Annexin V Assay Kit - 300 Tests gallery image 1 — Jurkat cells were treated as shown with staurosporine at 1 μM to induce apoptosis. The cells were then stained with annexin V FITC (ANNEX300F) and ReadiDrop™ propidium iodide (1351101). Apoptotic cells positive for annexin V can be seen in the bottom right quadrant and dead cells positive for both annexin and PI in the top right quadrant. Healthy cells are negative for both stains. Data acquired on the ZE5™ Cell Analyzer.

Annexin V:FITC Assay Kit used for cell cycle analysis of cells treated with Arsenic trioxide and *Macuna macrocarpa* extract by flow cytometry.
**Image caption:**
Annexin V-FITC/propidium iodide (PI) analyses of arsenic trioxide (ATO)- and/or crude methanolic extract of *Mucuna macrocarpa* (CMEMM)-treated cells. HL-60 (a) and Jurkat (b) cells (1 × 10⁵ cells/mL) were first treated with 5 mM N-acetyl cysteine (NAC), 50 μM butylated hydroxytoluene (BHT), or 40 μM α-tocopherol (VitE) or untreated, followed by treatment with 0.1% DMSO (CTL), 2.5 μM ATO, and/or 50 μg/mL CMEMM as indicated for 24 h. Quantitative percentages of apoptotic cells of ATO/CMEMM-treated cells were measured by flow cytometry. Data represent the result from one of three independent experiments.

ANNEX300F	F			300 Tests

This test employs the property of Annexin V to bind to the membrane phospholipid phosphatidylserine (PS) in the presence of Ca²⁺. PS is exposed at the cell surface during the early stages of apoptosis. Detection of PS is a very sensitive method for detecting cells entering apoptosis, at a time point considerably ahead of nuclear changes such as DNA degradation.

The conjugation protocol used to prepare this product has not changed the native phospholipid binding properties of Annexin V. This protocol is designed to measure apoptosis easily and quickly in a sample of suspended cells.

Where this product has not been tested for use in a particular technique this does not necessarily exclude its use in such procedures. Suggested working dilutions are given as a guide only. It is recommended that the user titrates the product for use in their own system using appropriate negative/positive controls.

Instructions For Use: 1) Dilute binding buffer 1:4 in distilled water (50ml binding buffer + 150ml distilled water).

2) Wash cells in PBS by gentle shaking or by pipetting up and down.

3) Resuspend cells in 200ul of pre-diluted binding buffer, adjusting to a cell density of 2-5 x 10⁵ cells/ml.

4) Add 5ul Annexin V:FITC to 195ul of the cell suspension prepared in step 3.

5) Mix and incubate for 10 minutes in the dark, at room temperature.

6) Wash cells in 200ul of pre-diluted binding buffer.

7) Resuspend cells in 190ul pre-diluted binding buffer.

8) Add 10ul of the Propidium Iodide solution.

9) Analyse by flow cytometry.

The flow cytometer is preferably set such that the Mean Fluorescence Intensity of the Annexin V negative population is between 1 and 10. Optimal parameter settings can be found using a positive control. For a positive control, incubate the cells with 3% formaldehyde in buffer during 30 minutes on ice. Wash away the formaldehyde and suspend the cells in cold binding buffer at 2-5 x 10⁵ cells/ml. Proceed with step 2 as described above.
