Question CompleteMarked out of 1.00
You are required to makeup a calibration standard via a serial dilution using a stock protein solution with a
concentration of 0.6 mg/mL and phosphate bu ered saline (PBS) as the diluent. The serial dilution factor is 1/2 (one
half, or 50%) and you require at least 50 μL of each standard to prepare your calibration curve.
How much stock protein solution and PBS should you use to prepare your first dilution standard (the one
with the highest concentration) in the series?
What will the concentration of the first dilution standard be in μg/mL?
Select the correct two responses from the options below:
a. 80 μL Stock protein solution + 40 μL PBS
b. 30 μL Stock protein solution + 30 μL PBS
c. 150 μg/mL
d. 200 μg/mL
e. 300 μg/mL
f. 60 μL Stock protein solution + 60 μL PBS

Which cells are responsible for activating the haemostatic mechanism?
Select one:
a. Thrombocytes
b. Leukocytes
c. T cells
d. B cells
e. Monocytes
6
A protein with a low a inity to a specific material surface:
Select one:
a. Will initially adsorb to the surface in a proportion reflecting its concentration in solution and then be displaced by proteins
with a higher a inity to the surface
b. Will not adsorb to the surface even if it is in a relatively high concentration in solution
c. Will initially adsorb to the surface in a proportion reflecting its concentration in solution and then displace proteins with a
higher a inity to the surface
d. Will rapidly adsorb to the surface and quickly occupy all available binding sites
