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.

endo-BCN-PEG4-acid is a click chemistry reagent with a BCN group witha terminal carboxylic acid (CO2H). The terminal carboxylic acid is reactive with primary amine groups in the presence of activators (e.g. EDC, or HATU) to form a stable amide bond. The BCN group can react with azide -tagged compound or biomolecules. The hydrophilic PEG spacer increases solubility in aqueous media. Reagent grade, for research purpose.

Everything you need to run a trial PACE Genotyping Reaction on your existing lab equipment. Each PACE Trial Kit includes Test DNA samples, PACE Genotyping Assays, PACE Master Mix and a comprehensive PACE Genotyping Trial Kit Manual.
Everything you need to run a trial PACE® allele-specific PCR Genotyping Reaction on your existing lab equipment. Each PACE Trial Kit includes Test DNA samples, PACE Genotyping Assays, PACE Master Mix and a comprehensive PACE Genotyping Trial Kit Manual.
Anyone who wants to try PACE genotyping reagents in their lab for the first time with a set of validated DNA samples, SNP assays and PACE Master Mix.
Step 1. Dispense each of the three trial DNA samples (DNA 1, 2 and 3) plus water (No Template Control) in triplicate onto a PCR plate using the suggested volumes.
Step 2. Combine appropriate volumes of PACE Genotyping Master Mix with PACE Genotyping Assay in a tube, as directed, then mix.
Step 3. Dispense the combined mixtures into each of the wells containing DNA using volumes indicated. Each test now contains a complete PACE Genotyping Reaction.
Step 4. Seal your PCR plate with an optically clear seal and centrifuge to ensure all components are at the bottom of the wells.
Step 5.Thermally cycle the reaction plate using the thermal cycling conditions provided.
Step 6. Read the plate and compare data produced with the expected results provided in the manual. Simple!
