Thermo Fisher Scientific Pierce Intact Protein Standard Mix, 1 x 76 ug

Thermo Scientific™ Pierce™ Intact Protein Standard Mix

The Thermo Scientific Pierce Intact Protein Standard Mix is a high-quality mixture of recombinant proteins used as a quality control standard for LC, LC/MS, LC/MS method development, and intact protein mass measurements.

주요 특징

• Verified protein sequences — Protein sequences confirmed by MS with average and monoisotopic masses corresponding to each provided sequence
• Recombinant — Proteins expressed in E. coli and B. subtilis; no bovine sources
• Compatible — Designed for QC over a wide range of molecular weights (10–70 kDa) and m/z distribution (600–1500 m/z)
• Flexible — Suitable for LC, LC-MS, and direct infusion methods
• Stable — Provided in a stable lyophilized format

제품 설명

This mixture contains six highly pure recombinant proteins, including:

• Human IGF-1 LR3
• Human thioredoxin
• Streptococcus dysgalactiae Protein G
• Bovine Carbonic Anhydrase II
• Streptococcus Protein AG (chimeric)
• Escherichia coli Exo Klenow

These proteins were selected for their broad molecular weight range, m/z distribution, and MS fragmentation characteristics. After expression and purification, they are optimally mixed and lyophilized for stability and convenience.
Each vial contains 76 μg of lyophilized protein mixture and does not contain salts or detergents.

Applications

• Qualitative LC
• LC/MS standardization and method development
• LC/MS intact protein mass measurement and top-down method development
• Digestion protocol optimization
