to the neurological symptoms in MS. The protein interacts with elements of the immune system with autoantibodies targeting MBP often found in MS patients. Another disorder associated with MBP dysfunction is Charcot-Marie-Tooth disease where abnormal MBP expression and structure can impact nerve function.

Target data

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.
