Which document(s) contains shelf-life or expiration date information for a given product?
If available for a given product, the recommended re-test date or the expiration date can be found on the Certificate of Analysis.
Will the buffer or solution my protein is in interfere with Product B6916, Bradford Reagent?
A compatibility chart is listed in the bulletin. If your substance is not listed, then we recommend testing this by diluting the standard protein samples in the same buffer as the unknown samples.
What is the useful concentration range that can be measured by Product B6916, Bradford Reagent?
The Bradford Reagent requires no dilution and is suitable for micro, multiwell plate, and standard (cuvet) assays. The linear concentration range is 0.1-1.4 mg/mL of protein, using BSA (bovine serum albumin) as the standard protein.
When using Product B6916, Bradford Reagent, how soon after my color development do I need to read my assay?
he protein-dye complex is stable up to 60 minutes. The absorbency of the samples must be recorded before the 60 minute time limit and within 10 minutes of each other.
When using Product B6916, Bradford Reagent, what can I do if I have a very dilute sample in a large volume?
The micro assay using this same reagent may be an option for you. The micro assay is used when a large volume (at least 1 mL) of a dilute sample is available for testing. The linear concentration range of this assay is lower than the standard or multiwell plate assays, (1-10 μg of total protein in 1 mL).
Is the BSA standard supplied with Product B6916, Bradford Reagent?
No, we do not supply the BSA standard with this reagent. We recommend using one of the following products: Protein Standard (BSA) Solution, (2 mg/mL), Product No. P0834 or Protein Standard (BSA) Solution, (1 mg/mL), Product No. P0914, if lower concentrations of protein are to be measured.

The field of proteomics is continually looking for new ways to investigate protein dynamics within complex biological samples. Recently, many researchers have begun to use RNA interference (RNAi) as a method of manipulating protein levels within their samples, but the ability to accurately determine these protein amounts remains a challenge. Fortunately, over the past decade, the field of proteomics has witnessed significant advances in the area of mass spectrometry. These advances, both in instrumentation and methodology, are providing researchers with sensitive assays for both identification and quantification of proteins within complex samples. This discussion will highlight some of these methodologies, namely the use of Multiple Reaction Monitoring (MRM) and Protein-AQUA.
