Topographic Analysis of Firing Pin Impressions on Cartridge Cases

The analysis of fired cartridges for primer cup morphology and flattening and firing pin impression (crater) depth using topographic data is discussed in this article. Topographical analysis of the…

Intraoperative OCT-Assisted Gene Therapy

Gene augmentation therapy is a method of ocular gene transfer for autosomal recessive or X-linked retinal dystrophies when there is insufficient functional protein manifesting as genetic disease.…

How does an Automated Rating Solution for Steel Inclusions Work?

The rating of non-metallic inclusions (NMIs) to determine steel quality is critical for many industrial applications. For an efficient and cost-effective steel quality evaluation, an automated NMI…
Mouse retina was fixed and stained by following reagents: anti-CD31 antibody (green): Endothelia cells, IsoB4 (red): Blood vessels, and microglia anti-GFAP antibody (blue): Astrocytes Sample courtesy by Jeremy Burton, PhD and Jiyeon Lee, PhD, Genentech Inc., South San Francisco, USA. Imaged by Olga Davydenko, PhD (Leica). Imaged with a THUNDER Imager 3D Cell Culture.

An Introduction to Computational Clearing

Many software packages include background subtraction algorithms to enhance the contrast of features in the image by reducing background noise. The most common methods used to remove background noise…

Challenges Faced When Manually Rating Non-Metallic Inclusions (NMIs) to Determine Steel Quality

Rapid, accurate, and reliable rating of non-metallic inclusions (NMIs) is instrumental for the determination of steel quality. This article describes the challenges that arise from manual NMI rating,…

Expanding the Frontiers of Confocal Live Cell Imaging

Here we explore how STELLARIS unlocks the full power and potential of live cell studies by overcoming many common limitations and fully integrating fluorescence lifetime-based information to add a new…

How to Uncover Hidden Dimensions in Research with Lifetime Imaging

Learn how fluorescence lifetime imaging adds information depth to your confocal experiments and reveals novel insights that are difficult or impossible to discover using conventional intensity-based…
Fluorescence microscopy image on the left with no distinction between the fluorescent signal and background autofluorescence. FLIM was used in the image on the right to differentiate autofluorescence in chloroplasts (blue) from the desired fluorescent signal from the cell membrane (green).

Learn how to Remove Autofluorescence from your Confocal Images

Autofluorescence can significantly reduce what you can see in a confocal experiment. This article explores causes of autofluorescence as well as different ways to remove it, from simple media fixes to…

Bridging Structure and Dynamics at the Nanoscale through Optogenetics and Electrical Stimulation

Nanoscale ultrastructural information is typically obtained by means of static imaging of a fixed and processed specimen. However, this is only a snapshot of one moment within a dynamic system in…
