N-(Propargyl-PEG2)-DBCO-PEG3-Amine, TFA salt enables formation of triazole linkage with azide-bearing compound via copper catalyzed Click Chemistry. The amine group is reactive with carboxylic acids, activated NHS esters, carbonyls (ketone, aldehyde), etc. The propargyl group can be linked to azide-containing biomolecules via Click Chemistry. Reagent grade, for research purpose.

These kits concentrate urine proteins while simultaneously removing salts, urea, and other urine contaminants. There is no molecular weight cut-off and therefore the columns capture total urinary proteins and peptides of all sizes making them ideal for biomarker discovery work, differential expression of proteins in various diseases, or other diagnostic research. The columns are convenient, rapid and easy to use and thus offer significant time savings over classic dialysis protocols. The resulting high-quality protein sample is concentrated and free from the original sample salts, thus preparing the sample conveniently for downstream proteomic applications including SDS-PAGE, 2D Gels, MALDI-TOF, LC/MS, LC/MS/MS, whole protein mass spectrometry, western blotting, protein microarrays, and more.
ProteoSpin™ Urine Protein Concentration Micro Kit
Each spin column is able to concentrate and desalt up to 200 μg of urine proteins. Twelve samples can be processed in 20 minutes.
ProteoSpin™ Urine Protein Concentration Midi Kit
The ProteoSpin™ Urine Protein Concentration Midi Kit provides a fast and simple procedure for concentrating dilute solutions of urine proteins from 1 to 5 mL inputs of urine. Each mini spin column is able to concentrate and desalt up to 3 mg of urine proteins in 30 minutes.
ProteoSpin™ Urine Protein Concentration Maxi Kit
The ProteoSpin™ Urine Protein Concentration Maxi Kit provides a fast and simple procedure for concentrating dilute solutions of urine proteins from 2 to 20 mL inputs of urine. Each maxi spin column is able to concentrate and desalt up to 4 mg of urine proteins in 45 minutes.

N-(Aminooxy-PEG2)-N-bis(PEG3-propargyl) consists of two terminal propargyl groups and an aminooxy group. The propargyl groups reacts with azide-bearing compounds or biomolecules via copper catalyzed Click Chemistry. The aminooxy group is reactive towards aldehydes to form oxime bonds. If a reductant is used, it will form a hydroxylamine linkage. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries. Aminooxy compounds are very reactive and sensitive; they cannot be stored for long term. Immediate use (within 1 week) is highly recommended.
