Figure 1

Whole blood from a healthy donor was stained with the StainExpress Immune Cell Composition Cocktail. Staining was carried out for 10 minutes at room temperature (19−25 °C). Subsequently, red blood cells were lysed by incubation with 1× Red Blood Cell Lysis Solution at room temperature for 15 minutes. Cells were analyzed by flow cytometry using the MACSQuant Analyzer 10.
To exclude debris, a gate was set on FSC versus SSC encompassing all cells (A). To exclude residual erythrocytes and to identify leukocytes, CD45 was used to gate on CD45
+
leukocytes (B), and dead cells were excluded by 7-AAD (C). CD3
+
cells were identified (D) and discriminated into T cells and NKT cells based on expression of CD56 (E). T cells were further divided into CD4
+
and CD8
+
T cells (F). Among CD3
cells, monocytes were defined by CD14 expression and B cells by CD19 expression (G). The remaining CD14

Specifications for StainExpress™ Immune Cell Composition Cocktail, human

Overview

StainExpress™ Immune Cell composition Cocktail helps standardize the flow cytometric evaluation of immune cell fractions and composition from human blood material. This pre-formulated multicolor panel is designed for immunofluorescent staining of whole blood, peripheral mononuclear cells (PBMCs), lysed whole blood samples, or other single-cell suspensions from human tissue, to identify human monocytes, neutrophils, eosinophils, and T, B, and NK lymphocyte populations as well as CD4
+
, CD8
+
, and NKT cell subsets.

Detailed product information

Background information

The StainExpress Immune Cell Composition Cocktail is designed for standardized determination of cell viability and composition of immune cells, helping to achieve reliable results for raw material testing, in-process, and quality control steps in cell manufacturing as well as reproducible analysis on human whole blood. The cocktail offers consistent formulation in carefully dried down cocktails containing our REAfinity™ Recombinant Antibodies.
REAfinity Antibodies are generated in a biologically and chemically defined
in vitro
expression system to guarantee maximum purity and lot-to-lot consistency. The genetic sequence is engineered to lack binding to Fcγ receptors (FcγRs). Binding to FcγRs is one of the main causes of background signal in flow cytometry analysis.
Flow cytometric analysis of the Immune Cell Composition Cocktail can be conducted on several flow cytometer equipped with a red (638 nm), a blue (488 nm), and a violet (405 nm) laser, for example, the MACSQuant
®
Analyzer 10 or MACSQuant Analyzer 16.

Applications

  • Evaluation of leukocyte subsets in whole blood, leukapheresis products, PBMCs, or other single-cell suspensions from human tissue
  • Determination of cell counts and population subsets during CAR T cell manufacturing procedures using the MACSQuant Analyzer
