Anti-[beta]hCG antibody 3341 was coupled with TMR or Alexa546 using a similar technology with a 15-fold molar excess of the fluorochromes. The labeling degrees, determined photometrically according to the reagent supplier's instructions, were 2.2 (TMR/IgG) and 2.8 (Alexa/IgG).
Differential staining of these microspheres with orange-emitting and red-emitting fluorochromes produces an array of 64 individually addressable populations of microspheres (3).
Carboxylate-modified polystyrene microspheres (5.5 [micro]m diameter) were dyed with various amounts of orange-emitting and red-emitting fluorochromes (Luminex Corp.).
Heterozygous or homozygous status may be discriminated in a single reaction when different alleles are amplified by primers labeled with different fluorochromes [76,78].
All forward primers were fluorescently labeled with different fluorochromes (6-FAM, VIC, NED, and PET) (Applied Biosystems, USA).
(4,5) On the basis of a combination of 4 fluorochromes as used previously in some commercially available FISH probes, such as the Vysis Melanoma FISH probe kit (Abbott Molecular), it is feasible to design a multiplex probe that would concurrently analyze up to 3 oncogenes on a single FISH slide (eg, ALK, ROS1, and RET; see Figure, A, for a probe design and Figure, B, for a proposal of an interpretation algorithm).
