Live and metabolically active cells are labeled with Calcein, dead cells are labeled with PI, and total number of cells is determined by Hoechst. CSK-V0006-1 replaces the discontinued CSK-V0001-1 offering.
Calcein am staining
Did you know?
Calcein, also known as fluorexon, fluorescein complex, is a fluorescent dye with excitation and emission wavelengths of 495/515 nm, respectively, and has the appearance of orange crystals. Calcein self-quenches at concentrations above 70mM and is commonly used as an indicator of lipid vesicle leakage. It is also used traditionally as a complexometric indicator for titration of calcium ions with E… WebIHC staining for CD31 and PAS staining revealed VM, which was mostly detected in specimens with high TJP1 expression (Fig. 1 D). We also compared the expression levels within individual specimens and found that TJP1 expression was positively correlated with VM, with 50 (57%) out of 74 and 3 (4%) out of 13 specimens showing high expression of …
WebCalcein AM is a fluorogenic esterase substrate and should only be used on live cells to determine cell viability. Does calcein AM stain bacteria? A mixed population of Live/Dead Bacillus subtilis were stained with calcein AM and propidium iodide (Cat No. 17517 ). WebDilute the 1% crystal violet stain to 0.2% using 1X PBS. Calcein AM stock preparation Quickly centrifuge the microcentrifuge tube to pellet the powder before opening the tube. Add 25 µL of sterile DMSO to make a 2 mM stock solution, and pipette up and down gently to mix the solution. Store the calcein AM stock in single-use aliquots at –20°C.
WebCalcein AM is a cell-permeant dye that can be used to determine cell viability in most eukaryotic cells. In live cells the non-fluorescent calcein AM is converted to green-fluorescent calcein, after acetoxymethyl ester hydrolysis by intracellular esterases.
