Descrizione generale
Gel loading solution is used as a tracking dye during electrophoresis. The dyes have a slight negative charge and will migrate the same direction as DNA, allowing the user to monitor the progress of molecules moving through the gel. The rate of migration varies with gel composition. Dilute 1:6 with sample before loading.
Applicazioni
Suitable for use with agarose or non-denaturing polyacrylamide gel electrophoresis (PAGE), which may be part of Northern and Southern blot hybridization procedures.
Componenti
Gel loading buffer contains 0.25% bromophenol blue, 0.25% xylene cyanol, and 40% sucrose.
Altre note
Band migration can be expected as follows:
On polyacrylamide gels, xylene cyanole comigrates with approximately 450-460 bp DNA, while bromophenol blue comigrates with 15-100 bp DNA. On 0.5 – 1.4% agarose gels, xylene cyanole comigrates with 4 kb dsDNA, while bromophenol blue comigrates with 300 bp dsDNA.

We have characterized an early series of 5,6-bridged dioxinoquinolones which behaved strikingly different from typical quinolones. The 5,6-bridged dioxinoquinolones inhibited Escherichia coli DNA gyrase supercoiling activity but, unlike typical quinolones, failed to stimulate gyrase-dependent cleavable complex formation. Analogous unsubstituted compounds

While screening Le(a+b+)Polynesian DNA samples for a candidate Se(w) allele, a point mutation (C571-->T) resulting in a new stop codon (Arg191-->stop) in the alpha(1,2)fucosyltransferase gene (FUT2) was identified. This point mutation resulted in the gaining of a new restriction enzyme
