You want to subculture your cells from T25 flask to 96-well plates. You first collected your cells in a tube with 5ml of culture medium. Then carried out a trypan blue assay and counted your cells with a hematocytometer as shown in Figure below. Answer the questions according to the results: a. Calculate the concentration of the stock including the dead and living cells. Dont forget to show the units! b. Calculate the percentage (%) of the living cells in the stock. c. You want to seed 6000 living cells into each well of 96 well plates, then calculate the volume you should take from the stock for each well. 輯 1 mm I IRE

QUESTION 2 The SARS-COV-2 pandemic resulted in the desire to design ELISA assays to either detect antibodies against SARS-CoV-2 protein (previous infection), or detect viral protein (current infection). You plan to express the mutant spike protein variant using the plasmid pictured below as your template. Here's the sequence you want to put in its place: https://www.ncbi.nlm.nih.gov/nuccore/AY429073.1?report=fasta, this is the DNA sequence you're going to buy as a gene block! But you need to add a couple things to it first so it'll get into the plasmid. To do so, you're going to need to remove the current insert (represented by the yellow arrow beginning at position 833-4867). Question: What restriction sites are you going to add at the ends of the gene? Answer can be in nucleotides or the enzyme name. For the first blank fill in the site name/sequence you'd add at the beginning of the gene (5' / C-terminus end) and for the second blank fill in the sequence/site name you'd add at the…
