Description
FluoroVue™ Nucleic Acid Gel Stain (10,000X) is specially designed for in-gel use and is a safer replacement for conventional Ethidium bromide (EtBr), which poses a significant health and safety hazard to its users. It is a fluorescent stain which offers highly sensitive detection of double-stranded or single-stranded DNA and RNA in a convenient manner. FluoroVue™ Nucleic Acid Gel Stain offers high sensitivity that is several times greater than EtBr.
FluoroVue™ Nucleic Acid Gel Stain is compatible with both conventional UV gel-illumination systems as well as harmless long wavelength blue light illumination systems, like B-BOX™. When bound to nucleic acids, FluoroVue™ Nucleic Acid Gel Stain has a fluorescent excitation maximum of 250 and 482 nm, and an emission maximum of 509 nm. Therefore, it can replace EtBr without the need of changing existing lab imaging systems.

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.

This kit provides a fast and simple procedure for the effective depletion of major serum proteins including albumin, α-antitrypsin, transferrin and haptoglobin from serum and plasma samples. Such abundant proteins usually obscure less abundant proteins in gel electrophresis making them difficult to visualize and recover. The kit reduces sample complexity to allow for convenient investigation of less abundant proteins. In other applications such as mass spectroscopy, fractionating abundant proteins improves the resolution of less abundant proteins. The kit is ‘generic’ in that it is not antibody-based and can thus be used to deplete abundant proteins from any starting material – human or various other animals – making it more versatile, flexible and affordable than other kits. Resulting proteins are ready for a range of applications including 2D gel electrophoresis, SDS-PAGE, Mass Spectrometry, Protein microarrays, DIGE (Difference Gel Electrophoresis) and more.
