Answer:

Rat anti-goat linked to Cy3

Explanation:

Indirect immunofluorescence microscopy is a technique used to localize endogenous marker proteins, having this approach high sensitivity. Secondary antibodies are produced by immunization of the target species with antibodies of one 'second' species. In a standard immunofluorescence assay, the secondary antibodies are linked to fluorophores and incubated with the primary antibody. In this case, the Cy3 fluorescent probe is used for labeling secondary antibodies, it is a fluorophore that absorbs light at 550 nm and emits at 570 nm.
