Fast, Easy, & Efficient

Labels large, intact samples such as rodent organs an order of magnitude faster than with passive labeling (≤ 24 hours vs. weeks to months).

Turnkey operation: simply load the buffers, your sample, and probes. Performs 2 distinct labeling experiments simultaneously thanks to its dual chamber design

Uses a small amount of antibody (as little as ~3 µg) to label tissues the size of a whole mouse brain.

Prevents tissue damage with stochastic electrotransport technology. Our nanoporous membranes (patent pending) eliminate tissue contamination and probe loss.

Complete & Uniform

Achieves unparalleled uniformity of signal intensity from surface to core using LifeCanvas’s advanced eFLASH protocol.

Combines rapid, stochastic electrotransport-mediated infiltration of probes into tissue with the SWITCH technique of controlling probe binding kinetics.


Prevents antibody depletion caused by excessive binding to superficial tissue sites and ensures the sample’s center is well-labeled. 


Anti-GFAP Staining in CA1 Hippocampus of 2-mm Thick Section of Mouse Brain

Volume rendering of anti-GFAP staining in a 2-mm thick section of mouse brain, with signal in CA1 hippocampus most prominent. Labeling achieved in 2 days using antibody electrophoresis performed by SmartLabel. Cleared with SmartClear II Pro (<1 day), refractive index-matched with EasyIndex, and light-sheet imaged with SmartSPIM (<4 minutes acquisition time with 2-µm z-step and 1.8 µm/pixel XY; 2×2 tile using a 3.6x, 0.2 NA objective).

SmartLabel: Rapid Immunostaining with Unparalleled Uniformity

SmartLabel, the world’s first active labeling device, combines SWITCH and stochastic electrotransport technologies to quickly and uniformly label whole tissue samples in a fraction of the time needed for passive labeling. Stain an entire mouse brain or rat hemisphere in 24 hours or less and avoid the time-intensive, destructive sectioning and tedious image reconstruction of traditional histology.
