Agarose gel electrophoresis.
MATERIALS 6x Gel-loading buffer Agarose solutions (please see Step 3) DNA samples DNA size standards Samples of DNAs of known size are typically generated by restriction enzyme digestion of a plasmid or bacteriophage DNA of known sequence. Alternatively, they are produced by ligating a monomer DNA fragment of known size into a ladder of polymeric forms. DNA staining solution For a discussion of...
متن کاملAgarose gel electrophoresis.
Agarose gel electrophoresis is used to separate DNA or RNA molecules based upon their size.
متن کاملAlkaline agarose gel electrophoresis.
INTRODUCTION Alkaline agarose gels are run at a pH that is sufficiently high to denature double-stranded DNA. The denatured DNA is maintained in a single-stranded state and migrates through the alkaline gel as a function of its size. Alkaline agarose gels are used chiefly to measure the size of first and second strands of cDNA (Construction of cDNA Libraries Stage 1: Synthesis of First-strand c...
متن کاملResolving Transferrin Isoforms via Agarose Gel Electrophoresis.
OBJECTIVE Cerebrospinal fluid (CSF) leaks may present as rhinorrhea or otorrhea and can lead to life-threatening complications if not detected. The usefulness of the morpholinopropanesulfonic acid (MOPS)-histidine buffer in detecting β₂-transferrin, which is only found in the cerebrospinal fluid, was compared with the standard barbital buffer. METHODS We evaluated 20 aural or nasal patient sp...
متن کاملTrapping of megabase-sized DNA molecules during agarose gel electrophoresis.
Megabase DNA molecules become trapped in agarose gels during electrophoresis if the electric field exceeds a few volts per cm. Fluorescence microscopy reveals that these molecules invariably arrest in U-shaped conformations. The field-vs.-size dependence for trapping indicates that a critical molecular tension is required for trapping. The size of unligated lambda-ladders, sheared during gel el...
