                                  Your guide to selecting nuclear, membrane, ER, or other organelle markers. 

                                  Antibodies against specific organelles, the cell membrane, or cytoskeletal components allow you to explore protein localization in situ. Also, you can use them in western blot analyses to confirm the proper fractionation of cell lysates.

                                  Whether you want nuclear, membrane, ER, or other organelle markers, we have the antibodies you need.
