Chapter 17, Problem 2VI
Summary Introduction
To answer:
Which patients are most likely uninfected using the immunoblot results for a particular antigen?
Introduction:
A western blot is also termed as immunoblot. It is a testing method used to identify a particular protein molecule, for example, an antibody (complex mixture). General practitioner use western blot in order to confirm the occurrence of HIV antibodies or proteins (blood serum) against the bacterium that cause Lyme disease in human.

The attached image has the following Newick format:
((HIV-1 retropepsin:0.67441,(HIV-2 retropepsin:0.40370, Simian immunodeficiency:0.40370):0.27071):0.963537,(Bovine immunodeficiency:1.34405,Feline immunodeficiency:1.34405):0.295328);
Examine the branch lengths. What do they tell you about the evolutionary time between the branch points?• Which branchings are more ancient and which are more recent?• What would you conclude about these immunodeficiency virus proteases, based on this small analysis?
A student completed a plate and liquid lysate followed by a plaque assay. The volume harvested for the plate lysate was 5.5mL and had a titre of 1.8x10^10 PFU/mL. The volume harvested for the liquid lysate was 9.5mL and had a titre of 1.1x10^10 PFU/mL. Which of these lysates had the highest viral yield?
Liquid lysate had the highest yield
Plate lysate had the highest yield
They both have the same yield
why do we have to do a western blot confirmatory testing after doing an ELISA screening test for HIV?
