Detecting Cell Apoptosis on Tissue Slides

Apoptosis, or programmed cell death, is a physiological process in which individual cells are set to die without harming their environment. It involves a cascade of complex and tightly regulated cellular events. Detecting apoptosis on tissue slides, involves either detecting the molecular participants of these events, or the morphological changes that occur on the cellular…

In Situ Zymography: Let’s Catch that Enzyme in Action!

In situ zymography (ISZ) is the best choice to study proteases. Proteases are a challenge to study as proteases are extremely potent enzymes. As such, they need to be controlled at multiple levels to prevent them from being unleashed and making a cellular mess. Regulation of their activity occurs at virtually all levels: transcriptional control,…
