Product Description

The Apoptosis and Necrosis  Quantitation Kit Plus provides a convenient assay for quantifying apoptotic (green) and necrotic (red) cells within the same cell population by flow cytometry or fluorescence microscopy.

Apoptosis and necrosis are two major processes by which cells die. Apoptosis is an active, genetically regulated disassembly of the cell from within. During apoptosis, phosphatidylserine (PS) is translocated from the inner to the outer leaflet of the plasma membrane for phagocytic cell recognition. The human anticoagulant Annexin V is a 35 kDa, Ca2 -dependent phospholipid-binding protein with high affinity for PS. Annexin V labeled with CF®488A stains apoptotic cells green by binding to PS exposed on the cell surface. CF®488A is spectrally similar to fluorescein (FITC), with much brighter and more photostable fluorescence.

Necrosis normally results from severe cellular insult. Both internal organelle and plasma membrane integrity are lost, resulting in the release of cellular contents into the surrounding environment. Ethidium homodimer III (EthD-III) is a highly positively charged nucleic acid probe, which is impermeant to live cells, but stains cells with compromised membrane integrity with red fluorescence. EthD-III is a superior alternative to propidium iodide (PI) or ethidium homodimer I because of its significantly higher affinity for DNA and higher fluorescence quantum yield. The Apoptosis & Necrosis Quantitation Kit Plus provides a convenient assay for quantifying apoptotic (green) and necrotic (red) cells within the same cell population by flow cytometry or fluorescence microscopy.

Features:

  • Simple: Simultaneous detection of both apoptotic and necrotic cells in a single assay
  • Fast: A single 15-30 min staining step
  • Sensitive: CF®488A Annexin V is brighter and more photostable than FITC Annexin V, while EthD-III is a superior alternative to both PI and EthD-I for staining necrotic cells.

Kit Components:

  • CF®488A Annexin V
  • Ethidium Homodimer III (EthD-III)
  • 5X binding buffer

Spectral properties (Ex/Em):

  • CF®488A Annexin V: 490/515 nm
  • Ethidium homodimer III (EthD-III) (with DNA): 522/593 nm (EthD-III also has a large absorption peak at 279 nm)

    Staurosporine

    Staurosporine is a potent and cell-permeable inhibitor of a wide variety of protein kinases (1,2) including protein kinase C (IC50 = 0.7 nM), protein kinase A (IC50 = 7 nM), and protein kinase G (IC50 = 8.5 nM). Staurosporine induces apoptosis in human neuroblastoma cells and chick embryonic neurons (3,4).

    Live-or-Dye™ Fixable Viability Staining Kits

    Live-or-Dye™ Fixable Viability Staining Kits are designed for discrimination between live and dead cells during flow cytometry. Live/dead stains are useful probes to include when analyzing cell surface protein expression by flow cytometry, because they allow intracellular fluorescence signal from dead cells with permeable plasma membranes to be excluded from analysis.
