Propargyl-PEG4-NHS ester is an amine reactive PEG linker with an alkyne group. Under the copper catalyzation, alkyne group can react with azide-bearing biomolecules to form a stable triazole linkage. The hydrophilic PEG spacer increases solubility in aqueous media. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

Ten discrete fragments ranging from 300 bp to 5000 bp
The Norgen MidRanger 1 kb DNA Ladder is prepared to ensure quality and batch-to-batch consistency. Our MidRanger contains ten discrete fragments ranging from 300 bp to 5000 bp. This Ladder is ideal for sizing larger PCR products (>1kb) and most cloning applications.
Contents: 1mL of premixed DNA ladder (0.5µg/10µL) in loading buffer (10mM EDTA, 10% glycerol, 0.015% bromophenol blue, and 0.17% SDS).
Ladder Properties: • Ten discrete fragments ranging from 300 bp to 5000 bp

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.
Bis-propargyl-PEG9 is crosslinking reagent containing two propargyl groups. These functional groups enable the formation of triazole linkages with azide-bearing compounds with the presence of copper catalyst. The hydrophilicity of the molecule is improved because of the PEG chain. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.
