N-(t-butyl ester-PEG2)-N-bis(PEG2-propargyl) is a multi-functional PEG linker with two terminal propargyl groups and a t-butyl ester. The propargyl groups enables formation of triazole linkage with azide-bearing compounds or biomolecules in copper catalyzed Click Chemistry. The t-butyl protected carboxyl group can be deprotected under mild acidic conditions. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

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.
Sequentially purify total RNA (and miRNA), DNA and proteins from a single sample
No sample splitting or need to use phenol or precipitation methods
Purify RNA/DNA/Protein from cultured animal cells, tissues, blood, bacteria, yeast, fungi or plants
Purification is based on spin column chromatography that uses Norgen’s proprietary resin separation matrix
RNA/DNA/Protein Purification Plus Kit
This kit provides a rapid method for the high throughput isolation and purification of total RNA, DNA and proteins sequentially from a single sample of cultured animal cells, small tissue samples, blood, bacteria, or yeast. The kit employs two columns: 1) for gDNA purification and 2) for RNA purification utilizing Norgen’s resin columns (superior for the binding of all RNA sizes including miRNA). The proteins are also purified on the second column after RNA elution. The proteins are eluted in buffer and are ready for downstream application without any further clean up required. The proteins can be quantified directly, used in western blots, ELISA or mass spectrometry. This kit provides a rapid spin-column method for the isolation and purification of total RNA, genomic DNA and proteins sequentially from a single sample of cultured animal cells, small tissue samples, blood, bacteria, yeast, fungi or plants.
RNA/DNA/Protein Purification Plus Micro Kit
This kit provides a rapid spin-column method for the isolation and purification of total RNA, DNA and proteins sequentially from a single sample of cultured animal cells, small tissue samples, microdissected samples including LCM, stem cells, sorted cells, and CTC. The total RNA, genomic DNA and proteins are all column purified in less than 30 minutes. The RNA and DNA can be eluted in as little as 20 µL while the protein can be eluted in as little as 50 µL. This kit provides the same performance as if the samples were isolated from dedicated kits.
RNA/DNA/Protein Purification 96-Well Plus Kit
The kit employs two plates: 1) for DNA purification and 2) for RNA purification utilizing Norgen’s resin (superior for the binding of all RNA sizes including miRNA). Please see the protocol schematic below.
