Introduction
Intended Use
For the enumeration of enterococci in water and other liquids by the membrane filtration technique.
Principle and Interpretation
The growth of the entire accompanying Gram-negative microbial flora is inhibited by sodium azide. Enterococci reduce 2,3,5-Triphenyl tetrazolium chloride (TTC) to give a red formazan inside the bacterial cell, their colonies are thus red. Nitrogen, minerals, and amino acids are provided by the tryptose whilst yeast extract supplies vitamins. Glucose acts as the carbon source, dipotassium phosphate buffers the medium, and agar-agar is the solidifying agent.

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.
*Yield will depend on the health status of the donor.
Storage Conditions and Product Stability
All solutions should be kept tightly sealed and stored at room temperature. Once opened, the solution should be stored at 4°C. This kit is stable for 2 years after the date of shipment.

Propargyl-PEG14-acid is an alkyne reagent with a carboxylic acid. The carboxylic acid can form amide bonds with amines under the activation of EDC or HATU. The alkyne group can react with azides through Click Chemistry reaction to form triazole linkage. The PEG spacer increases the solubility of the molecule in aqueous environment. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.
