maXis II LC-QTOF
Antibody Characterization

Charakterystyka przeciwciał - analiza nienaruszonych cząsteczek i podjednostek

Zwiększona rozdzielczość i dokładność masy dla większej pewności pomiarów podjednostek

[Bitte nach "Polish" übersetzen:] Enhanced resolution and mass precision - for highly precise and accurate determinations of the monoisotopic masses of both the Light and Heavy Chains of mAb's on an LC timescale for automated confirmation of product identity and detection of impurities. Superb raw data quality allows for fast and easy detection of modifications (including deamidation) in biotherapeutic characterization without the need for time and cost intensive digestion and peptide mapping of the entire antibody.

Complex Protein Mixture

Kompleksowa mieszanina białek

Doskonały zakres dynamiki (5 rzędów wielkości) do analizy złożonej mieszaniny białek

[Bitte nach "Polish" übersetzen:] The maXis II delivers superb dynamic range (5 orders of magnitude) at UPLC speeds enabling analysis of protein mixtures in complex, high-background matrices. For example > 1000 proteoforms resolved in a 35 min run from an undiluted serum sample.

 

  • • Sub-ppm mass accuracy & isotopic accuracy
  • • Isotopic resolution even for proteins > 40Kda
  • • MS/MS available for proteoform ID

Native Mass Spectrometry

Natywna spektrometria masowa (opcjonalnie)

Opcja High Mass (wysokich mas) umożliwia analizę natywnych kompleksów białkowych i ADC

[Bitte nach "Polish" übersetzen:] The High Mass Option combines adjustable Funnel 1 pressure with in-source CID on the maXis II to permit efficient desolvation and ionization of the native sprayed analyte without sacrificing other performance vectors. Thereby enabling easier application of native MS or high mass workflows for the structural investigation of larger proteins and/or protein complexes (including antibody drug conjugates).
