PEG3-bis(Amino-Tri-(Propargyl-PEG2-ethoxymethyl)-methane) is a crosslinker consisting of six propargyl groups. The propargyl groups can form triazole linkage with azide-bearing compounds or biomolecules via copper catalyzed Click Chemistry. The hydrophilic PEG spacer increases solubility in aqueous media. Reagent grade, for research purpose.

Protein A Colloidal Gold for Lateral Flow (1mL)
Product image shows functional testing of Protein A 40nm colloidal gold on a lateral flow test. Protein A 40nm colloidal gold was incubated in lateral flow running buffer alone or in the presence of a limiting amount of monoclonal antibody that targets the chemical-BSA conjugate. The gold was then applied to the sample port of a cassette containing a lateral flow strip sprayed with a chemical conjugate (Chemical-BSA) on the test line and a goat anti mouse antibody as the control line. The data demonstrates the specificity and robustness of the Protein A 40nm colloidal gold.
Our products are produced in a state-of-the-art manufacturing facility that enable rapid turnaround times while ensuring batch to batch consistency and reliability.
Functionally tested Protein A conjugated gold
Perfect for Lateral Flow Development and use in final product
40nm gold particles conjugated to Protein A are offered in 10 OD 1mL size. If a different OD or amount is required please

The hydrogen peroxide Assay Kit provides a simple robust method for the measurement of hydrogen peroxide. This kit utilizes a highly sensitive Megaplex Red probe which in the presence of horseradish peroxidase (HRP), allows for the measurement of H2O2 in a sample. Upon oxidation of the probe by HRP, a coloured product (resorufin) is formed that can be measured in fluorescence mode using excitation in the range 530-560 nm and emission at ~ 590 nm or colourimetrically at 570 nm. The excitation and emission maxima of Megaplex Red are 571 nm and 585 nm respectively.
