Intact mAb Mass Check Standard
Fully characterized monoclonal antibody standard
Analyzing intact proteins by mass spectrometry (MS) is a powerful approach for protein identification, mAb characterization, and assignment of protein modifications.
The Intact mAb Mass Check Standard is a LC-MS reference standard used as a qualitative tool for intact mass analysis. With this standard, you can more easily and efficiently achieve your routine MS optimization, system setup and performance testing requirements – ensuring that the MS instrument is tuned and calibrated.
Intact mAb Mass Check Standard
Specifications
Overview
- Intact mouse IgG1 protein purified by Protein-A with a known molecular weight
- Used as the unlabeled, control/reference standard for the GlycoWorks RapiFluor-MS N-Glycan sample preparation workflow as it has 4 major glycosylated peptides
- Provided in a Waters TruView Vial (ideal for peptides) as 1 mg of lyophilized solid (lyophilization grade sucrose is used for stabilization)
Recommended Use: For higher molecular weight intact mass measurements.
