Exceptional tissue preservation

Published by Park et al. in Nature Biotechnology 2018, our SHIELD reagent (AKA GE38) safeguards endogenous fluorescence, protein antigenicity, nucleic acids, and overall tissue architecture against physical and chemical stressors. The SHIELD tissue preservation method also protects tissue during fluorescent protein imaging and antibody labeling across multiple rounds.

Compatible with:

GFP+ motor cortical neurons in whole mouse brain (left) and tdTomato+ in a mouse spinal cord cell-type (right)

Quick & easy tissue preservation protocol

Our streamlined protocol takes just 4-6 days, without the variability of tissue embedding via hydrogel or paraffin. Reagents are non-toxic and can be easily disposed of after use.
