RESUMO
SDS-PAGE and LC-MS/MS were used to identify proteins in Saigae Tataricae Cornu (SAH) and Caprae Hircus Cornu (GH). Trypsin digestion peptides from SAH and GH were obtained by in-gel digestion, after which nano LC-LTQ/Orbitrap MS was used to identify the proteins in SAH and GH. As a result, in total 101 proteins and 140 proteins were identified form SAH and GH, respectively. There were 43 keratins (KRTs) and keratin-associated proteins (KAPs) identified, which account for 42.6% of the 101 proteins in SAH. The proportion of KRTs and KAPs in GH was 37.1%. The comparison between SAH and GH showed that the main common components in SAH and GH were structural molecule activity proteins, such as KRTs and KAPs. In the present study, we provide determination method and experimental data for investigating the material basis of SAH and GH, guiding the investigation on effective material basis and quality standard of animal horn derived TCMs.
