Precision analysis of a whole blood T cell subset immunophenotyping assay

Precision analysis of a whole blood T cell subset immunophenotyping assay

Background The Cancer Immunotherapy Trials Network has initiated several clinical trials utilizing T cell growth factors such as IL-15 and IL-7. In support of these trials, we have developed and conducted precision testing of a 12-color flow cytometric assay to characterize the surface markers present on T cells in fresh whole blood and among cryopreserved peripheral blood mononuclear cells (PB...

Optimizing a multicolor immunophenotyping assay.

Flow cytometry-based immunophenotyping assays have become increasingly multiparametric, concomitantly analyzing multiple cellular parameters. To maximize the quality of the information obtained, antibody conjugate panels need to be developed with care, including requisite controls at every step. Such an optimization procedure for multicolor immunophenotyping assays is time consuming, but the va...

Development of a Modular Assay for Detailed Immunophenotyping of Peripheral Human Whole Blood Samples by Multicolor Flow Cytometry

The monitoring of immune cells gained great significance in prognosis and prediction of therapy responses. For analyzing blood samples, the multicolor flow cytometry has become the method of choice as it combines high specificity on single cell level with multiple parameters and high throughput. Here, we present a modular assay for the detailed immunophenotyping of blood (DIoB) that was optimiz...

Immunophenotyping of Nodal Peripheral T-cell Lymphomas and its Association with Epstein-Barr Virus

Background: Immunophenotyping in the rare group of nodal Peripheral T-cell Lymphomas (PTCL) exposes interesting features such as T-cell marker downregulation and paradoxically, the presence of reactive, clustered large-sized CD20 positive B-cells (B-cell proliferation). Epstein-Barr virus (EBV) has been suggested as a putative etiology in pathogenesis of B-cell lymphoma. We aimed to review the ...
