简介：
Overview
This protocol enables the simultaneous measurement of calcium responses in primary T-cells while assessing their subset and surface phenotype. It leverages full spectrum flow cytometry to analyze T-cell receptor stimulation effectively.
Key Study Components
Area of Science
- Immunology
- Cell Biology
- Flow Cytometry
Background
- Calcium influx is a critical indicator of T-cell signaling.
- Traditional methods require isolation of specific cell subsets for analysis.
- This protocol streamlines the process by allowing simultaneous measurements.
- Indo-1 AM is used to detect calcium levels in T-cells.
Purpose of Study
- To analyze T-cell responses to receptor stimulation.
