Epi-Illumination Fluorescence and Reflection-Contrast Microscopy

This article discusses the development of epi-illumination and reflection contrast for fluorescence microscopy concerning life-science applications. Much was done by the Ploem research group…

Molecular structure of the green fluorescent protein (GFP)

Introduction to Fluorescent Proteins

Overview of fluorescent proteins (FPs) from, red (RFP) to green (GFP) and blue (BFP), with a table showing their relevant spectral characteristics.

Differential Interference Contrast (DIC) Microscopy

This article demonstrates how differential interference contrast (DIC) can be actually better than brightfield illumination when using microscopy to image unstained biological specimens.

Phase Contrast and Microscopy

This article explains phase contrast, an optical microscopy technique, which reveals fine details of unstained, transparent specimens that are difficult to see with common brightfield illumination.

Immersion Objectives

How an immersion objective, which has a liquid medium between it and the specimen being observed, helps increase the numerical aperture and microscope resolution is explained in this article.

Precise Spatial Proteomic Information in Tissues

Despite the availability of imaging-based and mass-spectrometry-based methods for spatial proteomics, a key challenge remains connecting images with single-cell-resolution protein abundance…

Studying Wound Healing of Smooth Muscle Cells

This article discusses how wound healing of cultured smooth muscle cells (SMCs) in multiwell plates can be reliably studied over time with less effort using a specially configured Leica inverted…

How to Prepare your Specimen for Immunofluorescence Microscopy

Immunofluorescence (IF) is a powerful method for visualizing intracellular processes, conditions and structures. IF preparations can be analyzed by various microscopy techniques (e.g. CLSM,…
