IDH1/2 mutations are early and frequent genetic alterations, are specific to a single codon in the conserved and functionally important Arginine 132 (R132) in IDH1 and Arginine 172 (R172) in IDH2. We previously established several monoclonal antibodies (mAbs), which are specific for IDH1 mutations: clones IMab-1 or HMab-1 against IDH1-R132H or clone SMab-1 against IDH1-R132S. However, specific mAbs against IDH2 mutations have not been reported. To establish IDH2-mutation-specific mAbs, we immunized mice or rats with each... View Source
