SARS-CoV-2+Influenza A+B Antigen Assay

Diazo Biotin-PEG3-alkyne is useful for introducing a biotin moiety to azide-containing biomolecules using Cu(I)-catalyzed Click Chemistry. The hydrophilic spacer arm provides better solubility to the labeled molecules in aqueous media. Diazo allows efficient release of captured biotinylated molecules from streptavidin using sodium dithionite (Na2S2O4). Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

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.

Bis-Sulfone-PEG9-DBCO is a bis-alkylating labeling reagent that is selective for the cysteine sulfur atoms from a native disulfide. These reagents undergo bis-alkylation to conjugate both thiols derived from the two cysteine residues of a reduced native disulfide bond such as the interchain disulfide bonds of an antibody. The reaction results in covalent rebridging of the disulfide bond via a three carbon bridge leaving the protein structurally intact. Reagent grade, for research purpose.
