DNA Ladder

  • 25bp DNA Marker

    25bp DNA Marker

    The ladder contains eleven double-stranded DNA bands that are designed for sizing and approximate quantification of wide-range molecular weight standards on agarose gels. The ladder is composed of nine purified individual DNA fragments (in base pairs): 300, 200, 175, 150, 125, 100, 75, 50, and 25. DNA quantities of each band per 5ul loading are as follow: 25 bp (85 ng), 50 bp (85 ng), 75 bp (55 ng), 100 bp (72 ng), 125 bp (20 ng), 150 bp (25 ng), 175 bp(30 ng), 200 bp (32 ng), and 300 bp (110 ng). 

  • 50 bp DNA Ladder

    50 bp DNA Ladder

    The ladder contains 16 double-stranded DNA bands that are designed for sizing and approximate quantification of wide-range molecular weight standards on agarose gels. The product is ready-to-use and premixed with 1×Loading Buffer for direct loading 3-6 μl on gel electrophoresis. The ladder is composed of 16 purified individual DNA fragments (shown in right figure). DNA quantities of each band per 5ul loading are as follow: 50 bp (35.5 ng), 100 bp (30 ng), 150 bp (13.5 ng), 200 bp (22.5 ng), 250 bp (22.5 ng), 300 bp (13.5 ng), 350 bp (31.5 ng), 400 bp (15 ng), 500 bp (46 ng) , 600 bp (27 ng) , 700 bp (31.5 ng) , 800 bp (30 ng) , 900 bp (33.5 ng) , 1000 bp (33 ng) , 1500 bp (50 ng) and 3000 bp (64 ng).

  • 100 bp Plus DNA Ladder

    100 bp Plus DNA Ladder

    The ladder contains thirteen double-stranded DNA bands that are designed for sizing and approximate quantification of wide-range molecular weight standards on agarose gels. The product is ready-to-use and premixed with 1×Loading Buffer for direct loading 3-5 μl on gel electrophoresis. The ladder is composed of thirteen purified individual DNA fragments (in base pairs): 3000, 2000, 1500, 1000, 900, 800, 700, 600, 500 (intense band for easy orientation), 400, 300, 200, and 100.

  • 1 kb DNA Ladder II

    1 kb DNA Ladder II

    The ladder contains thirteen double-stranded DNA bands that are designed for sizing and approximate quantification of wide-range molecular weight standards on agarose gels. The ladder is composed of nine purified individual DNA fragments ranging from 250-10000 bp. The enhanced intensity of the 1000 bp and the 3000 bp fragments are designed to serve as reference bands.

  • BR DNA marker 100-10Kb

    BR DNA marker 100-10Kb

    The ladder contains nineteen double-stranded DNA bands that are designed for sizing and approximate quantification of wide-range molecular weight standards on agarose gels. The ladder is composed of nine purified individual DNA fragments ranging from 100-10000 bp. The enhanced intensity of the 500 bp, 1.5K and the 3K fragments are designed to serve as reference bands.
