Eliminating Electrostatic Interference in Laser Microdissection

Electrostatic charge in laser microdissection (LMD) causes two critical failures: samples stick to charged surfaces and are lost, or samples fly into adjacent wells and cause cross-contamination. We…

History, Developments and Trends of Microscopy in Cancer Research

Cancer is a global disease, with 18 million new cases diagnosed and 10 million cancer-related deaths worldwide in 2020. This burden is set to increase, with a projected increase in cases of ~55% by…

A Guide to Fluorescence Microscopy

Fluorescence microscopy uses the ability of fluorophores, dyes, or fluorescent proteins to emit light of a specific wavelength after being excited with light of a shorter wavelength. Biomolecules can…
Foraminifera (Ammonia confertitesta) labeled with membrane-permeable calcein, high-pressure frozen in salt water using EM ICE. The sample was cryo-planed and targeted with the M205 on the Cryo-Fluo Enuity, then transferred under cryo conditions to the Cryo-Stellaris for widefield and confocal imaging, revealing details of the staining pattern.
