Propargyl-PEG4-5-nitrophenyl carbonate is heterobifunctional reagent with a propargyl group and nitrophenyl group. The propargyl group enales the formation of triazole linkage with azide compounds or biomolecules via copper catalyzed Click Chemistry. Nitrophenyl group is reactive towards the amino group of lysine by means of stable urethane linkages. The PEG units enhance the solubility of the molecule in aqueous media.

The Norgen LowRanger 100 bp DNA Ladder is prepared to ensure quality and batch-to-batch consistency. Our LowRanger contains eleven discrete fragments ranging from 100 bp to 2000 bp in 100 bp increments with a higher intensity reference band at 500 bp. This Ladder is ideal for fast running times and accurate visual determination.
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.
