Fluorescence Photoactivation Localization Microscopy (FPALM) Imaging Service

Introduction

Fluorescence Photoactivation Localization Microscopy (FPALM) is a cutting-edge imaging technique that has revolutionized the realm of microscopy. This method transcends the classical diffraction limit, enabling researchers to visualize spatial distributions of a vast number of fluorescent molecules with unparalleled precision. By harnessing the power of photoactivatable fluorescent probes, FPALM offers a resolution ranging from 10 to 40 nanometers, providing a detailed insight into molecular structures and interactions.
