Goat anti rabbit secondary antibody

Manufactured by Cell Signaling Technology
Sourced in United States, China

Goat anti-rabbit secondary antibody is a laboratory reagent that is used to detect the presence of rabbit primary antibodies in various immunoassays, such as Western blotting, ELISA, and immunohistochemistry. It is a polyclonal antibody produced in goats and specifically binds to the Fc region of rabbit antibodies, allowing for the amplification and visualization of the target antigen.

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
