Why Early Adopter?

  • Competitive edge in whole-organ labeling and specialized technical support from our scientists


  • Customized protocol development for your specific sample types and labels of interest

Rapid Immunostaining
with Unparalleled Uniformity

Fast, Easy, and Reliable

Speed: Order of magnitude faster than passive labeling (1-3 days compared to weeks or months)

Easy: Plug-and-play
Reliable: Prevents tissue damage with Stochastic Electrotransport technology (Kim, PNAS, 2015). Our nanoporous membranes (patent-pending) eliminate tissue contamination and probe loss.

Complete and Uniform Labeling

Complete: Full staining of organ-scale samples (e.g., mouse brain)

Uniform: Unparalleled signal uniformity throughout the sample

Cost Savings by Avoiding Target Saturation

Antibody savings: Complete and cost-effective labeling with a small amount of antibody by preventing antibody depletion

SmartLabel is compatible with many clearing techniques including:
  • CLARITY (Chung, Nature, 2013)
  • SWITCH (Murray, Cell, 2015)
  • MAP (Ku, Nature Biotechnology, 2016)

Anti-GFAP Staining in CA1 Hoppocampus 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 2 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).
