Biological Activity

Description

PbS/CdS QDs (PbS/CdSe QD) is a fluorescent probe that can be used for in vivo fluorescence imaging in the second near-infrared window^[1]^[2].

In Vivo

The 2nd-NIR fluorescence imaging at ca.1300 nm using the PbS/CdS QDs results in the highest signal to background ratio with a low blurring for in vivo imaging^[2].

MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.

Protocols

All Animals and Diseases

Bioluminescent/Fluorescent Imaging Xenograft
Bioluminescent and fluorescent imaging xenograft models use tumor cells engineered to express optical reporters so tumor engraftment, growth, dissemination, and treatment response can be monitored longitudinally in living animals and validated ex vivo. Bioluminescence imaging usually measures luciferase activity after substrate administration and is commonly used as a surrogate for viable reporter-expressing tumor burden, while fluorescence imaging measures reporter or probe emission and can support tumor localization, ex vivo confirmation, or complementary multimodal analysis.

Help & FAQs

How should lyophilized recombinant proteins be reconstituted and stored?

1. Before opening the cap, centrifuge the vial at 13000 rpm for 20-30 seconds. This step will ensure that any lyophilized powder that may have adhered to the cap or walls is collected at the bottom of the vial, minimizing the risk of product loss.
