How do you take calcein am?
To stain at 1 µM, add 10 µL of the Calcein AM solution that had been further diluted 1:10 in PBS to 390 µL cells, forming a final volume of 400 µL. If different cell volumes were used, add Calcein AM appropriately. Mix by gently flicking the tubes. 10.5 Incubate cells at 37°C protected from light.
Is calcein AM toxic?
Calcein, AM has been used for studies of enzymatic activity, cell membrane integrity, and long-term cell tracking due to its low cellular toxicity. It is important to note that for certain cell lines and experimental conditions, relatively high concentrations of Calcein, AM can be toxic to cells.
What is calcein staining?
Calcein AM is a cell-permeant dye that can be used to determine cell viability in most eukaryotic cells. In live cells the nonfluorescent calcein AM is converted to a green-fluorescent calcein after acetoxymethyl ester hydrolysis by intracellular esterases.
How do you dilute calcein?
2. Add 50 µL high-quality, anhydrous DMSO to one vial calcein AM to prepare a 1 mM stock solution. Add 10 µL of this stock solution to 190 µL DMSO to make a 50 µM working solution of calcein AM. Use this working solution within one day.
Is calcein cytotoxic?
Calcein/AM is a fluorescent dye that localises intracellularly after esterase-dependent cellular trapping and which has shown cytotoxic activity against various established human tumour cell lines at relatively low concentrations.
How do you dissolve calcein am?
Calcein AM, in contrast, is susceptible to hydrolysis. Therefore, it should be dissolved in organic solvents like DMSO with a concentration of approximately 10 mg/mL.
How do you make calcein solution?
Remove one 50 µg calcein AM from the freezer and allow to warm to room temperature. 2. Add 50 µL high-quality, anhydrous DMSO to one vial calcein AM, yielding a 1 mM stock solution. Once prepared, the DMSO stock solution should be used within a short time period for one series of experiments.
What is the function of the AM acetoxymethyl ester group on calcein?
The non-fluorescent acetomethoxy derivate of calcein (calcein AM, AM = acetoxymethyl) is used in biology as it can be transported through the cellular membrane into live cells, which makes it useful for testing of cell viability and for short-term labeling of cells.
Is calcein am light sensitive?
Calcein AM Dye is supplied at ambient temperature. Upon arrival store at -20°C. The product when stored as directed is stable for 1 year. light as Calcien AM dye is light sensitive.
Does calcein AM method assay the total cellular labile iron pool or only fraction of it?
Although lysosomes are known to be rich in iron (compare with Figure 3), quenching of the calcein-mediated fluorescence does not occur in lysosomes because calcein does not bind iron at lysosomal pH (compare with Figure 1), implying that the calcein-AM technique does not assay all intracellular, low-mass, labile iron.
What is calcein AM used for?
Calcein AM is a cell-permeant dye that can be used to determine cell viability in most eukaryotic cells.
What is the use of @calcein AM cell viability assay?
Calcein AM Cell Viability Assay can be easily adapted to various fluorescence setups, such as microplate assays, fluorescence microscope and flow cytometry. The assay is useful for various studies, such as cell viability, cell adhesion, chemotaxis, multidrug resistance, apoptosis and cytotoxicity.
How do you label cells with blue calcein?
Calcein AM, Calcein Violet AM, and Calcein Blue AM labeling dyes cross the cell membrane easily, selectively labeling live cells for analysis by flow cytometry or fluorescent microscopy; apoptotic and dead cells with compromised cell membranes do not retain calcein.
How to quantify Jurkat cells using calcein AM?
Figure 1. Calcein AM Quantification of Jurkat Cells – Jurkat cells were grown in RPMI supplemented with 10% Fetal Bovine Serum, washed with 1X Calcein AM DW Buffer, and counted using Trypan blue and a hemacytometer. Cells were serially diluted in a black-walled microplate and then incubated with 1 μM Calcein AM for 30 minutes at 37 °C under 5% CO
