20.1: DNA Isolation, Gel Electrophoresis, and PCR
网页The resulting DNA, because it is made up of long polymers, forms a gelatinous mass. This method extracts all the nucleic acid within a cell. This includes genomic DNA (all the DNA in the genome), as well as RNA. If this DNA was to be used for further study, the RNA would often be digested with an enzyme to remove it.
Agarose Gel Electrophoresis for the Separation of DNA Fragments
网页2012年4月20日 · Traditional agarose gels are most effective at the separation of DNA fragments between 100 bp and 25 kb. To separate DNA fragments larger than 25 kb, one will need to use pulse field gel electrophoresis 6, which involves the application of alternating current from two different directions.
Gel Extraction - an overview | ScienceDirect Topics
网页Gel extraction (gel purification) is commonly used to isolate DNA from an agarose gel. After melting the agarose slice containing the DNA of interest, the protocol includes steps that are similar to those followed in other silica-membrane spin columns. This protocol is modified from the manufacturer’s handbook (QIAquick Spin Handbook 03/2008).
Addgene: Protocol - How to Run an Agarose Gel
网页Gel electrophoresis is the standard lab procedure for separating DNA by size (e.g., length in base pairs) for visualization and purification. Electrophoresis uses an electrical field to move the negatively charged DNA through an agarose gel matrix toward a positive electrode.
Extraction of DNA from Agarose Gels | SpringerLink
网页7 Altmetric. Abstract. A common step in cloning experiments is the purification of DNA fragments prior to ligation. Often, both the insert and vector DNA fragments will be derived from restriction endonuclease digests and, thus, will be mixed with enzymes, salts, and possibly other DNA fragments that may inhibit the ensuing ligation reaction.
