3D Tissue Clearing Reagent

Updated: 2026-07-23

Overview

3D Clear Reagent is a chemical solution designed to render biological tissues transparent, enabling high-resolution 3D imaging. It is widely used in neuroscience, histology, and developmental biology to study complex tissue architectures without physical sectioning. The reagent's optical properties minimize light scattering, allowing deeper penetration of imaging techniques like light-sheet and confocal microscopy. Developed as an alternative to traditional clearing methods, 3D Clear Reagent offers faster processing times and better preservation of fluorescent labels. Its formulation is optimized for compatibility with a wide range of staining protocols, making it a versatile tool for researchers.

Physical and Chemical Properties

3D Clear Reagent is a clear, colorless liquid with a high refractive index (typically 1.45-1.55), which matches closely with biological tissues to reduce optical distortions. Its low viscosity ensures efficient penetration into dense tissues, while its chemical stability prevents degradation of cellular structures during prolonged clearing processes. The reagent is miscible with water and common organic solvents, facilitating easy integration into existing laboratory workflows. Its biocompatibility minimizes tissue damage, preserving antigenicity for immunohistochemistry. Density ranges from 1.1 to 1.3 g/cm³, depending on the specific formulation.

Main Applications

Primary applications include whole-organ imaging in neuroscience, where the reagent clarifies brain tissues for connectome mapping. It is also used in cancer research to visualize tumor microenvironments in 3D and in developmental biology to track embryonic structures. In clinical settings, 3D Clear Reagent aids in pathology by enabling volumetric analysis of biopsy samples. Its compatibility with fluorescent proteins and dyes supports multiplexed imaging, allowing simultaneous visualization of multiple biomarkers. Advanced techniques like CLARITY and iDISCO rely on similar reagents for tissue transparency.

Safety and Storage

While 3D Clear Reagent is generally low-toxicity, standard laboratory precautions apply: use nitrile gloves, safety goggles, and work in a fume hood if handling large volumes. Avoid prolonged skin contact, as some formulations may cause mild irritation. Store the reagent in sealed, light-proof containers at room temperature (15-25°C). Exposure to moisture or extreme temperatures can alter its properties. Shelf life is typically 12-24 months when stored properly. Dispose of waste according to local regulations for organic solvents.

B2B Procurement Guide

When sourcing 3D Clear Reagent, prioritize suppliers with ISO 13485 or GMP certification for consistent quality. Request technical datasheets detailing refractive index, viscosity, and batch-specific performance data. For large-scale purchases, negotiate bulk discounts but verify storage capacity to prevent degradation. Key selection criteria include compatibility with your imaging system (e.g., refractive index matching), processing time requirements, and preservation of fluorescence. Some manufacturers offer customized formulations for specific tissue types or imaging modalities. Lead times vary; specialty reagents may require 4-8 weeks for delivery.
