Organelle stain selection guides

Imaging cell structure

Organelles play a critical role in cellular function, and the detection of specific organelles with organelle-selective stains, dyes, or specific antibodies is key in fluorescence imaging of cells and tissue. Organelle stains can be used as counterstains to help identify the location of specific proteins and targets of interest within the cell, while imaging antibodies against proteins associated with specific organelles can lead to a better understanding of cellular function. Our organelle stains include organelle-specific dyes and stains for live-cell or fixed-cell imaging as well as for flow cytometry.

Invitrogen offers an extensive portfolio of highly purified and specific fluorescently conjugated lectins. These lectins come in a variety of dyes including bright Alexa Fluor Dyes, Dylight Dyes, and other classic dyes, to provide bright and sharp images of cells for specific glycoprotein detection. Fluorescent conjugation allows you to easily localize and detect cell-surface or intracellular glycoproteins, making them a versatile primary detection approach for imaging flow or cytometry applications.

CellLight Fluorescent Protein Labeling

Invitrogen CellLight reagents provide the easiest way to label specific structures in live cells with fluorescent proteins. Simply add the reagent to your cells, incubate overnight, and you’re ready to image in the morning. These ready-to-use constructs express fluorescent fusion proteins targeted to specific intracellular structures. The fluorescent protein is introduced using a simple transfection step that doesn’t require molecular biology techniques to carry out—it works like a cell stain.
