Concept explainers

Scientific Notation

We have to deal with quantities that are extremely large or very small. For example- I may have 6,500,000,000 red blood cells, or the diameter of an iron atom is 0.000000011 inches. Numbers with many zeros can be inexpedient to work with, so scientists use scientific notation. It represents very large numbers or very small numbers in a simple form. We know that whole numbers can be extended to infinity, but we cannot write such large numbers on paper. Numbers that present in millions of places after the decimal point need to be represented simply. Thus, it is difficult to represent a few numbers in their extended form. Therefore, we use scientific notation.

Calculate the volume of BSA stock that will be required to make the standard solutions needed to create the BSA standard curve. Be sure to show your work and include the volume of 0.02 M phosphate buffer required to reach a final volume of 1 mL. From a 2,000 μg/mL BSA stock, create 1 mL of each of the following stock solutions in 0.02 M phosphate buffer using individual microcentrifuge tubes: 50 μg/mL, 250 μg/mL, 500 μg/mL, 1,000 μg/mL, 1,250 μg/mL, 1,500 μg/mL. Be sure to properly label all the microcentrifuge tubes before creating the standards.
You perform a Bradford assay to determine the concentration of isolated α-lactalbumin. You use 50 μL of a two-fold diluted solution of α-lactalbumin in the assay. You generate a standard curve with the following equation for the line: y = 0.163x + 0.082. The absorbance of your sample was 0.674 AU. What is the concentration of α-lactalbumin, in mg/mL, in your sample? Give your answer to three significant figures.
The standard curve to determine the amount of betacyanin is shown below. You extracted a red pigment from a beet disc (the mass of a disc is 2 g) using 10 ml of 20% ethanol solution. You measured absorbance of the solution above the beet disc every minute for a total time of 20 minutes. The increase in absorbance was linear during a period of time from 1 min to 10 min. The absorbance at 10 min was 0.8. Calculate the amount of betacyanin extracted from 1g of a beet tissue per minute. Explain your calculations. You can use Excel or a calculator.
Pretend the results below were obtained for water from your well. The 10 mL tubes are Full Strength, or 9.9 mL of the sample plus 0.1 mL of 10x broth (here a fluorescent Brilliant Green Broth). The 1 mL tubes are 1 mL sample plus 9 mL of normal broth (so a ten-fold dilution). The 0.1 mL are that much sample with 9.9 mL of the broth (so a hundred-fold dilution). Dark green indicates coliform presence. Use the table and the figure and give me the MPN. To do so, count the number of positive tubes at each dilution. Then match the counts to the set of values that most closely fits. Yes, you need to consider the set of values for None, 1 and 0.1 taken together. For example, 5,2,1. What is the MPN estimate for this well water sample? If safe drinking water is <5 cells/100 mL would you drink this well water?
For the serial dilution, your stock solution must have a concentration of 3.5 mg/mL. How much diluent must be added to the 5.3 mg/mL red cell to prepare the stock solution? Show pertinent solution/s. 7. If the red cell suspension is the stock solution, what is being quantified in this test? What diluent/reactant should be used to detect your answer in number 7?
You will be given 1 mL of a 2.0 mg/mL solution of bovine serum albumin (BSA) and 1 mL of a 2.0 mg/mL solution of bovine gamma globulin (BGG). From these solutions, you will need to make 100 μL of each of the following standards using 1x MBP purification buffer as the diluent for preparation of a standard curve: 1000 μg/mL, 750 μg/mL, 500 μg/mL, 250 μg/mL, 125 μg/mL, and 0 μg/mL.
