Description
The Genebio ERBB2/D17S122 Dual Color Probe is designed for the detection of ERBB2 gene amplification frequently observed in solid malignant neoplasms e.g. breast cancer samples. Amplification of the proto-oncogene ERBB2, observed in approximately 20% of all breast cancer samples, has been correlated with a poor prognosis of the disease. Similar results have been obtained for a variety of other malignant neoplasms e.g. ovarian cancer, stomach cancer, and carcinomas of the salivary gland.
What is the Genebio ERBB2/D17S122 dual color probe used for?
The Genebio ERBB2/D17S122 dual color probe is a powerful tool used in genetic research and diagnostics. Specifically, it is designed to target and detect specific genetic alterations in the ERBB2 gene and the D17S122 locus.
The ERBB2 gene, also known as HER2, is a well-known oncogene that plays a crucial role in development and progression of certain types of cancer, notably breast cancer. Mutations or amplifications in the ERBB2 gene can lead to an overexpression of the HER2 protein, which is associated with a more aggressive form of the disease.
The D17S122 locus, on the other hand, is a microsatellite marker located on chromosome 17. Microsatellites are repeating DNA sequences that are highly polymorphic in nature, meaning they can vary in length among individuals. By analyzing the length of the microsatellite repeats at the D17S122 locus, researchers can gain valuable insights into the genetic diversity and stability of the genome.
The Genebio ERBB2/D17S122 dual color probe utilizes a combination of two different fluorescent dyes to simultaneously visualize the ERBB2 gene and the D17S122 locus in a sample. This allows researchers to determine the status of the ERBB2 gene (whether it is amplified or normal) and assess the stability of the D17S122 locus in a single experiment.
The probe employs a technique called fluorescence in situ hybridization (FISH) to bind to the target DNA sequences. FISH is a method that uses fluorescently labeled probes to detect and localize specific DNA sequences within a sample. In the case of the Genebio ERBB2/D17S122 dual color probe, the probe is designed to bind specifically to the ERBB2 gene and the D17S122 locus.
The dual color aspect of the probe refers to the use of two different fluorescent dyes. One dye is used to label the probe that targets the ERBB2 gene, while the other dye is used to label the probe that targets the D17S122 locus. When the probe binds to its target sequences, the fluorescent dyes emit light of different colors, allowing researchers to visualize and distinguish between the two targets.
By using the Genebio ERBB2/D17S122 dual color probe, researchers can gather important information about the genetic alterations in the ERBB2 gene and the genetic diversity and stability of the genome. This information can be crucial for understanding the development and progression of certain types of cancer, as well as for diagnostic purposes.
In addition to its applications in genetic research and diagnostics, the Genebio ERBB2/D17S122 dual color probe can also be used in other areas of study, such as cytogenetics and molecular pathology. Its versatility and effectiveness make it a valuable tool for scientists and researchers in various fields.
How does the Genebio ERBB2/D17S122 dual color probe work?
The Genebio ERBB2/D17S122 dual color probe is a powerful tool used in molecular biology and genetic research to detect specific genes and chromosomal abnormalities. This probe utilizes a unique dual color system that allows for simultaneous visualization of two different targets, ERBB2 and D17S122, within a cell or tissue sample.
The probe is made up of two distinct fluorescent dyes, each specific to one of the target genes. One dye is designed to bind specifically to the ERBB2 gene, which is associated with breast and ovarian cancer. The other dye is specific to the D17S122 gene, which is located on chromosome 17 and is often used as a reference marker for chromosomal abnormalities.
When the probe is applied to a sample, it hybridizes or binds to the complementary DNA sequences of the target genes within the cell or tissue. This binding is highly specific, meaning that the probe only attaches to the intended target genes. The fluorescent dyes attached to the probe then emit light when excited by a specific wavelength of light.
The dual color system of the probe allows for easy differentiation and visualization of the two target genes. The ERBB2 gene is typically labeled with a green fluorescent dye, while the D17S122 gene is labeled with a red fluorescent dye. When viewed under a fluorescence microscope, cells or tissues with both target genes present will exhibit a yellow color, indicating the overlap of green and red fluorescence.
This dual color visualization provides researchers with valuable information about the genetic alterations in the ERBB2 gene and the stability of the D17S122 locus. For example, if the ERBB2 gene is amplified or overexpressed, it may suggest a more aggressive form of breast or ovarian cancer. Additionally, analyzing the stability of the D17S122 locus can give insights into the genetic diversity within a population and the stability of the genome.
The Genebio ERBB2/D17S122 dual color probe works through a technique called fluorescence in situ hybridization (FISH). FISH uses fluorescently labeled probes to bind to specific DNA sequences within a sample. In this case, the probe is designed to bind to the ERBB2 gene and the D17S122 locus.
The dual color aspect of the probe is achieved by using two different fluorescent dyes. One dye is used to label the probe targeting the ERBB2 gene, and the other dye is used to label the probe targeting the D17S122 locus. When the probe binds to its target sequences, the fluorescent dyes emit light of different colors. This allows researchers to visualize and distinguish between the two targets.
By using the Genebio ERBB2/D17S122 dual color probe, researchers can gather important information about the genetic alterations in the ERBB2 gene and the genetic diversity and stability of the genome. This information can aid in understanding the development and progression of certain types of cancer and can also be used for diagnostic purposes.
