Discover ClearLight Services 

ClearLight Biotechnologies provides tissue processing, imaging and analysis services to pharmaceutical, biotechnology and academic researchers. ClearLight utilizes the patent-protected CLARITY technology, licensed from Stanford University, Palo Alto, CA. The CLARITY technology allows clearing of animal and human tissue so that it can be analyzed with powerful 3D microscopes and AI software (under development). The images and analysis allow researchers to better understand the tissue and tumor microenvironment to facilitate discovery of new methods and drugs to treat disease.

3D IHC Services

ClearLight offers antibody-based immunostaining or labeling for many nucleic acids (RNA/DNA) to highlight specific structures in the clarified sample. Multiplexed immunofluorescence staining enables advanced Tru3D™ tissue analysis.

TRU 3D™ Tissue Analysis

After tissue clearing, animal and human tissue can be analyzed with powerful 3D microscopes and the company’s proprietary AI software (under development). This allows researchers to better understand the tissue and tumor microenvironment.

Submission Guidelines

The submitted sample must be pre-fixed in either

      • 4% paraformaldehyde (PFA) at 4°C or
      • 10% neutral buffered formalin (NBF) at 4°C for 24 hours.
        • Samples prepared with fixatives other than 4% PFA or 10% NBF have not been validated or already determined to interfere with our protocol.

The tissue must be noted:

      • Perfused or not Perfused
      • This is necessary for imaging purposes.

All submitted samples should clearly labeled.

      • A list of all supplied samples is preferred to confirm receipt of all samples.

Samples should be shipped in a sealed container or either PBS or TBS solution.

      • Samples that will be stored for prolonged periods (>1 week) of time prior to shipment should be stored in PBS+NaN3 (0.01%) at 4°C.

Shipped samples should be scheduled for delivery to ClearLight Biotechnologies Monday through Wednesday with a provided tracking number.

      • Please inform ClearLight Biotechnologies of the scheduled delivery and any additional delivery information.

It can be both, for a pilot it could be a new tissue or a new tissue and new antibodies. If at any point we have to optimize an antibody, then it becomes antibody feasibility.
