Data Acquisition in Immunology
Sample Preparation
You need to start with good sample preparation to get reliable flow cytometry results. High cell viability is key for accurate data. Always create a single-cell suspension. This step helps you avoid clumps that can block the cytometer. Use mechanical or enzymatic methods to break down tissues or adherent cells. These techniques help you get more live cells for your analysis.
It is essential that the viability of the cell population under examination be known, regardless of the sample preparation method used. Viability assays using impermeant DNA-binding dyes can assess the integrity of the plasma membrane.
To reduce background noise, use proper blocking, washing, and fixation steps. Titrate your antibodies to find the best concentration. This practice increases specificity and lowers unwanted signals. After staining, wash your samples well to remove extra fluorescent reagents. Include viability dyes to help you exclude dead cells, which can stick to antibodies and affect your results.
Collection Best Practices
You can improve your data quality by following best practices during collection. Design your staining panel carefully. This step helps you separate different cell types and markers. Always check your data files by hand to remove technical errors and low-quality samples.
| Best Practice | Description |
|---|---|
| Well-designed staining panel | A crucial requirement for high-quality spectral flow cytometry data. |
| Manual data check | Essential to clean files and exclude technical artifacts and low-quality samples. |
| Unmixing of raw data | Use single-stain controls for accurate unmixing; Cytek’s SpectroFlo® software is recommended. |
| N x N plot | Helps identify unmixing issues by plotting all markers against each other. |
| Manual gating | Necessary for quality control, including time gate and exclusion of doublets and dead cells. |
Use single-stain controls for unmixing and plot all markers against each other to spot problems. Manual gating helps you remove doublets and dead cells, making your results more accurate.
Data Management
You need a strong system to store and organize your flow cytometry data. Many labs use Laboratory Information Management Systems (LIMS), ImmPort, or immune epitope databases. These systems help you keep your data safe and easy to find.
- Laboratory Information Management Systems (LIMS)
- ImmPort database
- Immune epitope database
- T1DBase database
Good data management protects your data’s integrity and allows for long-term storage. You can also access your data remotely for analysis. Always capture detailed metadata, such as creation date and storage details. Track your quality control steps and document any changes you make to the data. This practice supports reproducibility and makes it easier to trace your analysis steps.
Analysis with Prism
Importing Data
You start your analysis in prism flow cytometry by importing your cytometry data. Prism supports many file types, including FCS files from most cytometers. You can drag and drop files or use the import wizard. This step helps you organize your data for further analysis. Always check that your files load correctly. If you see errors, review your file format or update your software.
Tip: Keep your data organized in folders by experiment date or sample type. This makes it easier to find your files during data analysis.
Gating Strategies
Gating is a key part of cytometry analysis. You use gates to select specific cell populations from your data. Prism flow cytometry offers both manual and automated gating. Automated gating algorithms in Prism show high accuracy and reproducibility for many cell types. For example, automated gating for total monocytes matches manual results very closely, with a correlation above 0.99 and an F1 score of 0.99. For nonclassical monocytes, the correlation is lower (0.83), showing that some populations are harder to define. CD56++ NK cells also show high reproducibility with both methods.
You can use different gating strategies to identify immune cell populations. The table below shows common cell types and how you can gate them in your analysis:
| Cell Type | Gating Strategy Description |
|---|---|
| T cells | Identified based on CD11b and CD64 expression. |
| B cells | Labeled with specific markers for identification. |
| NK cells | Distinguishable as CD11bint CD64-. |
| Neutrophils | Identified within specific gates based on scatter properties. |
| Eosinophils | Distinguished from macrophages and DC using CD24 and CD64. |
| Inflammatory Monocytes (iMono) | Ly6Chi CD11c- inflammatory monocytes. |
| Resident Monocytes (rMono) | Ly6C- CD11c+ resident monocytes. |
| Alveolar Macrophages (AMФ) | Identified within the IA/IE+ or SCChi cells. |
| Interstitial Macrophages (iMФ) | Distinction based on CD24 and CD64 expression. |
| CD11b- Dendritic Cells (DC) | Identified as IA/IE+ CD11b- DC. |
| CD11b+ Dendritic Cells (DC) | Identified as IA/IE+ CD11b+ DC. |
| Myeloid Leukocytes (R5) | Subdivided based on side scatter vs. MHC class II expression. |
| Gates R1-R9 | Contour plots used for identification of major immune cell populations. |
You can use contour plots to help you identify major immune cell populations. These plots show the density of events and help you set your gates more accurately.
