Propargyl-PEG13-t-butyl ester enables Click Chemistry reactions with azide-bearing compounds or biomolecules to form stable triazole linkages; copper is required as a catalyst. The t-butyl protection can be removed under acidic conditions. The PEG units improve the hydrophilicity of the molecule in aqueous media. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

Product Info
Description
The DM3100 ExcelBand™ 1 KB (0.25-10 kb) DNA Ladder is a ready-to-use DNA ladder, which is pre-mixed with loading dye for direct gel loading. The DNA ladder DM3100 is composed of 13 individual DNA fragments: 10k, 8k, 6k, 5k, 4k, 3k, 2.5k, 2k, 1.5k, 1k, 750, 500, and 250 bp derived from a mixture of PCR products and specifically digested plasmid DNA. This product contains two enhanced bands (3 kb and 1 kb) for easier reference. In addition, two tracking dyes, Xylene cyanol FF and Bromophenol blue which mimic the migration of 4,000 bp and 500 bp dsDNA during electrophoresis are also added for real time monitoring.
Features
