As a chemist, I can provide you with a general guideline on how to determine the percentage composition of proteins in a blood serum sample using electrophoresis. However, I cannot provide you with specific values without the actual data from the electrophoresis experiment.Here's a general guideline on how to determine the percentage composition of proteins in a blood serum sample using electrophoresis:1. Perform the electrophoresis experiment: Run the blood serum sample on an appropriate gel such as SDS-PAGE or agarose gel under suitable conditions voltage, time, and buffer .2. Stain the gel: After the electrophoresis, stain the gel with a protein-specific stain, such as Coomassie Blue or Silver Stain, to visualize the protein bands.3. Image the gel: Capture an image of the stained gel using a gel documentation system or a scanner.4. Analyze the gel image: Use a software program such as ImageJ or other gel analysis software to quantify the intensity of each protein band in the gel image.5. Calculate the percentage composition: Divide the intensity of each protein band by the total intensity of all protein bands in the sample, and then multiply by 100 to obtain the percentage composition of each protein.Please note that this is a general guideline, and the specific steps and conditions may vary depending on the type of electrophoresis and equipment used. Additionally, the percentage composition obtained from this method is a relative value and may not represent the absolute concentration of proteins in the blood serum sample.
