950 mL

Thermo Scientific™ Pierce Dimethylsulfoxide (DMSO) is a sequencing-grade preparation with high purity and consistent absorptivity properties for use in HPLC and mass spectrometry methods.nn nnA sequencing-grade preparation with high purity for use in traditional amino acid analyzers and other high-volume applications.nnThis sequencing-grade dimethylsulfoxide is >99.5% pure DMSO. The economically priced 950mL bottles are an excellent choice for protein and peptide applications that requiring large volumes of the water-miscible solvent. The 50mL bottles are provide convenience and minimize waste for small dissolution and reaction volumes. The purity test ensures that preparation is essentially devoid of amines. The formulation was originally developed for peptide sequencing applications with amino acid analyzers, which required high purity solvent and an affordable price. This DMSO is packaged in solvent-rinsed amber glass bottles and sealed with PTFE-lined fluorocarbon caps for ultimate protection.

Measure protein concentration using a stable formulation of the original Bradford reagent described in the literature with Thermo Scientific™ Pierce Coomassie Protein Assay Kit.

The Pierce Coomassie Protein Assay Kit is a ready-to-use formulation of the popular assay reagent originally described by Bradford in 1976. When mixed with a protein solution, the acidic Coomassie-dye reagent changes color from brown to blue in proportion to the amount of protein present in the sample. Protein determinations are made by comparison to the color response of protein assay standards, usually prepared as a series of known dilutions of bovine serum albumin (BSA) or bovine gamma globulin (BGG). The kit includes Coomassie Protein Assay Reagent and a package of Albumin Standard Ampules. The simple procedure is adaptable to nearly any volume scale, including test tubes, cuvets and microplates.

Highlights:

• Bradford reagent – stable, ready-to-use kit of the classical Bradford assay reagent
• Colorimetric – measure with a standard spectrophotometer or plate reader (595nm)
• Easy to use – single reagent; no working reagent preparation required
• Fast – almost immediate color development; add, mix and read results
• Broad range – detects protein concentration in the range 1 to 1500μg/mL
• Flexible – microplate and cuvet protocols provided with the instructions and adaptable to several target working ranges

Includes:

Coomassie Protein Assay Reagent and 10 ampules of Albumin Standard
