Protexpert™ (Art.: PROE) is a 10% aqueous protein solution composed of highly purified porcine-derived dermal polypeptide fragments. It exhibits excellent and highly efficient protein-stabilizing properties. The product is free from nucleic acids, polysaccharides, lipids, and any additives, and presents no risk of cross-reactivity.
Protexpert™ can serve as an alternative to Bovine Serum Albumin (BSA) with minimal batch-to-batch variation.
Protexpert™ 10%
Product Overview
Protexpert™ is a 10% aqueous protein solution composed of highly purified porcine-derived dermal polypeptide fragments. It exhibits excellent and highly efficient protein-stabilizing properties. The product is free from nucleic acids, polysaccharides, lipids, and any additives, and presents no risk of cross-reactivity. As a highly effective protein stabilizer, it offers the following key features: effectively improves the stability of bioactive proteins; enhances stability during lyophilization and heat treatment; and extends the shelf life of enzymes and proteins. Protexpert™ can serve as an alternative to Bovine Serum Albumin (BSA) with minimal batch-to-batch variation. It is widely used as a stabilizer for lyophilized or liquid protein formulations, a blocking agent for coating surfaces, and a stabilizer for calibration/control materials and magnetic bead-conjugated antibodies.

Instructions for Use
Protexpert™ 10% does not contain preservatives. If the entire product cannot be used within 24 hours, it is recommended to aliquot it into smaller portions and store them frozen (-20°C) for long-term preservation after first use.
To prevent microbial contamination, a preservative can be added after opening to inhibit microbial growth and contamination (e.g., 0.1% ProCide 300 or 0.2% ProCide 950 is recommended), and the solution should be stored at 2–8°C.
For research use only or for further use in the production of detection kits. Not for human or animal use!
Q1: What does ImmuTruster do in an immunoassay?
A: ImmuTruster formulations improve assay sensitivity and signal-to-noise by stabilizing immune complexes and reducing non-specific interactions in the reaction system.
Q2: How do ImmuTruster, ImmuOptimizer and ImmuTruster Plus differ?
A: They are three formulations of the same platform tuned for different assay matrices - screen them in parallel on your system and select by sensitivity gain and background level.
Q3: What is Protexpert 10%?
A: Protexpert 10% is a ready-to-use 10% aqueous protein solution with highly efficient protein-stabilizing properties, free from nucleic acids, polysaccharides, lipids and additives - suited to stabilization of sensitive IVD reagents including freeze-drying applications.
Q4: Can these products be used in automated CLIA platforms?
A: Yes. They are liquid, ready-to-use components that can be introduced as formulation additives or diluents after compatibility validation on your platform.
