The EMSA – Teaching an Old Dog New Tricks

By Alex Chen | April 17, 2019

Probing Nucleic Acid-Protein Interactions with EMSA The electrophoretic mobility shift assay (EMSA) is a powerful technique for detecting specific-binding of nucleic acid-protein complexes. Over the past 30 years, EMSA has been the “go to assay” to investigate the qualitative interactions between nucleic acids (DNA or RNA) and nucleic-acid binding proteins. Through the use of radio-labeled…

Mastering the Art of Isolating Pure Alveolar Epithelial Cells

By Deblina Chakraborty | April 16, 2019

Alveolar epithelial cells (AECs) are one of the major types of lung cells that can be used to analyze the response of lung epithelia to external agents. AECs from mouse lungs can thus be utilized as an in vitro model of diseases. AECs are indispensable for studying lung development, injury, and repair. People working on…
