Fast, sensitive analysis of DNA and RNA samples

Invitrogen E-Gel DNA Ladders are double stranded DNA fragments of defined mass and size suspended pre-mixed with gel loading buffer. These ladders are formulated for optimal performance on Invitrogen E-Gel Precast Agarose Gels. For best results, use with Invitrogen E-Gel Sample Loading Buffer.

Highlights of E-Gel DNA Ladders include:

  • Performance—designed for use on E-Gel agarose gel cassettes
  • Sharp, clear bands—chromatography-purified DNA fragments that yield sharp, clean bands
  • Versatile—fragment sizes from 10 bp to 15 kb cover the full range or just the size you need
  • Convenient—premixed in Invitrogen E-Gel Sample Loading Buffer and dye, and stable at room temperature


E-Gel DNA Ladder selection guides

Use the DNA ladder suited to a specific application for accurate band analysis. Table 1 lists E-Gel DNA Ladders available by high-to-low bp range. For optimal performance, use the right combination of E-Gel DNA Ladders and E-Gel Precast Agarose Gels as specified in Table 2.

E-Gel Sample Loading Buffer

E-Gel Sample Loading Buffer is ready to use out of the tube, requiring no further dilution. It contains the unique tracking dyes xylene cyanol FF (XCFF) and tartrazine; these dyes visually track DNA migration during electrophoresis, and indicate when maximum resolution is achieved.
