DNA Agarose Gel Electrophoresis02:35

DNA Agarose Gel Electrophoresis

120.2K
Agarose gel electrophoresis is a laboratory technique commonly used to separate DNA fragments by size. However, it can also be used to isolate and purify DNA fragments using a gel extraction protocol.
Gel extraction follows five major steps: running gel electrophoresis to separate fragments, isolating the individual bands, extracting DNA from those bands, and removing the dye and salts from the extracted mixture to obtain pure DNA.
In cloning experiments, both the insert and vector DNA...

DNA Isolation

46.3K
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:

  • Biomaterials Science
  • Molecular Biology
  • Tissue Engineering

Background:

  • Agarose hydrogels are common scaffolds in tissue engineering.
  • Extracting high-integrity RNA from these hydrogels for molecular analysis is challenging due to agarose interference.
  • RNA integrity in cell/agarose constructs is not well understood.

Purpose of the Study:

  • To investigate methods for obtaining high-integrity RNA from cell/agarose constructs.
  • To establish reproducible methodologies for RNA extraction from these complex matrices.

Main Methods:

  • Evaluation of various RNA extraction techniques using spectrophotometry and microfluidic capillary electrophoresis.
  • Utilized a mono-phasic solution of phenol and guanidine isothiocyanate.
  • Employed silica-based membrane filter columns for RNA purification.

Main Results:

  • The combination of phenol/guanidine isothiocyanate solution and a silica membrane column yielded sufficient RNA integrity.
  • This method enabled downstream applications like fluorescent-tagged quantitative polymerase chain reaction (qPCR).

Conclusions:

  • Phenol/guanidine isothiocyanate solution with a silica membrane column is effective for high-integrity RNA extraction from polysaccharide-rich cell/agarose constructs.
  • This methodology supports further research in cellular and tissue engineering involving agarose hydrogels.
