λ DNA-BstEII Digest

Catalog #SizeConcentrationGel Lanes
N3014S0.3 ml500 μg/ml150
N3014L1.5 ml500 μg/ml750

Description

The BstEII digest of lambda DNA (cI857 ind 1 Sam 7) yields 14 fragments suitable for use as molecular weight standards for agarose gel electrophoresis (1). The approximate mass of DNA in each of the bands is provided (assuming a 1.0 μg load) for approximating the mass of DNA in comparably intense samples of similar size.

Comes supplied with 1 vial of Gel Loading Dye, Blue (6X).

Notes

  1. For long term storage, store at -20°C. If samples need to be diluted, use TE or other buffer of minimal ionic strength. DNA may denature if diluted in dH20 and subsequently heated. Temperatures > 60°C may cause denaturation.
  2. The cohesive ends of fragments 1 and 4 may be separated by heating to 60°C for 3 minutes.
  3. 1X Gel Loading Dye, Blue:
    2.5% Ficoll-400
    11 mM EDTA
    3.3 mM Tris-HCL (pH 8.0@25°C)
    0.017% SDS
    0.015% bromophenol blue

Heat at 60C for 3 minutes to separate the cohesive ends of fragments 1 and 4.

To make it ready-to-load, dilute in TE buffer instead of water.
