Aims/hypothesisAdequate evaluation of protein expression is a crucial prerequisite for functional studies. Commonly used strategies comprise detection of proteins by specific antibodies using western blotting and immunohistochemical staining, or detection of mRNA by in situ hybridisation and RT-PCR. We evaluated the tools for the detection of free fatty acid receptor 1 (FFAR1) expression.MethodsCommercially available antibody preparations were used to detect endogenous expression of the FFAR1 receptor and this was compared with cell preparations deficient or overexpressing the mouse or human receptor. Concentrations of mRNA were evaluated by RT-PCR.ResultsAll insulin-secreting cells, INS-1E, Min6 and mouse islets showed specific expression ofFfar1at the mRNA level. However, none of the commercially available antibodies specifically detected rat, mouse or human FFAR1.Conclusions/interpretationProper positive and negative controls are an important prerequisite for the evaluation of FFAR1 expression.
