Nucleic Acid Stains

Introduction

The nucleus of the cell is a membrane-bound organelle that includes the nuclear envelope, nucleoli, and nuclear lamina and is the site of gene expression. Nuclear structure can be selectively visualized using nucleic acid stains. GeneCopoeia offers a selection of nucleic acid stains to stain live or dead cells/tissues,  providing a means to locate the nucleus and follow nuclear changes throughout cellular processes, from mitosis to apoptosis.
