ZGF1331
250 (5 x 50) μg The ladder is composed of fifteen chromatography-purified individual DNA fragments (in base pairs): 20000, 10000, 7000, 5000, 4000, 3000, 2000, 1500, 1000, 700, 500, 400, 300, 200, 75. It contains three reference bands (5000, 1500 and 500 bp) for easy orientation. The ladder is dissolved in TE buffer. |
ZGen50 DNA Ladder
|
The ZGen50 DNA Ladder consists of 14 liner double stranded DNA bands of 50, 100, 150, 200, 250, 300, 350, 400, 450, 500, 750, 1100, 1800 and 3000 base pair. This Gen50-Plus DNA ladder is specially prepared for visualizing of the DNA fragments on the gel. The intensity of 300 bp band has been increased to yield reference indicator.

50X TAE Buffer |
TAE buffer is the most commonly used electrophoresis buffer for agarosegels. It has a lower buffer capacity than TBE, but double-stranded linear DNA migrates 10% faster with the same resolution through TAE-containing agarosegels. The working concentration is 1X or 0.5X TAE at room temperature. |

5X TBE Buffer |
TBE buffer is the electophoresisbuffer for polyacrylamidegels and agarosegels. TBE has a higher buffering capacity than TAE. Normally, it is applied in a concentration of 1X for polyacrylamide gels and 0.5X for agarose gels and "band shifts" (gel mobility shift assay). |

Ethidium Bromide Solution |
Etbr is the most commonly used dye for staining DNA during or after polyacrylamide or agarose gel electrophoresis. Excitation with light at a wave length of 254 nm is absorbed by the DNA and transferred to ethidium bromide. Excitation at 366 nm directly excites the dye. An aqueous stock solution is prepared at a concentration of 10 mg/ml and employed at 0.2~0.5 μg/ml. Staining is performed after the gel run (especially PAGE) or during the gel run (agarose). The latter allows the observation of the gel run by control under UV light. Ethidium bromide is added to the agarose solution. Please note, that "prestaining" may lead to artifacts.Storage: Store the stock solution at 4 ℃, prevent direct light exposure. |
