Pe annexin 5 apoptosis kit 1

Manufactured by BD
Sourced in United States

The PE Annexin V Apoptosis Kit I is a laboratory equipment product designed for the detection and quantification of apoptosis. It utilizes the binding properties of Annexin V, a protein that has a high affinity for phosphatidylserine, which is exposed on the cell surface during apoptosis. The kit provides the necessary reagents to perform this analysis.

5 protocols using pe annexin 5 apoptosis kit 1

1

Apoptosis in Adipocyte Co-culture

Check if the same lab product or an alternative is used in the 5 most similar protocols
Cumulus cells (CCs) were seeded in six-well plate (105 cells/well) and cultured for 12 h. Cells were harvested 12 h after being co-cultured with pre-adipocytes/mature adipocytes or extracellular vesicles derived from pre-adipocytes/mature adipocytes. All the cells after treatment were collected and were detected by flow cytometry with the PE/Annexin-V Apoptosis Kit I (BD Biosciences, USA).

Flow Cytometry Analysis of Cell Markers

Check if the same lab product or an alternative is used in the 5 most similar protocols
For flow cytometry measuring cell surface markers, differentiated CD34+ cells were incubated for 30 minutes with PE-Cy5-conjugated anti-CD71 (BD Biosciences PharMingen). For flow cytometry in DBA patient-derived CD34+ cells, we followed the protocols described in Doulatov et al.(58 (link)). For Annexin V/7-AAD staining, PE Annexin V Apoptosis Kit I (BD Biosciences PharMingen) was used, following manufacturer instructions.

Cell Viability Assessment in Microfluidics

Check if the same lab product or an alternative is used in the 5 most similar protocols
We performed short-term (0 h) and long-term (24 and 48 h) viability experiments on cells collected from the target outlet. The PE Annexin V Apoptosis Kit I (BD Biosciences, United States) was used to detect short-term cell viability. The kit contains two dyes, PE Annexin V and 7-Amino-Actinomycin (7-AAD), which can detect early apoptotic cells (PE Annexin positive, 7-AAD negative), late apoptotic cells or dead cells (PE Annexin positive and 7-AAD positive), and viable cells (PE Annexin and 7-AAD negative). Cell viability was calculated as the ratio of the number of viable cells to the total number of cells. For the long-term cell viability, the collected cells were cultured in 24 wells (Corning, United States) for further observation of the cell viability and morphology after going through the chip at 24 and 48 h. All cell viability tests were designed with the control groups.

Multiparameter Flow Cytometry Analysis

Check if the same lab product or an alternative is used in the 5 most similar protocols
All samples were analyzed on BD FACSCanto II or BD LSRFortessa cytometers, and data were analyzed using FlowJo software (FlowJo, LLC). The following antibodies/clones were used for cell analysis: CD3ε (clone 145-2C11, FITC, BioLegend; clone 145-2C11, APC, BioLegend), CD4 (clone RM4.5, FITC, BioLegend; clone RM4.5, eFluor 450, eBioscience; clone RM4.5, PerCP-Cy5.5, eBioscience), CD5 (clone 53-7.3, FITC, BD Biosciences), CD8α (clone 53-6.7, APC, BD Biosciences), CD24 (clone MI/69, FITC, BioLegend), CD25 (clone PC61, PE, Biolegend), CD44 (clone IM7, FITC, BioLegend), CD45.1/Ly5.1 (clone A20, eFluor 450, eBioscience), CD62L (clone MEL-14, PE, BioLegend), CD69 (clone H1.2F3, PE-Cy7, BioLegend), CD90.1/Thy1.1 (clone OX-7, PE, BioLegend), CTLA-4 (clone UC10-4B9, APC, eBioscience), Foxp3 (clone FJK-16S, APC, eBioscience), PD-1 (clone RMPI-30, PE-Cy7, BioLegend), TCRβ (clone H57-597, PerCP-Cy5.5, BioLegend; clone H57-597, FITC, BD Biosciences).
For measurement of apoptosis, the PE Annexin V Apoptosis Kit I (BD Pharmingen) was used according to manufacturer’s instructions.

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
