[Histonet] Price gouging on cocktails??

[peptolab]

Glen- If your cocktail is positive, can you say which of the three melanoma
markers (I presume HMB 45, Mart-1, and tyrosinase) are responsible for the
positivity?  If no, then maybe only one charge is appropriate as this is a
screening test and you are only screening one slide. Does the antibody
cocktail cost three times the cost of any single component marker? Are you
running controls for all three markers separately or just a control for the
cocktail. Maybe one component isn't staining well- hw would you know? I vote
for one charge.
