Usually IgG antibodies are produced in mice. What is the advantage of producing IgY bird's antibody instead of IgG?

    $\begingroup$ Are you sure antibodies are produced in retina? Can you add a reference to support that claim? $\endgroup$ – WYSIWYG May 8 '19 at 13:40
  • $\begingroup$ I have seen, rat, mouse, rabbit, hamster and goat antibodies but not chicken. Birds do not have IgG but IgY. However, the principles should still be the same. $\endgroup$ – WYSIWYG May 8 '19 at 13:54

    $\begingroup$ That paper says that antibody against chicken galectin was raised in rabbit. Please read the paper carefully. $\endgroup$ – WYSIWYG May 8 '19 at 14:18

    $\begingroup$ @ManuelMilla Again, please read the paper carefully. It is very clear from the abstract that the antibody was used for immunohistochemical imaging. $\endgroup$ – WYSIWYG May 8 '19 at 15:15
  • $\begingroup$ Furthermore, to add to what WYSIWYG has pointed out, it is a polyclonal antibody (the IgG fraction from rabbit serum), not a monoclonal as you originally seemed to think. $\endgroup$ – user1136 May 8 '19 at 17:45
