Description and Specification


Description Pierce Bovine Serum Albumin Standard, 2mg/mL
Formulation BSA in 0.9% sodium chloride with sodium azide
Quantity 50mL
Sufficient For Preparing many standard curves for tube or microplate protein assays

These bovine serum albumin (BSA) solutions are protein concentration reference standards for use in BCA, Bradford and other protein assay protocols. BSA is the universally accepted reference protein for total protein quantitation. The albumin standard is precisely formulated at 2mg/mL in an ultrapure 0.9% sodium chloride (saline) solution. The concentration of the stock solution is calibrated by direct comparison to purified BSA (Fraction V) from the National Institute of Standards and Technology (NIST™). The product is available in three convenient package formats: 1mL glass ampules, 50mL polypropylene bottles, and complete sets containing seven ready-to-use dilutions.


  • Universal – recognized as the industry standard for protein quantitation in colorimetric protein assays

  • Pure and stable – supplied in ultrapure 0.9% saline solution with 0.05% sodium azide; room temperature stable

  • Accurate and consistent – precisely formulated at 2.00 +/-0.03mg/mL compared to a NIST reference

  • Convenient – choose 1mL ampules, a 50mL bottle, or a complete set containing seven ready-to-use dilutions


2mg/mL BSA solution (Part No. 23209, 23210) or 7-solution set of different concentrations (Part No. 23208)

Recommended for:

Protein assay quantitation standard; Protein recovery control for desalting and other column procedures; General calibration of spectrophotometer UV-lamp (A280)
