  • This antibody was evaluated in a study of commercially available antibodies against rat alpha7 Nicotinic Acetylcholine Receptors (α7 nAChR). Seven antibodies were included in the study and tested in the applications Western blotting and fluorescent immunocytochemistry.

    Both tests were performed using the rat pituitary cell line GH4C1, which has no endogenous expression of α7 nAChR. For immunofluorescence, antibody staining of native cells was compared with staining of cells transfected with rat α7 nAChR cDNA. Expression of α7 nAChR in GH4C1 was confirmed by RT-PCR. The same two cell-lines were used for Western blotting, together with GH4C1 cells transfected with C-terminally GFP tagged α7 nAChR or GFP.

    This antibody (Lot No. GR89867-1) did not recognize rat α7 nAChR in any of the two applications. In Western blotting a single background band of approximately 90 kDa was detected in all four cell lines. In immunocytochemistry signals of similar intensities were observed in transfected and control cells.
