Basic blue 148: a rapid stain for T helper cells
1Department of Pathology, Case Western Reserve University School of Medicine, Cleveland, Ohio, USA.
Summary
A novel staining technique using Basic blue 148 dye can rapidly identify T helper cells in blood. This method offers a quick and effective screening tool for hematology and immunology labs.
Area of Science:
- Hematology
- Immunology
- Cell Biology
Background:
- Identifying T helper cells is crucial in hematology and immunology.
- Existing methods for T helper cell identification can be time-consuming.
Purpose of the Study:
- To evaluate the efficacy of C.I. basic blue 148 as a rapid stain for T helper cells.
- To determine if Basic blue 148 offers a specific and efficient staining method.
Main Methods:
- Peripheral blood and bone marrow specimens were fixed.
- Specimens were briefly exposed to an aqueous solution of C.I. basic blue 148.
- Stained cells were examined under ordinary incandescent illumination.
Main Results:
- T helper cell nuclei and cytoplasm showed a distinct deep red-violet color.
- No other normal blood or bone marrow cells exhibited this intense staining.
- The total staining time was only 1 minute.
Conclusions:
- C.I. basic blue 148 is a promising stain for T helper cells.
- This technique provides a rapid screening method for T helper cells in blood specimens.
- The stain is suitable for use in routine hematology and immunology laboratories.
