Aluminum Block Set

Propargyl-PEG4-methylamine is a PEG linker that can be react with azide compounds in copper catalyzed azide-alkyne Click Chemistry reactions. The methylamine group is reactive with carboxylic acids, activated NHS esters, carbonyls (ketone, aldehyde) etc. The PEG spacer increases hydrophilicity of the linker in aqueous environment. 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.

Description

Microcystin are a class of hepatotoxins produced by blue-green algae such as Microcystis aeruginosa.  Microcystin-LR is the most common of the over 50 different congeners. Cyanobacteria can produce microcystin in large quantities during an algae bloom which then pose a major threat.

This kit can be used for quantitative test of Microcystin in liquid samples such as water, wastewater, algal cultures, and solid samples such as fish.
