Components
Example protocol
AT A GLANCE
Prepare 1X Bradford working solution (90 μL)
Add BSA standards or test samples (10 μL)
- Incubate at room temperature for 5 - 15 minutes
Measure the absorbance at 595 nm and 460 nm, calculate the ratio of A595/A460 nm
Thaw all the kit components at room temperature before use.
PREPARATION OF STANDARD SOLUTIONS

PREPARATION OF WORKING SOLUTION
Prepare 1X Bradford working solution by diluting 1 part Bradford Assay Solution (Component A) to 4 parts of ddH2O.

Table 2. Reagent composition for each well
Well | Volume | Reagent |
BS1-BS7 | 10 µL | Serial Dilutions (0.5 to 0.0078 mg/mL) |
BL | 10 µL | PBS |
TS | 10 µL | Test Samples |
Prepare BSA standards (BS), blank controls (BL), and test samples (TS) according to the layout provided in Tables 1 and 2.
Add 90 µL of 1X Bradford working solution to each well of BSA standard, blank control, and test samples to make the total assay volume of 100 µL/well.
- Incubate the reaction at room temperature for 5 to 15 minutes.
Measure the absorbance with an absorbance microplate reader at OD 595 nm and 460 nm, and calculate the ratio of A595/A460 nm.
Note: Please read 595 nm only if no 460 nm is available for the instrument.
