Lsrii facs machine

Manufactured by BD

The BD LSRII FACS machine is a flow cytometry instrument designed for cell analysis and sorting. It is capable of detecting and analyzing multiple parameters of individual cells or particles within a sample. The core function of the BD LSRII FACS machine is to provide high-performance flow cytometry capabilities for scientific and research applications.

Cell Viability and Cell Cycle Analysis

Check if the same lab product or an alternative is used in the 5 most similar protocols
The number of living cells was measured by trypan blue exclusion using Vi-Cell analyzer (Beckman Coulter). Cell-cycle distributions were performed on ethanol-fixed cells, stained with propidium iodide and analysed by flow cytometry. Flow cytometry data were acquired using CellQuest Pro (Becton Dickinson) software on the FACS LSRII machine (Becton Dickinson) and were analysed using ModfitLT (Verity) software.

RON Expression in T47D Cell Lines

Check if the same lab product or an alternative is used in the 5 most similar protocols
1 × 106 cells were harvested from T47D wildtype and T47D RON KO cell lines and washed in PBS. Cells were blocked and either paraformaldehyde fixed or stained live. Primary antibody staining was performed using 10 µg/ml of purified anti-RON antibodies. Cells were subsequently incubated with goat anti-mouse FITC-conjugated secondary antibodies (Invitrogen). FACS analysis was performed using FACS LSRII machine (Becton Dickinson). FlowJo (RRID:SCR_008520) (Tree Star Inc. USA) software was used for data analysis.

ATRA and TCP Induce Cell Differentiation

Check if the same lab product or an alternative is used in the 5 most similar protocols
AML cell lines were treated with ATRA (Sigma), and TCP (Sigma) for 4 days. Fluorescence-activated cell sorting (FACS) analysis of CD11b and CD86 expression were performed on 5×105 cells using aphycoerythrin-conjugated human CD11b-specific (BD Pharmingen, #555388) and Alexa fluor 700 CD86 (BD Pharmingen, #561124) mouse monoclonal antibody at a 1:5 dilution on a BD LSRII FACS machine (Becton Dickinson) with CellQuest software. We performed FACS analysis on live cells, which were sorted using a LIVE/DEAD fixable green dead cell stain (ThermoFisher).

Cell Cycle Analysis of ATRA and TCP

Check if the same lab product or an alternative is used in the 5 most similar protocols
Cell lines were plated and treated with the respective doses of ATRA, TCP, or ATRA-TCP in 96-well plates. After 4 days of treatment, cells were spun at 1500 RPM. Cells were fixed in 4% PFA following by permeabilization with 0.15% Triton-PBS and stained with DAPI. The percentage of cells in the different cell-cycle phases were determined with a BD LSRII FACS machine (Becton Dickinson) and analyzed using the FlowJo 10.6.1.

Flow Cytometric Analysis of Apoptosis in AML

Check if the same lab product or an alternative is used in the 5 most similar protocols
FACS analysis of CD11b (MAC-1) expression by AML cell lines and apoptosis analysis of patient samples after drug treatment were performed using an APC-conjugated human CD11b-specific mouse monoclonal antibody at a 1:10 dilution (Cat# 555388, BD Pharmingen) on a BD LSRII FACS machine (Becton Dickinson) with FACS Diva software. For analysis of apoptosis, the Annexin-V FITC apoptosis detection kit II (Cat# 556570, BD Pharmingen) was used according to the manufacturer’s instructions with Propidium Iodide (Cat# R37169, Invitrogen) at 1 μg/mL on Guava EasyCyte flow cytometer with InCyte software (Merck).

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.
