General description

Protein determination is one of the most common operations performed in biochemical research. Total protein kit, micro provides a simple, rapid, and highly sensitive method requiring only 50 μL or less sample.

Application

Total protein kit, micro has been used to determine:
  • total protein in the bacterial homogenate by Bradford method
  • total protein content by the Bradford microassay from the tissue extracts
  • serum total protein
  • soluble protein content by the Bradford method from leaves

Biochem/physiol Actions

Total protein kit, micro can be used to determine the concentration of proteins in solution.

Suitability

Suitable for protein determination for samples of up to 0.5 mg/ml.

Principle

Brilliant blue G (Coomassie blue) reacts with protein in an acid-alcohol medium to form a blue-colored protein dye complex. The color, measured at 595 nm, is proportional to the protein concentration.

Testing Method

Colorimetric, Endpoint
