| Description: | Antagonism against the adrenoreceptor α1A was tested using a recombinant human α1A receptor CHO cell line which additionally also recombinantly expresses mtAeq (mitochondrial aequorin). Antagonism against the adrenoreceptor α2A was tested using a recombinant human α2A-Gα16 receptor fusion protein CHO cell line (PerkinElmer Life Sciences) which additionally also recombinantly expresses mtAeq. Antagonism against the adrenoreceptor α2B was tested using a recombinant human α2B receptor CHO cell line (PerkinElmer Life Sciences) which additionally also recombinantly expresses mtAeq. Antagonism against the adrenoreceptor α2C was tested using a recombinant human α2C receptor CHO cell line which additionally also recombinantly expresses a chimaric G protein (Gαqi3) and mtOb (mitochondrial obelin).The cells were cultivated at 37° C. and 5% CO2 in Dulbecco's modified Eagle's Medium/NUT mix F12 with L-glutamine which additionally contains 10% (v/v) inactivated foetal calf serum, 1 mM sodium pyruvate, 0.9 mM sodium bicarbonate, 50 U/ml penicillin, 50 μg/ml streptomycin, 2.5 μg/ml amphotericin B and 1 mg/ml Geneticin. The cells were passaged with enzyme-free Hank's-based cell dissociation buffer. All cell culture reagents used were from Invitrogen (Carlsbad, USA). |
