Product Details
This non-therapeutic biosimilar antibody uses the same variable regions as the therapeutic antibody Donanemab, making it ideal for research use. Donanemab is a humanized IgG1Īŗ anti-human APP antibody, and it specifically reacts with abeta 42 (AĪ²42), a pyroglutamate form of AĪ² that is aggregated in amyloid plaques during the pathogenesis of Alzheimerās disease (AD). AĪ²42 results from an aberrant processing of amyloid-Ī² protein precursor (APP or AĪ²PP). The initial cleavage of APP is caused by either Ī±- secretase or Ī²-secretase (or BACE1). sAPPĪ± and the Ī±-C-terminal fragment (Ī±-CTF or APP-C83) are produced by Ī±-secretase cleavage of APP, whereas sAPPĪ² and the Ī²-C-terminal fragment (Ī²-CTF or APP-C99) are produced by Ī²-secretase cleavage. Ī³-secretase further cleaves C83 and C99, yielding the P3 peptide and AĪ², respectively. Depending on the location of the Ī³-secretase cleavage, AĪ² can have a length of 37-43 amino acids in its peptide sequence. The two main AĪ² species are AĪ²42 and AĪ²40. In early AD pathology, AĪ² species play a critical role by seeding toxic oligomeric species with AĪ²42 being more preferentially depositing in amyloid plaques than AĪ²40. Donanemab specifically recognizes AĪ² p3-42 (AĪ²42) and it is reported to impede the progression of AD by clearing plaques through microglial-mediated phagocytosis in mice without causing microhemorrhages. Donanemab biosimilar antibodies are commonly used for in vitro and in vivo studies involving Alzheimer's disease and Down syndrome experimental models.Specifications
