Summary
Concurrent DNA and RNA analysis using flow cytometry offers insights into cell DNA content and transcriptional status. This method is crucial for classifying hematoreticular malignancies like multiple myeloma.
Area of Science:
- Cellular biology
- Molecular diagnostics
- Hematology
Background:
- Flow cytometry is a powerful technique for analyzing cellular properties.
- Assessing both DNA content and RNA status provides a comprehensive view of cell function.
- Cell viability is critical for accurate flow cytometry analysis.
Purpose of the Study:
- To describe a method for concurrent DNA and RNA analysis in cells using flow cytometry.
- To highlight the utility of this technique in the study of hematological malignancies.
Main Methods:
- Utilizing metachromatic fluorochromes that bind to DNA via intercalation.
- Employing electrostatic binding for single-stranded RNA.
- Ensuring the use of freshly prepared cells due to viability requirements.
Main Results:
- Simultaneous DNA/RNA analysis provides data on DNA content and cellular transcriptional status.
- The method is applicable to freshly prepared cells.
Conclusions:
- Concurrent DNA/RNA flow cytometry is valuable for the classification and biological assessment of hematoreticular malignancies.
- This technique is particularly relevant for multiple myeloma research.

02:34DNA Microarrays
Microarrays are high-throughput and relatively inexpensive assays that can be automated to analyze large quantities of data at a time. They are used in genome-wide studies to compare gene or protein expression under two varied conditions, such as healthy and diseased states. Microarrays consist of glass or silica slides on which probe molecules are covalently attached through surface functionalization. Most commonly, the slides are prepared through the chemisorption of silanes to silica...
02:57Real Time RT-PCR
Real-time reverse transcription-polymerase chain reaction, or Real-time RT-PCR, is an analytical tool used to determine the expression level of target genes. The method involves converting mRNA to complementary DNA with the help of an enzyme known as reverse transcriptase, followed by the PCR amplification of the cDNA. These two processes can be performed simultaneously in a single tube or separately as a two-step reaction.

01:23Flow Cytometry
The development of flow cytometry techniques began in 1934 with initial attempts by Andrew Moldavan, a bacteriologist who counted the cells in a flowing capillary system. Moldavan pumped cells through a capillary tube focused under a microscope for visualization. The invention of photometry allowed the measurement of differentially-stained cells, and Louis Kamentsky developed the first multiparameter flow cytometer in 1965 to identify and count the cancer cells in cervical tissue specimens.
