Question
Protein ABC is a heme-containing protein responsible in electron transfer in microalgae. The target protein was extracted using ammonium sulfate fractional precipitation and quantified using Bradford assay. A set of solutions with increasing concentration was prepared using 15.00 mg/mL analogous protein standard [refer to succeeding table]. Each solution was treated with 80 μL of Bradford reagent and diluted to 1.500mL. The absorbance at 595 nm of each solution was obtained and presented below.
Volume of protein std, μL | A595 |
0 | 0.0002 |
10 | 0.0007 |
25 | 0.0075 |
50 | 0.0165 |
100 | 0.0356 |
