Optimizing a multicolor immunophenotyping assay.

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...

Multicolor interphase cytogenetics for the study of plasma cell dyscrasias.

Specific chromosomal abnormalities such as chromosome 13 deletions and some translocations affecting the immunoglobulin heavy chain (IGH) gene, namely t(4;14)(p16;q32) and t(14;16)(q32;q23) have been associated with an adverse prognosis in multiple myeloma. Conventional cytogenetic techniques fail to detect these aberrations in the majority of cases. Thus, we have developed a novel set of inter...

Setting up and calibration of a flow cytometer for multicolor immunophenotyping.

A practical approach to multicolor flow cytometry for immunophenotyping.

Through a series of novel developments in flow cytometry hardware, software, and dye-chemistry it is now possible to simultaneously measure up to 11 distinct fluorescences and two scattered light parameters on each cell. Such advanced multicolor systems have a number of advantages over current two- and three-color flow cytometric measurements. They provide a large amount of novel information fo...

Evaluation of a multicolor, single-tube technique to enumerate lymphocyte subpopulations.

To evaluate the fully automated FACSCanto software, we compared lymphocyte subpopulation counts obtained using three-color FACSCalibur-CELLQuest and six-color FACSCanto-FACSCanto software techniques. High correlations were observed between data obtained with these techniques. Our study indicated that FACSCanto clinical software is accurate and sensitive in single-platform lymphocyte immunopheno...
