When shopping for bovine serum albumin (BSA) products, choose items intended for research or manufacturing use. This guide highlights five relevant options: three BSA powders for precise weighing and concentration control, plus two BSA-related solutions for dilution or standardization. Each product is best suited for experimental workflows like protein quantification, calibration, or sample stabilization. The following table provides quick references to the selected products for quick comparison.

|---|---|---|---|
| Albumin, Bovine Fraction V [BSA], 25 Grams | Powder | Small to mid-scale experiments; precise weighing | Powder form; not for food or drug use |
| Albumin, Bovine Fraction V [BSA], 100 Grams | Powder | Mid-scale protein work; convenient bulk | Powder form; not for food or drug use |
| Albumin, Bovine Fraction V [BSA], 1 Kilogram | Powder | Large-scale prep or long-term storage | Powder form; not for food or drug use |
| Bovine Serum Albumin Standard [2mg/ml] – Cepham Life Sciences | Liquid standard | Calibration and quantitative assays | Standard liquid; easy to use |
| Bovine Serum Albumin Solution, 20mg/ml Solution, 5 Milliliters | Liquid solution | Immediate dilutions and assay setups | Liquid; not for food or drug use |
Albumin, Bovine Fraction V [BSA], 25 Grams
Brand: RPI. Features: For research or further manufacturing use only; not for food or drug use. CAS number 9048-46-8; Common name BSA. Best for small-scale protein experiments where precise weighing of a dry powder is required. Limitation: powder must be stored properly to maintain stability; verify handling requirements before use.
Albumin, Bovine Fraction V [BSA], 100 Grams
Brand: RPI. Features: For research or further manufacturing use only; not for food or drug use. CAS 9048-46-8; Common name BSA. Best for mid-scale projects needing a reliable dry powder supply. Caution: ensure compatibility with your storage environment to avoid moisture uptake.
Albumin, Bovine Fraction V [BSA], 1 Kilogram
Brand: RPI. Features: For research or further manufacturing use only; not for food or drug use. CAS 9048-46-8; Common name BSA. Best for long-term inventory and high-volume labs. Caution: large quantities require adequate storage and handling to prevent moisture uptake and denaturation.
Bovine Serum Albumin Standard [2mg/ml] – 2 x 5 ml – Cepham Life Sciences
Brand: Cepham Life Sciences. Features: Purity: BSA standard with 2 mg/ml concentration; liquid form; easy to mix with reagents. Best for calibration and quantitative assays. Limitation: liquid standards require proper handling and storage conditions to maintain accuracy.
Bovine Serum Albumin Solution, 20mg/ml Solution, 5 Milliliters
Brand: RPI. Features: For research or further manufacturing use only; not for food or drug use. CAS 9048-46-8; 26628-22-8; Common Name: BSA Solution. Best for ready-to-use dilutions and quick assay setup. Limitation: not a powder; requires storage as a liquid and may have limited shelf life after opening.
Buying Guide
Key considerations when selecting BSA products for lab work:
- Format suitability: Choose a powder if you need precise mass and long-term storage; choose a liquid if you require immediate use and easy dilution.
- Intended use: Ensure the product is marked for research or manufacturing use and not for food or drug applications.
- Purity and source: Verify the CAS number and common name to confirm the material is standard BSA and appropriate for your assay.
- Storage and stability: Powder forms demand moisture-controlled storage; liquids require proper sealing and temperature control.
- Volume and scale: Align product quantity with your project size to minimize waste and ensure consistent results over time.
- Safety and compatibility: Check for any handling warnings and ensure compatibility with buffers and reagents in your workflow.
FAQ
- What is bovine serum albumin primarily used for?
– It is a widely used protein standard and stabilizer in biochemical assays, calibration, and protein quantification workflows. - Which format is best for precise weighing?
– Powdered BSA is best for precise mass measurement and custom concentration preparation. - Are BSA products suitable for all lab applications?
– Most BSA products marked for research use are not intended for food or pharmaceutical applications; check labeling and handling notes. - Can BSA standards be used for calibration?
– Yes, BSA standards (especially liquid 2 mg/mL) are commonly used for calibration in protein assays. - Do powder and liquid forms require different storage?
– Yes. Powder generally needs moisture control; liquids require container sealing and temperature considerations. - What should I consider when selecting the largest powder quantity?
– Consider long-term storage, waste minimization, and cost per gram to decide between 25 g, 100 g, or 1 kg quantities.
