  • Product overview

    Abcam's Annexin V-FITC Apoptosis Staining / Detection Kit is based on the observation that soon after initiating apoptosis, cells translocate the membrane phosphatidylserine (PS) from the inner face of the plasma membrane to the cell surface. Once on the cell surface, PS can be easily detected by staining with a fluorescent conjugate of Annexin V, a protein that has a high affinity for PS. The one-step staining procedure takes only 10 minutes. Detection can be analyzed by flow cytometry or by fluorescence microscopy. The kit can differentiate apoptosis vs necrosis when performing both Annexin V-FITC and PI staining.

    HeLa cells were harvested with trypsinization together with floating non-viable cells.  Cells were washed with PBS and  suspended in sodium citrate buffer 20 minutes prior to analysis. HeLa cells were treated with Mitoxantrone (MX) and MX +Imatinib for 48 hours. The samples were then stained with Annexin V-FITC Apoptosis Staining/Detection kit (ab14085). A FACSCalibur flow cytometer was used for cell cycle analysis.

Flow cytometery analysis of treated multiple myeloma cells

 Excellent Excellent 5/5 (Ease of Use)
Abreviews
Multiple myeloma cells were harvested by centrifugation after collecting the trypsinized cellls together with floating non-viable cells. Cells were washed with PBS and re-suspended in sodium citrate buffer 20 minutes prior to analysis. The cells were then treated with Mitoxantrone (MX) and MX +Imatinib for 24 hours. The samples were then stained with Annexin V-FITC Apoptosis Staining/Detection kit (ab14085). A FACSCalibur flow cytometer was used for cell cycle analysis.

Apoptosis in mouse cortical collecting duct cells

 Good Excellent 5/5 (Ease of Use)
Abreviews
We used the Annexin V-FITC apoptosis detection kit to determine minor levels of cell death (using both the Annexin V-FITC and PI) in mouse cortical collecting duct cellss (mCCDs). Using this kit, we were able to detect cell death in less than 5% of all cells using fluorescent microscopy. In the image provided, mCCD cells were incubated with serum free medium for 48h. The green label on the plasma membrane (Annexin V-FITC) and the absence of nuclear red (PI) staining indicates apoptosis rather than necrosis.

the protocol booklet for the Annexin v fit-c kit for flow cytometry doesnt mention a wash phase after antibody/PI addition. can i confirm that this is correct?? I.e, 5min incubation then straight into flow cytometer? to fix following this, is 4% PFA re...

Read More

Typically washing is not needed before analysing in the flow cytometer. However, if you wish to fix your cells, this can be done after incubating with Annexin V in binding buffer. The cells can then be washed in PBS and fixed in 2% PFA for 15 mins. Read More

U2OS cells were either treated with Staurosporine (0.5 uM) for 6 hours or left untreated in 6cm dishes. Cells were resuspended using PBS-EDTA and collected in a 15ml tube along with original culture media. Cells were centifuged at 1100rpm for 5 minutes and then resuspended in binding buffer before adding AnnexinV-FITC and PI as in protocol. Cells were incubated for 5 minutes at RT and then analysed.
Additional controls (graphs not shown): no stain, PI only, Annexin V only
Figure legend: U2OS cells were either A. Untreated, or B. Treated with 0.5uM Staurosporine for 6 hours. Percentage of Live (Q3), early apoptotic (Q4) and late apoptotic (Q2) populations are indicated.

Can be it offer a testing discount for each kits If the user would like to test the kits, Annexin V-FITC Apoptosis Detection Kit (ab14085) and In situ Direct DNA Fragmentation Assay Kit (ab66108), on yeast cells by IF?

Thank you for your email.

I discussed with my colleagues from the Scientific Support Team about the use of these kits in yeast and we agreed that the kit that is likely to work is the In situ Direct DNA Fragmentation Assay Kit (ab66108) but no...

Are the kits, Annexin V-FITC Apoptosis Detection Kit (ab14085) and In situ Direct DNA Fragmentation Assay Kit (ab66108), suitable for immunofluorosence application on yeasts? Do you have a protocol suggestion specific for yeasts applications?

Thank you for contacting us.

Unfortunately, these kits have been standardized for mammalian cells and the lab do not have the protocol suggestion of how to fit these to yeast cells, since they have never tried that.

Sorry I couldn't b...
