Real-Time PCR and Gene Expression |
Gene expression is a highly regulated process that determines when, where, and under what conditions specific genes are activated within an organism. This regulation is crucial for proper functioning, development, and adaptation. Genes are expressed at different times and locations based on internal factors like cell cycle stages and hormonal signals, as well as external factors such as environmental changes. Transcription factors, enhancers, and silencers play key roles in triggering or preventing gene expression. The products of transcription include mRNA, which serves as a template for protein synthesis, and various non-coding RNAs that regulate gene expression and cellular functions.
TaqMan gene expression assays and arrays are advanced tools used by scientists to measure and analyze gene expression with high specificity and sensitivity. These assays utilize real-time PCR to quantify RNA levels and offer over 2.8 million predesigned primer/probe sets covering more than 30 species. This extensive collection helps allow for precise detection and quantification of gene expression, facilitating research in developmental biology, disease mechanisms, and therapeutic interventions. The data generated from these assays help provide valuable insights into the diverse expression products that determine the growth and health of an organism.
¿Cuándo, dónde y en qué condiciones se expresan los genes? ¿Qué desencadena, o impide, esta expresión? Los científicos están descubriendo la sorprendente variedad de productos de transcripción y traslación, y cómo estos diferentes productos de expresión determinan el crecimiento y la salud de un organismo.
Con un contenido cuidadosamente seleccionado, los ensayos y arrays de expresión de genes TaqMan pueden generar datos de alta calidad para una amplia gama de estudios, proporcionando más de 2.3 millones de conjuntos de primers/sondas prediseñados que cubren más de 30 especies.
Thermo Fisher Scientific has developed two chemistries for the sensitive, accurate quantification of mRNA using real-time PCR: Applied Biosystems TaqMan probe-based chemistry and Applied Biosystems SYBR green dye-based chemistry.
