N-(Amino-PEG1)-N-bis(PEG2-propargyl) HCl salt is a crosslinker consisting of an amino group with two propargyl groups. The amino group is reactive with carboxylic acids, activated NHS esters, carbonyls (ketone, aldehyde) etc. The propargyl groups can form triazole linkage with azide-bearing compounds or biomolecules via copper catalyzed Click Chemistry. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

The Lactose/Galactose (Rapid) test kit is used for the rapid test of lactose, D-galactose and L-arabinose in food and plant products. Galactose dehydrogenase can be used the measurement and analysis of both D-galactose and L-arabinose. Suitable for the analysis of lactose in “low-lactose” or “lactose-free” samples which contain high levels of monosaccharides. The reagents provided in this kit are also suitable for use with AOAC method 2006.06 – Lactose in milk.
Note for Content: The number of manual tests per kit can be doubled if all volumes are halved. This can be readily accommodated using the MegaQuantTM Wave Spectrophotometer (D-MQWAVE).

These kits are designed for the rapid preparation of plasmid DNA from Escherichia coli.
Plasmid MiniPrep Kit
This kit is designed for the rapid preparation of plasmid DNA from small cultures of Escherichia coli using convenient spin columns. The plasmid DNA is preferentially purified from other cellular components such as genomic DNA and RNA. This kit is able to purify plasmids up to 13,000 bp in size, and the typical purification yield is up to 20 μg from 1.5 mL of bacterial culture. Purified DNA is of excellent quality for transformation, restriction enzyme digestion, sequencing and more. Also available in a 96-well format.
Plasmid MiniPrep Kit (Magnetic Bead System and High Throughput Magnetic Bead System)
Norgen’s Plasmid MiniPrep Kit (Magnetic Bead System) is designed for the rapid preparation of plasmid DNA from small batch cultures of Escherichia coli. Norgen’s magnetic beads bind DNA under optimized salt concentrations and release the bound DNA under low salt and slightly alkali conditions. The plasmid DNA is preferentially purified from other cellular components such as genomic DNA and RNA. The purified plasmids are fully digestible with all restriction enzymes tested, and are completely compatible with real-time PCR and NGS.
Norgen’s Plasmid MiniPrep Kit (Magnetic Bead System) is also available in a 96-well (HT) format for high throughput applications. Purification with the 96-well plates can be integrated with a robotic automation system.
Plasmid MaxiPrep Kit
This kit is designed for the rapid spin column preparation of plasmid DNA from up to 100 mL of Escherichia coli cultures. The kit allows for the isolation of plasmid DNA with final endotoxin levels of 0.1 EU/µg of DNA or less. The kit is able to purify plasmids up to 13,000 bp in size, and typical yields from a 100 mL culture for a high copy number plasmid are between 0.4 and 1.0 mg. The purified DNA is fully digestible with all restriction enzymes tested, and is completely compatible with manual or automated sequencing to achieve 95-100% accuracy.
