Cayman Citrullinated Myelin Basic Protein (R122) Monoclonal Antibody (Clone 1H1)

Citrullinated myelin basic protein (citMBP) is a citrullinated form of MBP, a protein that is integral to myelin stability in the CNS. MBP contains 19 arginine residues that can be citrullinated by peptidylarginine deiminases (PADs), decreasing the positive charge of MBP.^, The loss of positive charge disrupts MBP-lipid interactions, leading to myelin destabilization and loss and increases its susceptibility for degradation. MBP is degraded by the myelin-associated protease cathepsin D, which leads to exposure and release of immunodominant epitopes.^, The percentage of MBP that is citrullinated is increased in the postmortem brain from patients with multiple sclerosis (MS), with an even greater percentage citrullinated in Marburg disease, a more severe form of MS. citMBP isolated from patients with multiple sclerosis (MS) is degraded by cathepsin D at a higher rate than MBP isolated from healthy controls.^, Cayman’s Citrullinated Myelin Basic Protein (R122) Monoclonal Antibody (Clone 1H1) can be used for ELISA, immunohistochemistry (IHC), and Western blot applications. The antibody recognizes citMBP from human and mouse samples and was generated using a peptide immunogen containing citrulline at R122 (human myelin basic protein sequence, isoform 5).
