Protein Carbonyl Assay Kit

The BioCell Protein Carbonyl Assay Kit is an enzyme - linked immuno-sorbent assay (ELISA) for the measurement of protein carbonyls in biological samples.

Protein carbonyls are formed through oxidation of proteins by a variety of mechanisms. They are sensitive markers of oxidative injury.

Key Benefits:

  • Measures carbonyls quantitatively
  • Requires only microgram amounts of protein
  • Has a very low non-specific background
  • Is highly sensitive for analysing clinical samples
  • Correlates well with the colorimetric assay
  • Is easier to use, a lot less labor-intensive and can handle more samples per day than the colorimetic assay

Assay Principle:

Protein samples are reacted with DNP then nonspecifically adsorbed to an ELISA plate. Free DNP and nonprotein constituents are easily washed away, giving minimal interference.

The adsorbed protein is reacted with a biotinylated anti-DNP antibody    

followed by streptavidin-biotinylated horseradish peroxidase. Absorbances are related to a standard curve prepared from serum albumin containing increasing proportions of HOCl-oxidized protein.

How the Kit Works:

  • Standards, control samples, all reagents, detailed instructions and plate are supplied.
  • Up to 81 samples can be analysed in single analyses, although duplicate or triplicate analysis is recommended for best results. The kit components can be used more than once, permitting the analysis of fewer samples at a time without using up the entire kit at once.
  • Carbonyl concentrations are calibrated against a protein that has been oxidized and standardized colorimetrically.

Stability:

The reagents in this kit will be stable for at least six months if stored as indicated.

PC Kits do not require to be kept under cool conditions for short term transportation. The kits are stable at room temperature for up to 6 weeks.
