You have a stock of BSA protein at the concentration of 100pg/mba You want to do a Bradford assay to make a standard curve and determine the protein concentration of
unknown samples. To make your standard curve, you should make the following
dilutions of the BSA to use as your standards. Note that final volume of standards
changes for each.
Show your work below for the amounts of BSA stock and water to mix to make
each of the following standards:
Standard #1: 1000L of 50ug/mL BSA
Volume of BSA stock:
Volume of water:
Standard #2: 100L of 25pg/mL BSA
Volume of BSA stock:
Volume of water:

In tossing one coin 10 times, what are your chances for tossing a head? a tail? 2. in tossing one coin 100 times, what are your chances for tossing a head? a tail? 3. in tossing one coin 200 times, what are your chances for tossing a head? a tail? deviation = ((absolute value of the difference between expected heads and observed heads) + (absolute value of the difference between expected tails and observed tails)) divided by total number of tosses. this value should always be positive. 4. what is the deviation for 10 tosses? 5. what is the deviation for the 100 tosses? 6. what is the deviation for 200 tosses? 7. how does increasing the total number of coin tosses from 10 to 100 affect the deviation? 8. how does increasing the total number of tosses from 100 to 200 affect the deviation? 9. what two important probability principles were established in this exercise? 10. the percent of occurrence is the obtained results divided by the total tosses and multiplied by 100%. toss the coins 100 times and record your results. calculate the percent occurrence for each combination. percent head-head occurrence: percent tail-tail occurrence: percent head-tail occurrence:
