MIC-Drop technology speeds gene identification (IMAGE) University of Utah Health Caption Which genes are MIC-Drop is a new CRISPR-based technology for rapidly and efficiently screening the functions of hundreds of genes in zebrafish to better understand human health and disease. A glass needle filled with MIC-Drops (colored droplets) is used to inject fertilized zebrafish eggs (translucent spheres). The MIC-Drops are dyed different colors for easy visualization. MIC-Drops are one-billionth of a liter in volume, and each one contains the materials needed to barcode and disrupt a single gene.
