Antibody Microarray: A Technique to Study the Protein Expression of miRNA Treated Lung Cancer Cells

Abstract

Source: Hossian, A. et. al. Analysis of Combinatorial miRNA Treatments to Regulate Cell Cycle and Angiogenesis. J. Vis. Exp. (2019).

This video describes the technique to study the protein expression in miRNA transfected lung cancer cells by using antibody microarray to measure specific gene expression. In the featured protocol, we perform antibody microarray for the identification of the activity of a combinatorial miRNA treatment in halting cell cycle and angiogenesis.

Protocol

1. miR-143 and miR-506 transfection CAUTION: Use latex gloves, protective eyeglasses, and a laboratory coat while performing the described experiments. When required, use the biosafety cabinet with the cabinet fan on, without blocking the airways or disturbing the laminar airflow. Always set the protecting glass window to the appropriate height, as described by the manufacturer. Seed NSCLC A549 cells in a T25 cm2 flask/6/96 well plate in DMEM/F12K m…
