A flat (not spherical) tissue engineered skin (thickness 2.5 mm) is attached to the bottom of a dish and cultured with cell media atop it (which has an oxygen concentration of 0.15 mol/m3). The diffusivity of oxygen in the skin is 3.4 E-9 m2/s, and according to experiments that you’ve performed, you want to make sure that the concentration of oxygen in the device doesn’t fall below 0.06 mol/m3. (Below that concentration harms the cells.) The rate of oxygen consumption is -5.9 E-17 mol/[cell◦s]. What is the maximum cellularity (in cells/mL, three significant digits) that this tissue engineered skin can support?
In a randomized controlled trial, the purpose of "double blinding" or "double masking" is to _______________________________________________________________________ a. ensure that the participants are not aware as to whether they are in the treatment group or in the control group b. ensure that the investigators are not aware of which participants are in the treatment group and who are in the control group c. to ensure that the independent statisticians are also unaware of which participants are in the treatment group and who are in the control group d. both a and b e. both b and c f. both a and c g. all of the above

Does this calculation look correct? My goal isto have a target mass of 10 µg of my protein with a total volume of 30 µl. Protein was measured and found to have a concentration of at 308.35 µg/ml Recall, mass = concentration * volume 10 µg = 308.35 µg/ml * V V = 0.01 mg/ 0.30835 mg/mL = 0.032430679 mL = 32.43067942 µL Note: cannot measure this amount; two dilutions required. Dilute by 1/40: measure 2.5 µl of protein at 0.30835 µg/µl and add it to 97.5 diluent to prepare a solution of protein at 7.71 mg/ml. This diluted sample will be used further. Mass = concentration * volume 10 µg = 7.71 mg/ml * V V = 0.01 mg/ 7.71 mg/ml = 1.3 µL Therefore, will measure 1.3 µl of protein at 7.71 mg/ml and add it to 28.7 µl of diluent.
Please answer the question below and show all your work. You are given a pure protein sample to characterize and provided the following information: Its molar extinction coefficient, ε280, is 0.25 liters micromole^-1 cm^-1 Using a 0.5 cm pathlength cell, you measure the absorbance at 280 nm of a 20- fold dilution of your pure protein in solution (by this, we mean that 50 ul of the protein sample was diluted to a final volume of 1 ml) and find A280 = 0.40. What is the original concentration of the protein before dilution?
