High-Purity Bovine Albumin (BSA) CAS 9048-46-8 Bulk Supply: The Ultimate B2B Sourcing Guide for Laboratories & Diagnostic Manufacturers
Bovine albumin CAS 9048-46-8
In the fields of biotechnology, clinical diagnostics, and pharmaceutical manufacturing, consistency is everything. A single trace impurity or batch-to-batch variation in your raw materials can ruin months of cell culture or cause critical errors in diagnostic assays.
As a premier, audited Bovine Albumin factory supplier, we manufacture high-purity Bovine Serum Albumin (BSA) designed to meet the strict standards of global life science industries. This comprehensive guide outlines our technical specifications, processing technology, and bulk supply chain capabilities.
Name: Methyl L-Prolinate Hydrochloride
CAS: 2133-40-6

Product Overview: What is Bovine Albumin?
Bovine Albumin (CAS Number: 9048-46-8), universally known as Bovine Serum Albumin (BSA), is a single-chain globular protein extracted from bovine plasma. It is highly valued in scientific applications for its stability, lack of enzymatic activity, and ability to act as a natural transport protein.

- Physical Appearance: Off-white to light yellow, free-flowing lyophilizate powder or flakes
- Purity (Electrophoresis): (≥ 98.0%) up to \(≥ 99.0%) based on application grade
- pH Range (10% water solution): 6.5 – 7.5
- Moisture Content: (≤ 5.0%)
- Available Product Variations:
- Diagnostic Grade (Protease-free, low IgG)
- Standard Fraction V Grade (Biochemical reagent use)
- Cell Culture Grade (Endotoxin-tested, fatty-acid free or fatty-acid ultra-low)
Application
Bovine Albumin is one of the most widely used proteins in modern biotechnology due to its versatile structural properties.
Clinical Diagnostics & Immunoassays
BSA serves as an essential blocking agent in enzyme-linked immunosorbent assays (ELISA), Western blots, and immunohistochemistry. It coats binding sites on plastic plates and membranes, preventing non-specific background binding and ensuring highly accurate diagnostic readings.
Cell Culture & Vaccine Manufacturing
In serum-free media formulations, Bovine Albumin acts as a carrier for essential lipids, hormones, and micronutrients that cells need to grow. It stabilizes fragile proteins in the media and neutralizes toxic heavy metals or free radicals.
Pharmaceutical Formulations
Because of its stable structure, BSA is frequently used as an excipient or stabilizing vehicle for delicate protein therapeutics, enzymes, and antibody formulations during long-term storage.
FAQ
Q: What is the verified shelf-life of your lyophilized Bovine Albumin?
When stored sealed in its original container at 2°C to 8°C and protected from ambient moisture, our BSA powder is guaranteed to maintain its complete technical specifications for 36 months from the date of manufacture.
Q: How do you guarantee your product is free from protease or IgG contamination?
Our diagnostic-grade processing line utilizes specific heat-fractionation steps and rigorous chromatographic refinement to selectively strip out residual globulins and enzymes. Every diagnostic batch is verified protease-free before release.
Q: What is your Minimum Order Quantity (MOQ) for bulk contract pricing?
While we can provide small 1kg sample packages for initial laboratory validation, our standard industrial contract pricing begins at a minimum volume of 25kg.
Advanced Production Technology
Our facility does not rely on outdated, high-heat precipitation methods that alter protein structures. Instead, we use an advanced combination of heat-shock isolation and continuous multi-stage ultrafiltration.

[Finished High-Purity BSA Powder]
By keeping processing temperatures low and using a closed-loop system, we preserve the protein’s natural conformation. This advanced filtration also removes unwanted immunoglobulins (IgG), heavy metals, and fatty acid residues, resulting in a highly soluble, ultra-pure final product.
Product Advantages: Compared with Competitors
When comparing wholesale chemical and biological vendors, biological safety and purity are critical. Our Bovine Albumin stands out from trading company stocks in several key areas:
- Complete Traceability: Every gram of our BSA is processed from plasma collected at government-inspected facilities located in verified, disease-free geographical regions (free from BSE/TSE).
- Excellent Solubility & Clarity: Our lyophilized powder dissolves rapidly in water or balanced salt solutions without leaving cloudy residues or persistent foam, which can interfere with automated diagnostic pipetting.
- Ultra-Low Endotoxin Levels: Our cell culture grade options maintain endotoxin levels below 1.0 EU/mg, preventing unexpected cell activation or death in sensitive bioreactors
Factory Scale & Analytical Capabilities
We run a fully integrated bio-fractionation plant engineered for large-scale, continuous B2B delivery:
- Production Capacity: Our facility features an annual lyophilization output of 100 Metric Tons, allowing us to reliably fulfill large contract orders.
- Stringent Regulatory Compliance: Our plant operates under strict ISO 9001 and ISO 22716 quality frameworks. We provide complete documentation for regulatory audits.
- Advanced In-House Testing: Every batch undergoes rigorous quality control testing, including agarose gel electrophoresis for purity, FPLC for monomer content, and chromogenic LAL assays for precise endotoxin measurement.
Industrial Packaging, Sealing & Global Freight Logistics
Because Bovine Albumin is a natural macromolecular protein, it must be protected from moisture and heat during transit to prevent degradation.
Industrial Packaging Configurations
- HDPE Laboratory Jars: 100g, 500g, or 1kg jars sealed with induction liners for pilot development.
- Bulk Fiber Drums: 10kg or 25kg double-lined food-grade polyethylene bags enclosed in durable fiberboard outer drums for industrial manufacturing lines.
Shipping & Receiving Protocols
We ship globally using verified cold-chain and temperature-controlled air or sea freight channels (FOB, CIF, or DDP terms). While lyophilized BSA powder is relatively stable at ambient temperatures for short periods, we ship bulk orders with desiccant packs and temperature indicators. Upon receiving your shipment, your warehouse team should inspect the tamper-evident seals and immediately transfer the drums to a clean, climate-controlled cold storage environment held between 2°C and 8°C.
