##The best diagnostic tools currently use antibodies to sense things like hormones or viruses in a patient s bloodstream.
##The antibody-based tests are exquisitely sensitive and we can t compete with that sensitivity yet##says Keith Pardee a postdoctoral fellow in Collins lab coauthor of the Cell paper and a Wyss Institute research scientist.##
##But to make a custom antibody it costs between $4000 and $30000 and it will take between four and six months.##
But it will spur the immune system to produce antibodies that would protect them from the real virus. In 2001,
normally a small transparent plate resembling a honeycomb with 96 tiny wells. Specific antibodies are placed then into each well,
Blood samples are tested after specific antibodies that bind to antigens meet the blood in the embedded well portion of the plate.
The introduced antibodies contain enzymes whose substrates react chemically and cause a distinct change in color.
followed by small amounts of fluid containing specific antibodies that bind to antigens in the samples.
These antibodies are linked to enzymes, so when a substance containing the enzyme substrate the molecule the enzyme acts upon is added,
our immune cells respond by producing antibodies that neutralise it when they bind to specific proteins on its surface.
These antibodies continue to be made long after the virus has been cleared from our body ready to mount a quicker response should it return.
If antibodies target it then the virus has infected the person in the past. var ord=window. ord Math. floor (Math. random()*10e12;
any circulating antibodies latch on to the associated proteins on the bacteriophages. Sequencing these bacteriophages then reveals the person's viral history.
while to make antibodies, so you might not find a strong antibody response in the early stages of an infection.
The test would also not be able to distinguish between antibodies made as a result of an infection and those triggered by a vaccine.
Instead the technique might be useful in outbreaks of new viruses. Understanding how our immune system responds to other viral fragments might reveal clues as to
For example, pharmaceutical companies currently create cancer antibodies in expensive hamster ovary cells that do not often misfold proteins.
