Instastain® ethidium bromide staining card

Discover

• Quick and easy
• No pipetting required, delivers a small amount of stain to the agarose
gel via a special paper backing
• Place the card on the gel and wait: 8-10 min. for 1% agarose gels and 3-5 min. for 0.8% agarose gels
• Each card will stain a gel up to 7 x 7 cm in size

ClearLine® EmeralDye Stain

Discover

High sensitivity even for small fragments, superior signal to noise ratio, can be used in a classical gel staining procedure as well as in post staining procedures, 4 - 6 µl in 100 ml of agarose.

Midori Green stains

Discover

• For the labeling of nucleic acids
• Non-carcinogenic alternative to ethidium bromide
• Storage solution without DMSO

3 versions:
• Midori Green Advance: high sensitivity for small fragments, background noise reduction, dye to be added during the preparation of the gel or following the migration, 4 - 6 µl for 100 ml of agarose; main excitation wavelength 490 nm / secondary 290 nm; emission wavelength 530 nm
• Midori Green Direct: mix directly with the samples ratio 10:1 , background noise reduction, included a dye load; main excitation wavelength 490 nm / secondary 270 nm; emission wavelength 530 nm
• Midori Green Xtra: ultra sensitive dye when excited in blue or blue / green light (detecting nucleic acids aquantity detection lower than 4 ng), for excitation in the UV rather choose the Midori Green Advance, very low background noise, 4 - 8 µl for 100 ml of agarose; main excitation wavelength 482 nm / secondary 250 nm; emission wavelength 509 nm
