A phagehunter performs a spot titer using standard techniques (3 ul of each dilution spotted to lawn) of a lysate obtained from an optimum webbed plate experiment. The phagehunter counts 4 plaques on the 10-8 dilution spot. Which of the following scenarios is the best choice for the phagehunter to do next? a.) The phagehunter has not achieved a high enough titer lysate to move forward with characterization experiments, so they should try to make more optimum webbed plates. b.) The phagehunter has not achieved a high enough titer lysate to move forward with characterization experiments, so they should adopt a phage from direct isolation. c.) The phagehunter has achieved a high enough titer lysate to move forward with characterization experiments. d.) The phagehunter has not achieved a high enough titer lysate to move forward with characterization experiments, so they should go back to the pick-a-plaque experiment.

Is there any relationship between dedifferentiatiation and the higher degree of success achived in plant tissue culture experiments?

Enzyme Potato Experiment   Observation Interpretation Test Tube 1 H2O2 + 1 piece uncooked potato + 1 mL H2O     Test Tube 2 H2O2 + 1 piece cooked potato + 1 mL H2O     Test Tube 3 H2O2 + 1 piece uncooked potato (cut into small pieces) + 1 mL H2O     Test Tube 4 H2O2 + 1 piece uncooked potato + 1 mL vinegar

B) A total of 2.5 x 105 cells were harvested from the patient. You need the cells to fill a scaffold with dimensions of 20mm x 20mm x 4mm at a final density of 2 x 104 cells/mm³. After culturing the harvested cells, you found that they have a doubling time of 36 hours. Determine the total number of cells (N) needed to fill the scaffold. Show your work.

I need help to Produce a BSA standard curve. Use Excel to draw a scatter plot (data points are not connected with a line) using the data obtained for the BSA standards. Generate a linear regression line. the graph must indicate and clearly label on the y axis the average absorbance values obtained for diluted skim milk, diluted whey pH 4.2 and diluted whey pH 4.8 and draw a dashed horizontal line that will intersect the regression line; from the trendline intersect then draw a vertical line that will intersect with the x-axis. here are my numbers: BSA CONCERNTRATION AVERAGE 20 ug/mL BSA 0.175 50 ug/mL BSA 0.231. 100 ug/mL BSA 0.480 150 ug/mL BSA 0.680 200 ug/mL BSA 0.838 Absorbance 1 Absorbance 2 Average SKIM MILK 0.536 0.628 0.582 WHEY PH 4.8 1.09 0.963 1.027 WHEY PH 4.2 0.313 0.191 0.252
