T Cell based Intracellular Staining Assay Service

Creative Biolabs provides a direct and quantitative readout of T cell function, moving beyond simple cell counts to reveal what the cells are actively producing. Our service delivers precise and actionable insights into the immune response, which is crucial for vaccine and drug development. We can help you identify and characterize rare antigen-specific T cell populations and determine their cytokine, granzyme, and perforin profiles at a single-cell level. This detailed analysis is a cornerstone for determining the efficacy of a novel therapeutic or for monitoring disease progression.

Intracellular Staining Assay for Cancer Epitope Analysis

The intracellular staining approach is a prevailing method used to quantitatively measure the immune response-related proteins produced in cells, including cytokines and granzyme, and perforin, to assess cell responses to various stimuli. With a deep understanding of T cell immunity and successful experience in T cell phenotype and function study, Creative Biolabs offers T cell-based intracellular staining assay to study cancer epitope-induced specific T cell cytokine, granzyme, and perforin production, providing scientific information on the determination of targets for cancer immunotherapy.

Comparison of the ELISPOT Assay and Intracellular Staining Assay

ELISPOT Assay Intracellular Staining Assay
  • Analysis of pools of cancer epitope peptides
  • Recommended for the first round of large-scale screening
  • A small number of cells are needed
  • Monitor the T-cell response to a specific peptide or a small number of peptides
  • Providing comprehensive information on phenotype and function
  • Costs a larger number of cells

Highlights

Enhanced Detection

Our assay leverages a protein transport inhibitor to trap effector molecules like cytokines in the rough endoplasmic reticulum, ensuring they are localized and easy to detect with high sensitivity.

Direct Crude Sample Analysis

Our optimized protocols are designed to directly handle complex, unpurified samples such as PBMCs or splenocytes, streamlining your workflow by eliminating the need for upfront cell separation.

Service Features

Simultaneous Multi-Parameter Analysis

We can detect both intra- and extracellular protein markers simultaneously in every single target cell. This allows for a comprehensive, single-cell phenotypic and functional analysis.

Accuracy and Reliability

Our scientists are well-versed in the technical nuances of the assay, including potential artifacts, ensuring we deliver data that is not only robust but also scientifically accurate and reliable for your research.
