  • Lifetime is based on laboratory tests. Actual data is according to sample properties.
  • PS/DVB: Poly(styrene/divinylbenzene)

Advantages of Absolut A

  • Mono-dispersed PS/DVB particles feature very high rigidity, low back pressure, and quick mass transfer.
  • Unique hydrophilic surface treatment technology minimizes the nonspecific absorption and guarantees accurate determination of antibody concentration.
  • The protein binds specifically to the Fc region of IgG, and the high selectivity guarantees the accuracy of concentration determination.
  • Fast analysis cycle time: 2 – 5 minutes.
  • Satisfactory linearity within a wide concentration range from 0.02 to 10 mg/ml.
  • Long lifetime: 3000-5000 analysis cycles.
  • New alkali-resistant Protein A ligand warrants 0.1-0.5M NaOH cleaning conditions.
