NH-bis(PEG2-propargyl)

t-Boc-N-Amido-PEG7-propargyl is a crosslinking reagent that enables the formation of triazole linkage with azides under the catalyzation of copper. The Boc-protected amine can be deprotected under mild acidic conditions. By introducing PEG chain into the molecule, the hydrophilicity can be greatly improved. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

DBCO-PEG5-NHS Ester is a DBCO-containing PEG linker containing NHS ester that can react specifically and efficiently with primary amines (e.g. the side chain of lysine residues or aminosilane-coated surfaces) at neutral or slightly basic condition to form a covalent bond. PEG5 spacer increases the water solubility of compounds in aqueous media. DBCO is commonly used for copper-free Click Chemistry reaction. Reagent grade, for research purpose.

Overview

• Simultaneous concentration, desalting and buffer exchange of total urinary proteins
• No molecular weight cutoff allows for isolation of all sizes of proteins and peptides
• Purification is based on spin column chromatography that uses Norgen’s resin separation matrix

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.
