This product has not been tested for any specific application, including in vivo use. Suitability would have to be determined experimentally by the end user. Historical information suggests that a concentration of 0.5% Evans Blue in PBS at pH 7.4 has been used successfully in staining tissue sections. This concentration may also be effective starting point for in vivo applications. Please refer to available literature for additional information.

In vivo imaging of small animals offers several possibilities for studying normal and disease biology, but visualizing organs with single-cell resolution is challenging. We describe rotational side-view confocal endomicroscopy, which enables cellular imaging of gastrointestinal and respiratory tracts in mice

How to prepare a stock 1% solution using E2129, and is ther any guidance on its use?
1 answer-
A 0.5% solution of Evans Blue in PBS, pH 7.4. Product P3813 should be used as the PBS, which will serve as the stock solution. For use, 3-4 drops should be added to 100 mL of PBS P3813. This should be used as the final rinse with a 5-minute wash. After rinsing briefly, coverslip the sample.

How do I dilute 80% purity evans blue powder into a 2% solution with normal saline?
1 answer-
This product is soluble in water at 60 mg/mL. For typical laboratory staining applications, a 1X PBS solution is also commonly used. Solubility in normal saline has not been evaluated, but rates are expected to be similar. A 2% solution would be 20 mg/mL. The dye content is lot-specific and reported in the Certificate of Analysis.
