よくあるご質問(FAQ)
Can I know the sequences of Invitrogen DNA ladders?
Sequences of Invitrogen DNA and RNA ladders are proprietary.
Are Invitrogen DNA ladders composed of linear or circular/supercoiled DNA?
Invitrogen DNA ladders contain linear dsDNA fragments.
Are Invitrogen DNA ladders composed of single-stranded or double-stranded DNA fragments?
Invitrogen DNA ladders are composed of double-stranded DNA fragments only.
I'm seeing anomalous migration of my DNA ladder. What happened?
This can happen if the marker was heated. Please ensure that the ladders are not heated before use.
What is the difference between the TrackIt DNA Ladders and other DNA ladders?
TrackIt DNA Ladders contain two tracking dyes in the sample buffers, which serve as visual markers for tracking electrophoresis progress through the gel, and also to indicate when maximum resolution is achieved. The tracking dyes should not obscure your visualization of DNA bands in the ladder, as the dyes run outside the limits of most DNA bands in the ladder.
TrackIt Cyan/Orange Loading Buffer is formulated with unique tracking dyes, Xylene Cyanol FF and Orange G. We recommend TrackIt Cyan/Orange Loading Buffer for DNA fragments between 10 bp and 1 kb.
The TrackIt Cyan/Yellow Loading Buffer is formulated with unique tracking dyes, Xylene Cyanol FF and Tartrazine. We recommend TrackIt Cyan/Yellow Loading Buffer for DNA fragments between 100 bp and 10 kb. The molecular weights are Xylene Cyanol FF, 638.6; Orange G, 452.4; Tartrazine, 534.4.
Note: The TrackIt DNA Ladders are not recommended for use with polyacrylamide gels and are not designed for quantitation.
