Anti-Frizzled-1 (FZD1) (extracellular) Antibody (#AFR-041) is a highly specific antibody directed against an epitope of the rat protein. The antibody can be used in western blot analysis. It recognizes an extracellular epitope and is thus ideal for detecting the receptor in living cells. It has been designed to recognize FZD1 from rat, mouse, and human samples.
