Intratumoral Treg Assay Service
Creative Biolabs specializes in providing innovative solutions for cancer research and therapy development. We provide cutting-edge intratumoral Treg Assay Service that enables comprehensive analysis and characterization of intratumoral T regulatory cells (Tregs). By utilizing advanced techniques and state-of-the-art technologies, our service provides valuable insights into the role of Tregs in the tumor microenvironment, aiding in the development of novel immunotherapeutic strategies.
FoxP3⁺ T Regulatory Cells Analysis
FoxP3, a master regulator of Treg function, serves as a reliable marker for the identification and quantification of Tregs. The assay employs state-of-the-art techniques, including flow cytometry, immunohistochemistry, and molecular biology assays, to accurately assess the presence and functional status of intratumoral Tregs. By employing a multi-parametric approach, Creative Biolabs can provide detailed information regarding the frequency, phenotype, and functional characteristics of intratumoral Tregs, facilitating a comprehensive understanding of their role in tumor progression and immune evasion.

Tumor-Infiltrating Treg Phenotyping Service
Our tumor-infiltrating Treg phenotyping service follows a well-defined workflow designed to ensure accurate and reliable results. The workflow can be divided into the following key steps:
Sample Preparation
We start by collecting tumor samples, either through surgical resection or biopsy, ensuring proper preservation and handling to maintain sample integrity. Our experienced team then processes the samples to obtain single-cell suspensions, optimizing cell viability for subsequent analysis.
Treg Cell Enrichment
To isolate tumor-infiltrating Treg cells, we employ state-of-the-art cell sorting technologies. By utilizing specific markers, such as FOXP3, CD25, and CD127, we selectively enrich Treg cells from the heterogeneous tumor-infiltrating lymphocyte population.
Phenotypic Profiling
Once the Treg cells are isolated, we employ a range of cutting-edge techniques for their phenotypic characterization. Flow cytometry is utilized to analyze surface markers, such as CD4, CD8, and various immune checkpoint molecules.
Functional Assays
We perform functional assays to evaluate the immunosuppressive capabilities of tumor-infiltrating Treg cells. These assays include suppression assays, cytokine profiling, and proliferation assays, which provide insights into the regulatory mechanisms employed by Treg cells to inhibit the effector functions of other immune cells.
