C3aR antibody | knockout validation | Hycult Biotech HM1123

This is a knockout-validated antibody summary, based on the publications "Astrocyte-Microglia Cross Talk through Complement Activation Modulates Amyloid Pathology in Mouse Models of Alzheimer's Disease", as cited below [1] and “Microglia Exacerbate White Matter Injury via Complement C3/C3aR Pathway After Hypoperfusion” for immunohistochemistry (figure 5a) [2]. Labome curates formal publications to compile a list of antibodies with unambiguous specificity within Validated Antibody Database (VAD).
