Looking Outwards: Isolation of Cyanobacterial Released Carbohydrate Polymers and Proteins Carlos Flores1,2,3, Paula Tamagnini1,2,4 1Bioengineering and Synthetic Microbiology Group, Instituto de Investigação e Inovação em Saude, Universidade do Porto, 2Instituto de Biologia Celular e Molecular, Universidade do Porto, 3Instituto de Ciências Biomédicas Abel Salazar, 4Departamento de Biologia, Faculdade de Ciências, Universidade do Porto Here, protocols for the isolation of cyanobacterial released carbohydrate polymers and isolation of their exoproteomes are described. Both procedures embody key steps to obtain polymers or proteins with high purity degrees that can be used for further analysis or applications. They can also be easily adapted according to specific user needs.
Interfacing Microfluidics with Microelectrode Arrays for Studying Neuronal Communication and Axonal Signal Propagation Cátia D.F. Lopes1,2, José C. Mateus1,2,3, Paulo Aguiar1,2 1i3S - Instituto de Investigação e Inovação em Saúde, Universidade do Porto, 2INEB - Instituto de Engenharia Biomédica, Universidade do Porto, 3ICBAS - Instituto de Ciências Biomédicas Abel Salazar, Universidade do Porto This protocol aims to demonstrate how to combine in vitro microelectrode arrays with microfluidic devices for studying action potential transmission in neuronal cultures. Data analysis, namely the detection and characterization of propagating action potentials, is performed using a new advanced, yet user-friendly and freely available, computational tool.
Normal and Malignant Muscle Cell Transplantation into Immune Compromised Adult Zebrafish Inês M. Tenente*1,2,3, Qin Tang*1,2, John C. Moore1,2, David M. Langenau1,2 1Molecular Pathology, Cancer Center and Center for Regenerative Medicine, Massachusetts General Hospital, 2Harvard Stem Cell Institute, 3GABBA - Instituto de Ciências Biomédicas Abel Salazar, Universidade do Porto Here, we present a protocol for cell transplantation of zebrafish skeletal muscle and embryonal rhabdomyosarcoma (ERMS) into adult immune compromised rag2E450fs homozygous mutant zebrafish. This protocol allows for the efficient analysis of regeneration and malignant transformation of muscle cells.
