GenBio provides both ImmunoWELL products for more than 8-9 samples at one time
and ImmunoDOT if less than 9 specimens are tested at one time. ImmunoDOT offers
the added advantage that its performance is similar to the combined microtiter
assay and western blot result so that unnecessary supplemental western blot
testing may be avoided.
