Calcein am pi kit

Manufactured by Solarbio
Sourced in China

The Calcein-AM/PI kit is a fluorescence-based assay designed to detect and distinguish between live and dead cells. Calcein-AM is a cell-permeant dye that is converted to a green fluorescent compound by esterases in live cells, while propidium iodide (PI) is a red fluorescent dye that can only enter cells with compromised membranes, staining the nuclei of dead or dying cells. This kit allows for the simultaneous visualization and quantification of live and dead cells.

Live/Dead Cell Staining Assay

Check if the same lab product or an alternative is used in the 5 most similar protocols
Live/dead staining assay was performed using a Calcein-AM/PI kit (CA1630, Solarbio, Beijing, China). B16-F10 cells were collected, and the supernatant was removed. Cell suspensions were prepared with a density of 1×105 cells/mL. Staining working solution (100 µL) was added to 200 µL cell suspensions, and the mixture was incubated at 37°C for 15 min. Then, the cells were observed under a confocal microscope (LEICA TCS SPE, Leica, Dresden, Germany).

To detect the presence of CD133+ and CD44+ cells, anti-human/mouse CD44 (F1104401, 1 : 20, MULTISCIENCES, Hangzhou, China), fluorescein isothiocyanate (FITC) (MULTISCIENCES), and FITC anti-human CD133 antibody (567908, 1 : 20, BD Biosciences, Franklin Lakes, NJ, USA) were used to label the cells. Then, the cells were detected via flow cytometry (CytoFLEX, BECKMAN, Brea, CA, USA). Furthermore, CCSCs were treated with 1 μM oxaliplatin (#HY-17371, MedChemExpress, Monmouth Junction, NJ, USA) and 100 nM VD. A living/dead cell double staining assay was performed using the Calcein-AM/PI Kit (Solarbio, Beijing, China), according to the manufacturer's instructions. Dead cells were stained with PI, and their percentages were revealed when detected using flow cytometry.

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.
