Features of continuous cell culture include the following, except ________ .
Step by step
Solved in 2 steps
- a. What is the important of subculture in animal cell culture? And explain how do yo do subculture? b. Why we use these things in animal cell culture? Serum PBS DMEM Different well plates Different volume flasksYour colleague has given you an unauthenticated cell culture grown from a primary explant. Suggest for screening the fresh cell culture you've received, with a focus on mycoplasma contamination screening, are welcome. Include in the proposal all feasible cell culture conditions.The main benefit of a three-dimensional culture system is that: O the morphology and behavior of cells are closer to what they would be within the body. O it is easier to change the media in these systems. O more cells can be grown in three dimensions. O it does not have to be sterile. O they easily give rise to specific cell lines.
- When viable cell concentrations are too high to count on an agar plate, it is common to use larger sized plates to increase the surface area for counting the colonies.True or falseExplain the expressions of primary culture, cell haH, and continuous cell haH. Explain the reason why some cells grow in suspension in culture and some grow by adhering. Give examples of these two cell types.Refer to the following diagram: 100 ul 100 uL 100 pl 100 µL 100 pl 100 pL 100 pl Volume to transfer A B C D E F G 900 uL in each tube 10 102 10 10 10 10 10 Dilutions E.CoN culture Volume of the diluted sample plated 100 ul 100 μL 100 pL 100 ul Volume of the 10 ml 10 ml original sample plated 10 ml 10 ml Plate D Plate E Plate F Plate G Given that Plate D has too many colonies to count, and Plate G has no colonies at all as a result of serial dilution, draw out all four plates and demonstrate what they might look like (assuming serial dilution has been performed correctly). Based on your drawings, identify the number of CFU/ml for Plate E and Plate F. Show your calculations.
- The following is result from a standard plate count. What is the cell density of the undiluted culture? Please follow all SPC rules. (TNTC: too numerous to count)Using the attached image, explain the observed results on the NA and ECM plates. Be sure to address why each sample is either able or unable to grow on each plate and include the genotype(s) of the cells which are capable of growth.A. Bacterial Growth Curve Categorization. Drag and drop the microbial culture plates on the column that best represents the bacterial colony growth phase. -Number of Bacterial Cells (Log) ➡➡➡ Lag Exponential Phase Phase Stationary Phase Time (h) 24 Death Phase 48
- Use the attached image to help explain the results on the NA and ECM plates. Be sure to address why each sample is either able or unable to grow on each plate and include the genotype(s) of the cells which are capable of growth.Taking microbial cells out of a stationary phase culture and putting them into a fresh, sterile medium (in which they can grow) will result in the cells entering which stage of the growth cycle? Death phase O Log phase Lag phase Stationary phaseA culture initially has P0 number of bacteria. At t = 1 hour the number of bacteria is measured to be 3/2P0. If the rate of growth is proportional to the number of bacteria P(t) present at time t,determine the time necessary for the number of bacteria to triple.
