On this page draw the final (finished) eliza/elisa well in a positive test run to see if a person has
antibodies against hepatitis b virus. assume the person has igg vs. the surface antigen, which is the
outer part of the virus. label all a) antigen(s)
b) antibodies (drawn as y's) label what the antibodies are against (example igg anti hiv or mouse
anti igm)
c) how you detect the presence of test, what is the end result?
keep in mind what eliza/elisa stands for. don't know look it up, talk to people. use any resource you
care too that isn't me. (more than one way to do this, pick one)

You have been asked to lead a demonstration for the undergraduate microbiology lab course about the uses of negative staining when studying bacteria. a "negative" stain does not stain the bacterial cell itself but stains the space between cells. under magnification, the acidic (negativelycharged) nature of the stain will be repelled by the negatively charged bacterial cell wall and willleave the cell colorless in a stained background. negative stains are used primarily to reveal the presence of negatively charged bacterial capsules; therefore, they are also called capsule stains. encapsulated cells appear to have a halo surrounding them. the negative stain procedure does not require heat fixation, which limits any chances of alteration in bacterial cell shape and size. the bacterial suspension is added to a drop of stain, such as nigrosin or eosin, and drawn across the glass slide using a coverslip. nigrosin staining-not safranin staining-of klebsiella pneumoniae will allow for the visualization of the cell shape and the determination of the presence of a capsule. true/false
