Mal-amido-PEG5-alkyne is a PEG linker containing a maleimide group and an alkyne. The hydrophilic PEG spacer increases solubility in aqueous media. The alkyne group can react with azide-bearing compounds or biomolecules via copper catalyzed azide-alkyne Click Chemistry to yield a stable triazole linkage. The maleimide group will react with a thiol group to form a covalent bond, enabling the connection of biomolecule with a thiol. Reagent grade, for research purpose.

The Norgen PCR Ranger 100 bp DNA Ladder is prepared to ensure quality and batch-to-batch consistency. Our PCR Ranger DNA Ladder contains eleven discrete fragments ranging from 50 bp to 1000 bp with a higher intensity reference band at 500 bp. This Ladder is ideal for assessment of a range of PCR product sizes.
Contents
1mL of premixed DNA ladder (0.5µg/10µL) in loading buffer (10mM EDTA, 10% glycerol, 0.015% bromophenol blue, and 0.17% SDS).

Recommended Use:
Mix thoroughly. For best results, load 10µL of DNA ladder per well. For precise mass determination with a densitometer, stain gel after electrophoresis using 0.5µg/mL ethidium bromide for 30-40 minutes. The table above shows the size and mass for each band based on 10µL ladder per well.
Storage:
Stable at room temperature. For longer term storage, -20°C is recommended.
This ladder was standardized using 10µL of DNA per lane on a 0.8 cm thick, 13 x 15 cm, 1.0% agarose gel run in TAE buffer.
Our most popular ring magnet plate. All of the features of our T480 magnet above with the added security of a cushion base For faster separations you can upgrade to the MSP500R which comes with all of the same features, just stronger magnets Like our ring magnet plates above, this plate comes in two magnet strengths. Features include solid aluminum alloy construction and hard coat anodized finish for years of trouble-free use, and compatible with any magnetic beads
