The Thermo Scientific™ Pierce™ BSA Protein Digest Standard, LC-MS Grade, is a validated protein digest optimized for use as a quality control sample for liquid chromatography (LC) and mass spectrometry (MS) analysis of proteomic samples.

Positive control sample—BSA digest optimized and validated as a quality control standard for mass spectrometry applications
Excellent sequence coverage—greater than 85% sequence coverage
Validated peptide quality—digestion procedure optimized for minimal missed cleavages and over-alkylation
Rigorously tested—high-quality, consistent BSA protein digest documented via lot-specific certificates of analysis
Stable—provided in a stable lyophilized format

The Pierce BSA Protein Digest Standard is produced using high quality bovine serum albumin (BSA) and mass spectrometry-grade trypsin. The BSA is fully reduced, alkylated (iodoacetamide), and desalted (C18) after trypsin digestion to provide a quality LC/MS-grade standard that is free of intact protein. The peptide digest standard provides excellent sequence coverage with minimal over-alkylation and missed cleavages. This digest standard has been robustly tested for peptide quality, digestion efficiency, and lot-to-lot uniformity and is suitable for LC and LC-MS applications.

Frequently asked questions (FAQs)

Several technical replicate injections of a known standard sample, e.g., Pierce BSA Digest (Cat. No. 88341), Pierce 6 Protein Digest (Cat. No. 88342), or Pierce HeLa Protein Digest Standard (Cat. Nos. 88328, 88329) should be used to equilibrate and compare the new column to reference chromatograms.

The best way to assess the performance of an entire LC-MS system is using a mass spectrometry calibration solution, peptide retention time standards (Pierce Peptide Retention Time Calibration Mixture (PRTC), Cat. No. 88321 and Pierce LC-MS/MS System Suitability Standard (7 x 5 Mix), Cat. No. A40010), and a known standard sample, e.g., Pierce BSA Digest (Cat. No. 88341), Pierce 6 Protein Digest (Cat. No. 88342), or Pierce HeLa Protein Digest Standard (Cat. Nos. 88328, 88329) specific to your application. We recommend frequent assessment of LC-MS system performance on a routine basis to compare results over time.

Here are our recommendations:

- Pierce Peptide Retention Time Calibration Mixture (Cat. No. 88321) for LC system and gradient optimization
- Pierce BSA Protein Digest, MS grade (Cat. No. 88341), Pierce 6 Protein Digest, equimolar, LC-MS grade (Cat. No. 88342), and Pierce HeLa Protein Digest Standard (Cat. Nos. 88328, 88329) for "bottom up" LC-MS method optimization and LC-MS suitability assessment
- Pierce LC-MS/MS System Suitability Standard (7 x 5 Mix) (Cat. No. A40010) for assessing the gradient, sensitivity, and dynamic range of the LC-MS system for discovery and targeted peptide quantitative workflows
- Pierce TMT11plex Yeast Digest Standard (Cat. Nos. A40938, A40939) for assessing system performance for TMT-based quantitative workflows
- Pierce Intact Protein Standard Mix (Cat. Nos. A33526, A33527) for "top down" LC-MS method optimization and LC-MS suitability assessment
