Polyclonal chicken antibodies (IgY) for research.
Why Chicken affinity purified IgY?
- Because, higher titres against highly-conserved mammalian gene products!
Easier double immunostaining
Chicken IgYs can be used together with mouse and rabbit antibodies, without the danger of cross-reactivity. Secondary antibodies against chicken IgYs don’t cross-react with mammalian IgGs.
Higher detection signals
Chicken IgYs contain a larger glycosylation index, allowing more labeling with HRP and other antibody tags. This produces higher detection signals.
No "Fc domain" within the stem portion of a chicken IgY
This provides several advantages over rabbit IgGs:
It reduces the likelihood of having false positives in diagnostic applications, since it is the mammalian Fc domain that binds "rheumatoid factors" or other naturally occurring anti-Fc antibodies.
Does not activate mammalian complement systems, allowing the use of chicken IgYs in in vivo applications.
Does not bind to mammalian Fc receptors, avoiding non-specific binding to cells expressing such receptors (e.g., macrophages and dendritic cells).
