The common marmoset (Callithrix jacchus) is an important nonhuman primate model in biomedical research, but the lack of a standardized necropsy protocol limits reproducibility and data quality. Here, we present a protocol for necropsy and tissue processing of the common marmoset (Callithrix jacchus). We describe steps for anesthesia, external observation, laparotomy, blood collection, organ sampling, and fixation. We then detail procedures for trimming, tissue processing, and embedding. This protocol enables researchers to obtain high-quality, reproducible samples for histopathological analyses.
