I want to use this kit for suspension cells. Protocol says to prepare a cell suspension with PBS at 1-10 x 10^5 cells/mL and then add 100uL of assay solution. Is it 100uL per mL of cell suspension?. Also, what is the concent of the original solutions?
1 回答-
200 microliters of cell suspension is mixed with 100 microliters of assay solution, and the mixture is incubated at 37 ºC.
Lot-specific concentrations of Solutions A and B are listed in the product's Certificate of Analysis.役に立ちましたか?

1 回答-
The original manufacturer of this kit recommends adding 100 microliters of assay solution to 200 microliters of the cell suspension. Unfortunately, this key bit of information is missing from the protocol. Each vial of Solution A contains a 1 mM solution of Calcein-AM in DMSO. The vial of Solution B contains a 1.5 mM solution of Propidium Iodide in pure water.

How many assays or tests can be conducted using one kit of PN: 04511-1KT-F?
1 回答-
The 04511 kit consists of 2 components, with reagent B being the limiting reagent, requiring just 300 microliters of reagent. To prepare the staining solution, 10 microliters of Reagent A and 5 microliters of Reagent B are mixed with 5 ml of PBS. Each test necessitates 100 microliters of the staining solution. With 5 microliters of Reagent B being sufficient for 50 tests, 300 microliters of Reagent B is adequate for 60 batches of the staining reagent, resulting in 3000 tests (50 x 60). Although the maximum number of specimens might not always be stained in practice, the kit theoretically should allow for 3000 tests.

Can the live/dead double staining kit be used on fixed cells?
1 回答-
The kit is not designed for use with just dead cells. When cells are fixed, it typically results in cell death for all cells. Consequently, if all the cells are dead, it is expected that the Calcein AM would not be able to enter the cells, as Calcein AM is not a fluorescent molecule. The available data sheet states, "While the cells are viable, the calcein generated from CalceinAM by esterase in a viable cell emits strong green fluorescence (excitation: 490 nm, emission: 515 nm)." Therefore, Calcein-AM only stains viable cells. If all the cells are dead, the only observed staining will be from the Propidium Iodide - which is the dead cell stain reagent in kit 04511.
If the cells are stained while viable, it is possible to image the cells after they have been fixed in paraformaldehyde or other fixatives. Although this is a common practice in some laboratories, It's suggested to consider a 10-minute fixation instead of 30 minutes, as fixing for 30 minutes may not be advisable.役に立ちましたか?
