Description

Description

Pierce Dilution-Free BSA Protein Standards are high-quality bovine serum albumin reference samples for generating accurate standard curves and calibration controls in total protein assays. They are packaged as a set of seven pre-diluted standards in a multichannel pipette-friendly tubestrip, eliminating the need for serial dilutions. The tubestrip includes a single empty tube that enables users to add their own sample buffer for the purpose of blank subtraction.

Features of Dilution-Free BSA Protein Standards include:
Multichannel pipette compatible—unique tubestrip design allows simultaneous transfer of a full standard curve dilution series to a microplate
• Convenient—complete set 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
Accurate—reduce pipetting error from serial dilutions

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 set of standards is prepared from a stock solution that is calibrated by direct comparison to purified BSA (Fraction V) from the National Institute of Standards and Technology (NIST).

Applications include:
• Protein assay quantitation standard (BCA Protein Assay, Bradford Assay, etc.)
• Protein recovery control for desalting and other column procedures
• General calibration of spectrophotometer UV-lamp (absorbance at 280 nm)

Selection of a protein standard is potentially the greatest source of error in any protein assay. The best choice for a standard is a purified, known concentration of the most abundant protein contained in the samples being tested. Often, a highly purified, known concentration of the protein of interest is not available or is too expensive to use as the standard or the sample itself is a mixture of many proteins (e.g., cell lysate). In such cases, the best standard is one that will produce a normal (i.e., average) color response curve with the selected protein assay method and is readily available to any researcher. BSA is such a protein, and the Pierce Dilution-Free BSA Protein Standards are the most convenient source of ready-to-use BSA standard.

For greatest accuracy in estimating total protein concentration in unknown samples, it is essential to include a standard curve each time the assay is performed. This is particularly true for the protein assay methods that produce non-linear standard curves. Deciding on the number of standards and replicates used to define the standard curve depends upon the degree of non-linearity in the standard curve and the degree of accuracy required. In general, fewer points are needed to construct a standard curve if the color response is linear. Typically, standard curves are constructed using at least two replicates for each point on the curve.
