O protocolo descreve uma abordagem de alto rendimento para determinação de estruturas de proteínas de membrana usando tomografia crio-eletrônica e processamento de imagens 3D. Abrange os detalhes da preparação da amostra, coleta de dados, processamento e interpretação dos dados, e conclui com a produção de um alvo representante para a abordagem, o HIV-1 glicoproteína do envelope. Estes procedimentos computacionais são projetados de uma forma que permite aos pesquisadores e estudantes para trabalhar remotamente e contribuir para processamento de dados e análise estrutural.
