Summary

This video is a technical talk from the MRC Laboratory of Molecular Biology, part of a series on solving problems with molecular techniques. It is divided into three main sections. First, Tim Stevens provides an introduction to bioinformatics, covering the types of data available in public databases (sequences, structures, interactions, pathways), how to search them (BLAST, HMMER, HHsuite), and how to use genome browsers and domain databases. He emphasizes the importance of choosing the right database and being aware of redundancy and E-values. Second, Kim Liu explains next-generation sequencing (NGS), focusing on the Illumina workflow, including library preparation, sequencing by synthesis, and data analysis. He also discusses various applications of NGS at the LMB, such as RNA-seq, ChIP-seq, and whole-genome sequencing, and mentions other sequencing technologies. Third, Cat Franco gives an overview of proteomics using mass spectrometry. She describes different workflows for identifying proteins from purified complexes or whole cell lysates, including sample preparation, LC-MS/MS, and data analysis. She highlights the importance of bioinformatics support for data interpretation and mentions the Mass Spectrometry and Proteomics Facility at the LMB. The talk is aimed at researchers and students with some background in molecular biology, providing practical guidance and resources.
