rAAV Rainbow Combo™ ()

Introducing the Brain Case “Rainbow Flexible Combo Program”
-Flexible Multi-Virus Ordering for Modern Neuroscience Research

To better support the increasingly diverse needs of modern neuroscience research, Brain Case is launching the new “Rainbow Flexible Combo Program” — a flexible ordering initiative designed to provide researchers with greater experimental freedom and improved cost efficiency.

This program brings together multiple widely used neuroscience toolsets, including:

-Optogenetics
-Chemogenetics
-Calcium Imaging
-Neurotransmitter Sensors

Researchers can freely mix and match five different viral tools at 20 μL each across categories to build customized combinations tailored to their own experimental strategies.

This new format is especially suitable for:

-Multi-virus experimental designs
-Neural circuit screening studies
-Parallel testing of different functional elements
-Multi-region or projection-specific experiments
-Combined manipulation and recording strategies

By lowering the entry barrier for combinational experiments while maintaining experimental versatility, the Rainbow Flexible Combo Program helps researchers achieve more flexible study designs with optimized cost performance, providing the neuroscience community with accessible, research-oriented viral vector solutions.

🧪 Viral Vector Combo Pack — $794
Choose from three curated combo options, each containing 5x20 ul viral vectors
