Dimidium Bromide CAS 518-67-2

1. Nucleic acid insertion probe:
Can be inserted into the double helix structure of nucleic acids to form stable complexes. This characteristic makes it an important tool for studying the structure and function of nucleic acids. In biological research, researchers can use it as a probe to label specific nucleic acid sequences, thereby tracking their distribution and dynamic changes within cells.
For example, when studying gene expression regulation, researchers can mark specific gene promoter regions and observe the binding of transcription factors to that region, thereby revealing the regulatory mechanism of gene expression.

2. DNA damage detection:
The binding ability with DNA enables it to be used for detecting DNA damage. When DNA is damaged by physical or chemical factors, its double helix structure may change, leading to a decrease in its binding ability to DNA. The degree of DNA damage can be indirectly evaluated by detecting changes in the binding of bromodimenium bromide to DNA.
This characteristic is of great significance in medical research, especially in evaluating the efficacy and toxicity of anti-cancer drugs. Researchers can use it to detect the damaging effect of anti-cancer drugs on tumor cell DNA, thereby screening anti-cancer drugs with high efficiency and low toxicity.

3. Cell apoptosis research:
Apoptosis is a process of programmed cell death, which is of great significance for maintaining the homeostasis of the body and preventing the occurrence of diseases. Bromonium bromide can be used to detect the occurrence of cell apoptosis by binding to nucleic acid fragments released from apoptotic cells.
In medical research, researchers can use its labeled nucleic acid fragments released by apoptotic cells to observe the distribution and quantity of apoptotic cells through flow cytometry or fluorescence microscopy, in order to evaluate the effects of different treatment methods on cell apoptosis.

1. PCR amplification:
Bromonium bromide can be used as a fluorescent dye in polymerase chain reaction (PCR). When the PCR reaction is carried out, bromodimenium bromide will be embedded into the newly synthesized DNA double strand, emitting a fluorescent signal. By detecting the intensity of fluorescence signals, the progress and product quantity of PCR reactions can be monitored in real-time.
This characteristic makes it one of the important fluorescent dyes in real-time quantitative PCR (qPCR). Compared with traditional fluorescent dyes such as SYBR Green, it has higher sensitivity and specificity, and can more accurately detect low abundance DNA templates.

2. DNA electrophoresis analysis:
In DNA electrophoresis analysis, it can be used to stain DNA fragments. When DNA fragments migrate under the action of an electric field, they will embed into the double stranded DNA, causing it to emit a fluorescent signal. By observing the fluorescence signal through a fluorescence imaging system, the separation of DNA fragments can be clearly seen.
Compared with traditional ethidium bromide (EB) staining, it has lower toxicity and higher sensitivity. In addition, its fluorescence signal is more stable and less susceptible to environmental factors, making it more suitable for high-precision DNA electrophoresis analysis.

3. Nucleic acid hybridization:
Nucleic acid hybridization is one of the commonly used techniques in molecular biology for detecting the presence of specific nucleic acid sequences. It can be used as a hybridization indicator. When the probe binds to the target nucleic acid sequence, bromodimenium bromide will be embedded into the hybrid double strand, emitting a fluorescent signal.
By detecting the intensity of the fluorescence signal, the binding status between the probe and the target nucleic acid sequence can be determined. This feature makes it widely applicable in nucleic acid hybridization techniques such as gene chips, Southern blot, and Northern blot.

1. Nucleic acid sensor:
Based on its strong binding ability with nucleic acids, researchers can develop nucleic acid sensors for detecting specific nucleic acid sequences. This type of sensor typically consists of biometric elements (such as nucleic acid probes) and signal conversion elements (such as electrochemical or optical sensors).
When the target nucleic acid sequence is present, it will bind with the nucleic acid probe to form a complex, causing a change in the fluorescence signal of bromodimenium bromide.

By detecting changes in fluorescence signals, quantitative detection of target nucleic acid sequences can be achieved. This nucleic acid sensor has broad application prospects in fields such as disease diagnosis, environmental monitoring, and food safety.

2. Protein nucleic acid interaction sensor:
The interaction between proteins and nucleic acids is the foundation of many important biological processes within cells. Based on dimidium bromide binding ability with nucleic acids, researchers can develop protein nucleic acid interaction sensors for studying this interaction.

This type of sensor typically uses bromide labeled nucleic acid probes, and when a protein binds to the nucleic acid probe, it causes a change in the fluorescence signal of bromide labeled nucleic acid probes. By detecting changes in fluorescence signals, the mechanism and kinetic parameters of protein nucleic acid interactions can be revealed. This is of great significance for understanding the biological processes within cells and developing new drug targets.

3. Intracellular biosensors:
With the development of synthetic biology and metabolic engineering, researchers are increasingly focusing on online monitoring of intracellular biological parameters such as metabolite concentration and enzyme activity.

Based on its fluorescence characteristics, researchers can develop intracellular biosensors for real-time monitoring of these biological parameters.

This type of sensor typically utilizes gene coding technology to bind it or its derivatives to specific biomolecules, such as metabolite responsive transcription factors, to form a fluorescent reporting system.

When the concentration of metabolites inside the cell changes, it triggers the response of the fluorescence reporting system, resulting in a change in the fluorescence signal. By detecting changes in fluorescence signals, real-time monitoring of biological parameters such as metabolite concentration and enzyme activity within cells can be achieved. This is of great significance for optimizing the metabolic pathways of cell factories and increasing the yield of target products.
