Calcein am pi double stain kit

Manufactured by Merck Group
Sourced in United States

The Calcein-AM/PI double stain kit is a laboratory product designed to assess cell viability and cytotoxicity. The kit contains Calcein-AM, a cell-permeant dye that is converted to a green fluorescent compound by live cells, and Propidium Iodide (PI), a dye that enters and stains the nuclei of dead or dying cells. This combination allows for the simultaneous detection of live and dead cells in a sample.

Cytotoxicity Evaluation of PTX@CAR-Exo

Check if the same lab product or an alternative is used in the 5 most similar protocols
The killing efficacy of PTX@CAR-Exo against MSLN-LLC cells was assessed using the Calcein-AM/PI Double Stain Kit (Sigma-Aldrich), which stains live and dead cells. Briefly, 1 × 105 MSLN-LLC cells per well were seeded in 12-well plates. Then, 100 μL of PBS, 100 μg of T-Exos, 100 μg of CAR-Exos, 100 μL of PBS containing 10 μg of PTX, 100 μg of T-Exos containing 10 μg of PTX, and 100 μg of CAR-Exos containing 10 μg of PTX were added to the Petri dishes. After incubation for 24 h, the live and dead cells stained with Calcein-AM/PI were observed under an inverted fluorescence microscope (Olympus). Then, quantification was performed using ImageJ software.

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
