Real Time RT-PCR02:57

Real 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.
The real-time quantification of the number of amplified products is...
DNA Isolation01:24

DNA Isolation

DNA isolation protocols can be fast and straightforward or complex and time-consuming depending on the type and quality of DNA required for further processing. For example, plasmid DNA extraction is a bit more complicated than genomic DNA extraction because of the need for an appropriate lysis method to separate plasmid DNA from gDNA during isolation. However, for specific applications, such as long-range DNA sequencing that require a good yield of high- quality DNA samples, we need to follow...

Area of Science:

  • Genomics
  • Molecular Biology
  • Human Genetics

Background:

  • Alu repetitive elements are abundant in primate genomes.
  • Genetic polymorphisms and mutations can arise from alterations in these elements.
  • DNA fingerprinting is crucial for genetic analysis and mutation detection.

Purpose of the Study:

  • To describe a protocol for Alu PCR-based DNA fingerprinting.
  • To detail the use of fluorochrome-labelled primers and capillary electrophoresis.
  • To explain the analysis of complex electrophoretic patterns for genetic variation.

Main Methods:

  • Utilizing Alu PCR with two fluorochrome-labelled primers targeting Alu sequences.
  • Performing Polymerase Chain Reaction (PCR) for DNA amplification.
  • Analyzing amplified products via capillary electrophoresis to generate complex electrophoretic patterns.

Main Results:

  • Alu PCR enables simultaneous analysis of numerous genomic loci.
  • Electrophoretic patterns reveal sample-to-sample variability.
  • Variability is attributed to Alu retrotransposon insertions, deletions, sequence changes, or inter-Alu sequence length variations.

Conclusions:

  • Alu PCR is an effective and accessible method for DNA fingerprinting.
  • The technique facilitates the detection of genetic polymorphisms and mutations.
  • It provides a powerful tool for studying genomic alterations in human and primate DNA.
