Propargyl-PEG3-CH2CO2H is an PEG linker with an alkyne and carboxylic acid set of functional groups. The alkyne group can participate in copper catalyzed azide-alkyne Click Chemistry to form a stable triazole linkage. The carboxylic acid can react with primary amines to form stable amide bonds; activator (e.g. EDC, or HATU) is needed.

Description
The DM4160 FluoroBand™ XL 25 kb Fluorescent DNA Ladder is a ready-to-use DNA ladder, which is pre-mixed with high sensitivity DNA binding fluorescent dye and loading dye for direct gel loading. The DNA Ladder DM4160 is composed of 14 individual DNA fragments: 25k, 10k, 8k, 6k, 5k, 4k, 3k, 2.5k, 2k, 1.5k, 1k, 750, 500, and 250 base pairs derived from a mixture of PCR products and specifically digested plasmid DNA; these bands can be visualized when illuminated with 470 nm blue light or UV light. 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. Real time observation of the electrophoresis is also possible if compatible light source is fitted to the electrophoresis tank.

Description
The SMOChem™ Deoxynucleotide (dNTP) Mix is an aqueous solution that contains an equimolar solution of ultrapure dATP, dCTP, dGTP and dTTP, each at a concentration of 25 mM at pH 8.5. The dNTP Mix is designed for many different molecular biology applications that involved in DNA synthesis or labeling, such as PCR, real-time PCR, DNA sequencing, reverse transcription, primer extension, and etc. The dNTP Mix is free of exo-deoxyribonuclease and endo-deoxyribonuclease as well as ribonuclease activity. The dNTP Mix offers the possibility to reduce the number of pipetting steps and the risk of reaction set up errors.
