Methyltetrazine-PEG5-DBCO is a TCO reactive reagent with a DBCO group and water-soluble PEG spacer. This reagent can be used to convert azido-containing peptides or proteins into tetrazine-modified peptides or protein without catalyst or axillary reagents. DBCO is commonly used for copper-free Click Chemistry reactions. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

Description
The DM5100 ExcelBand™ Super Range DNA Ladder is a ready-to-use DNA ladder, which is pre-mixed with loading dye for direct gel loading. The DNA Ladder DM5100 is composed of 26 individual DNA fragments: 25k, 10k, 8k, 6k, 5k, 4k, 3k, 2.5k, 2k, 1.5k, 1.2k, 1k, 900, 800, 700, 600, 500, 450, 400, 350, 300, 250, 200, 150, 100 and 50 base pairs derived from a mixture of PCR products and specifically digested plasmid DNA. This product contains four enhanced bands (3k, 1.2k, 500 and 200 bp) for easier reference. In addition, three tracking dyes, Xylene cyanol FF, Bromophenol blue and Orange G which mimic the migration of 4,000 bp, 500 bp and 50 bp dsDNA during electrophoresis are added for real time monitoring.
