Description

Quantity: 20 x 50 μg
Unit Size: Each
• Upon entering the cell, intracellular esterases cleave the acetoxymethyl (AM) ester group, yielding the membrane-impermeable Calcein fluorescent dye
• Apoptotic and dead cells with compromised cell membranes do not retain Calcein
• Calcein is optimally excited at 495 nm and has a peak emission of 515 nm
• For flow cytometric analysis, it can be excited off the blue laser line (488 nm) and detected using filters for FITC/Alexa Fluor™ 488 (530/30)
• For multicolor flow cytometry, concentrations in the range of 5 to 20 nM are recommended to ensure that compensation can be performed successfully
• Co-staining with Annexin V or 7-AAD is recommended to allow the greatest resolution between live and dead/apoptotic cells
• If single-color analysis is desired, improved resolution between live and dead/apoptotic cells may be obtained by using either Calcein Blue AM (cat. 65-0855) or Calcein Violet 450 AM (cat. 65-0854)
• Calcein AM should be reconstituted in high-quality, freshly opened DMSO
• Once reconstituted, it should be stored at -20°C with dessicant and used within a short period of time (avoid freeze-thawing)
• Purity: >95% (determined by HPLC)
