Live/dead cell assays are ideally performed when cells are roughly 50% confluent to ensure cells are actively dividing and not inhibited by contact, allowing accurate measurement of proliferation, drug effects, or viability. Treatment at <50% confluency allows for proper evaluation of anti-proliferative effects without being affected by contact inhibition.

Why should 2D cell cultures be less than 50% confluent for this assay to work optimally?

Is it possible mantain alive organoids after using this kit?
1 answer-
As part of the protocol for CBA415, one must induce cytotoxicity. Therefore, we have not studied maintaining live organoids after using this kit. Please refer to the protocol for explanations of this kit's functions.

Could I know the exact concentration of each components(Calcein-AM, PI, Hoechst) ? I already understood your recommendations on the puroduct information sheet, but we need to know the exact concentration with units. ex.) uM or ug/ml
1 answer-
The exact concentrations of Calcein-AM, PI, and Hoechst are proprietary and cannot be disclosed.

Is it possible to use formaldehyde or formalin for fixing cells before utilizing this live/dead cell staining solution?
1 answer-
The use of this kit on formaldehyde or formalin fixed cells has not been assessed in our lab, and our literature survey has not provided a recommended protocol reference.
It's important to note that fixing cells with a crosslinker such as formalin or formaldehyde could potentially impact the results of this assay. The harsh conditions of crosslinking may lead to cell membrane damage and increased cell death. As this has not been tested in our lab, we highly recommend conducting a pilot experiment to confirm compatibility.

Could this product be used for live imaging for 72hours ?
1 answer-
Working solutions of the Propidium Iodide and the Hoechst 33342 are stable for at least 72 hours when refrigerated and protected from light. Calcein AM, once diluted to a working concentration in a aqueous diluent, will begin to degrade within several hours and storage is not recommended.

How long can I keep the dye solution for after I add the dyes in the PBS and media?
1 answer-
The dye solution for cell staining should be prepared just before use. Store at -20oC or below, and protect from light. The vials can be frozen and thawed up to 10 times. Before use, allow the vials to thaw to room temperature and centrifuge briefly.
