Product Release: AURION R-Gent SE-Intense Silver Enhancement Reagent
The visualization of gold nanoparticles in light microscopy and macroscopic applications requires an enhancement system that delivers a high-contrast signal. Ease of use demands light insensitivity and negligible autonucleation, resulting in low background levels. AURION R-Gent SE-Intense is a two-component reagent specifically optimized to meet these requirements and takes the Immunogold Silver Staining method to the next level.

Aurion R-Gent SE-Intense: the successor to R-Gent SE-LM, featuring improved signal contrast, faster reaction times, and enhanced reproducibility.
Expert Guidance Through Our Workshops
We offer high-quality workshops for researchers worldwide who wish to gain a solid understanding of both the theoretical and practical aspects of immunogold/silver staining techniques.
Participants bring their own primary antibodies and ready-to-use reagents, allowing them to learn, practice, and evaluate labeling procedures on-site under expert guidance. For more information about our workshops, visit the IGSS Workshops section under Sharing Our Knowledge or check our news page for upcoming workshops .
We are always happy to discuss which immunodetection methods are best suited to your application. Please contact one of our experts for personalized advice.
