18th to 19th November I participated the 3rd International conference Proteomics-2019 (Amsterdam, Holland). This conference invited all the participants from all over the world and included plenary, keynote presentations, oral talks, poster presentations, workshop/symposium, and exhibitions. Proteomics-2019 provided the excellent opportunity to meet experts, exchange information, and strengthen the collaboration among researchers, associate professors, and scholars from both academia and industry.
