- please solve all three parts. else negative ratings. please answer within 40 minutes. Remember answer all three parts.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?Use correct sig figs The concentration of a purified monoclonal antibody was measured using UV280 nm. The sample was diluted (200 μL of purified antibody in 800 μL buffer) prior to analysis using a spectrophotometer. Calculate the concentration of antibody in the purified fraction if the Abs=0.95 of the diluted antibody. The molar absorptivity is known to be 191,411.6 M-1cm-1 and the molecular weight is 150 kDa. The pathlength for the cuvette is 1 cm.

- Specificity Specificity is the ability to measure accurately and specifically the analyte of interest in the presence of other components that may be expected to be present in the sample matrix. It is a measure of the degree of interference from such components, as other active ingredients, excipients, impurities, and degradation products, insuring that a peak response is due to a single component only. Experimental Dissolve amount of paracetamol (20 µg/ml) powder in three different volumetric flasks containing IN HCI, IN NaOH and 6% H₂O2 respectively, then keep your solution overnight in a fume hood.

According to the results, could the buffer being used be either negamycin, tetracycline, rifamycin, or cycloheximide? Explain why based on the FRET data.Please help me answer and explain these questions: 1. Compare the abundance of A280 chromophores (W, Y, and C) to Bradford sites (loosely R and K) in BSA. 2. We used a protocol that corrects the path length in each well and normalizes the absorbance to the value that would be obtained if the path length were 1 cm (the standard path length). Using this observation and your A280 calibration data, what is your measured e280, for BSA?
