Summary
Long-polymerase chain reaction (PCR) enables amplification of large DNA fragments, overcoming standard PCR limitations for analyzing DNA rearrangements. This method offers a faster, more convenient alternative to traditional techniques like Southern blotting.
Area of Science:
- Molecular Biology
- Genetics
Background:
- Standard polymerase chain reaction (PCR) is limited to amplifying small DNA fragments.
- Analyzing large-scale DNA rearrangements traditionally requires complex methods like Southern blotting.
Purpose of the Study:
- To introduce long-polymerase chain reaction (PCR) protocols for amplifying large DNA fragments.
- To provide a more rapid and convenient method for analyzing gross DNA rearrangements.
Main Methods:
- Utilizing combinations of DNA polymerases with high polymerase activity and error-correction abilities.
- Developing optimized long-polymerase chain reaction (PCR) protocols.
Main Results:
- Successful amplification of extended DNA fragments previously not possible with standard PCR.

01:24DNA 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...
02:35RACE - Rapid Amplification of cDNA Ends
Rapid Amplification of cDNA Ends, or RACE, is one of the most effective methods to obtain a full-length cDNA from an mRNA sequence between a known internal region to the unknown sequence at the 5’ or 3’ end. The unknown region is cloned in the cDNA by a gene-specific primer that binds the known end, and a hybrid primer that attaches a predefined anchor sequence to the unknown end of the cDNA. The sequence in between is amplified by PCR with an anchor primer and a gene-specific primer.

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.
