Background:
CD22 is a lineage-restricted B-cell antigen that is expressed solely in on B-chronic lymphocytic leukemia, hairy cell leukemia, acute lymphocytic leukemiathe and Burkitt’s lymphoma. The predecessor of Moxetumab pasudotox (MxP), named BL22, was first created based on the antibody RFB4 which specifically binds to CD22. This antibody was used to generate a recombinant immunotoxin in which a stabilized Fv segment by a disulfide bond is fused to the Pseudomonas exotoxin A (PE38) which does not have the cell-binding portion. MxP appears as an improved form of BL22 by the mutation of the Fv region and the antibody phage-displayed. As well the residues SSY in the heavy chain are mutated to THW. It was developed by Astra Zeneca and FDA approved on September 13, 2018, after being granted the status of Fast Track, Priority Review and Orphan Drug designations.
Intended Use:
For Estimation of Moxetumomab in human serum and plasma. Krishgen’s range of KRIBIOLISA kits are developed using the high quality raw materials and are thoroughly validated for accuracy and precison. They allow quantification of serum or plasma protein drug levels, and can be used for biosimilar and generics research to understand pharmacokinetic properties of the drug. Please note the kit has not been optimized to be used for any other animal species. Should you require a specific sera tested, please connect with us for optimisation.
