A Superior Alternative to Traditional BSA
In life sciences and biotechnology, recombinant Bovine Serum Albumin (rBSA) has become a preferred alternative to traditional animal-derived BSA, particularly in diagnostic and research assays. Produced through heterologous expression in yeast cells, rBSA offers enhanced purity, consistency, and performance, making it ideal for applications such as ELISA, Western blotting, immunohistochemistry (IHC), lateral flow assays, and CLIA.
Why Choose rBSA as a Blocking Agent?
Blocking agents are essential in immunoassays and molecular biology applications to prevent non-specific binding and enhance signal clarity. Levprot Bioscience’s rBSA outperforms conventional BSA, offering:
- Superior Performance: More efficient in preventing non-specific adhesion of enzymes to plastic surfaces and stabilizing proteins during incubation.
- Higher Consistency & Homogeneity: Eliminates batch-to-batch variability commonly found in animal-derived BSA.
- Ethical & Safety Advantages: Completely animal-free, reducing the risk of pathogen contamination and meeting regulatory requirements for ethical sourcing.
- Optimized Efficiency: Between 20 and 100 times more effective as a blocking agent, requiring significantly lower concentrations compared to traditional BSA.

Key Applications of rBSA as a Blocking Agent
- ELISA (Enzyme-Linked Immunosorbent Assay): Provides a more uniform coating, ensuring higher signal clarity and reproducibility.
- Western Blotting: Effectively prevents non-specific interactions, improving the specificity of antibody-antigen detection.
- Immunohistochemistry (IHC): Reduces background staining, improving tissue visualization.
- Lateral Flow Assays & CLIA: Enhances signal stability in rapid diagnostic platforms.
- Molecular Biology & Cell Culture: Serves as a stabilizing agent for proteins and enzymes, improving reaction efficiency.
Optimized Use and Storage Conditions
- Recommended Dilution: Due to its higher blocking efficiency, rBSA should be diluted 1:20 to 1:100 when replacing conventional BSA.
- Storage:
- Liquid Formats: Store at -80°C or -20°C for long-term stability.
- Lyophilized rBSA: Can be stored at room temperature or reconstituted for long-term use.
- Short-Term Storage: 4°C storage is possible, but multiple freeze-thaw cycles should be avoided.
- Buffer Composition: rBSA is available in optimized formulations, including Tris-based buffers with KCl and EDTA, with or without glycerol for added stability.
