Specially Formulated

Waters MassPrep™ Protein Standard Mixes are specially formulated and designed to  aid in the evaluation and benchmarking of columns for protein separation.

Waters line of Protein Standards provide:

  • Consistent Chromatography:  Recommended to be used on a regular basis for monitoring column and system performance.
  • Quality:  Manufactured with strict quality control for batch-batch reproducibility
  • Ease of Use:  Packaged in Waters Vials for direct solubilization

Reversed-Phase Protein Separations: The MassPREP Protein Standard Mix

This intact protein validation mix is designed for verification of HPLC/UPLC® instruments. This standard is also used to evaluate the performance of columns used for protein analysis, specifically the ACQUITY UPLC® and XBridge® Protein BEH C4300Å Columns. The MassPrep Protein Standard  contains proteins that have a wide range of isoelectric points, molecular weights, and hydrophobicities.  

 

Size Exclusion Separations: SEC Protein Standard Mixes

Whether using UPLC or HPLC, the SEC Protein Standard Mixes are unique, specially formulated protein mixtures specific to the BEH 200Å, BEH 125Å or BEH 450Å columns.  It is recommended that they be used on a regular basis for evaluation of these types of columns for optimal system performance.

 

Ion Exchange Separations: IEX Test Standards

These standards are specially designed for either Cation or Anion exchange chromatography and each provide a unique set of 3 proteins found to provide good chromatographic separation based on the charge state being utilized.

 

Hydrophobic Interaction Chromatography: HIC Protein Standard Mix

This six intact protein mix,  is a comprehensive protein mix that provides good chromatographic separation and gradient range. Allowing you to benchmark a new column, develop a method or troubleshoot system and column issues.

System Check: Complex Protein Standards

Analysis of intact proteins by MS is a powerful approach for protein identification and assignment of protein modifications. The Intact mAb Mass Check Standard is a LC-MS standard used as a qualitative tool for intact mass analysis. This standard is designed to be used for routine MS optimization, system setup and performance testing. It is an intact mouse IgG1 protein purified by Protein-A with a known molecular weight, ideal for higher molecular weight intact mass measurements.  It is provided in a Waters TruView™ Vial (ideal for peptides) as 1 mg of lyophilized solid (lyophilization grade sucrose is used for stabilization). Recommended solubilization is in 100ul-200ul of DI water.  Store at -20 °C immediately upon arrival.
