1. 1 5 Transfection Protocols In order to use the Cignal Finder 10 or 45 Pathway Arrays in the plate format a reverse transfection method must be employed This approach involves seeding the cell line of interest onto the transfection complexes in a one day procedure This is in contrast to traditional transfection methods in which cells are seeded on the first day of the experiment and transfection complexes are added to the cells the following day The SureFECT transfection reagent has been specifically developed as a reverse transfection reagent Optimized reverse transfection protocols using the SureFECT transfection reagent are described throughout the Cignal Finder Reporter Arrays User Manual Utilizing reverse transfection procedures results in both a time savings as well as improved reproducibility when compared to traditional forward transfection methods Conditions for using transfection reagents from other vendors in reverse transfection protocols may also be developed This will require initial process optimization studies Below is a general protocol overview for reverse transfection of the Cignal Finder 10 or 45 Pathway Reporter Arrays everse Transfection Protocol Overview 1 DAY PROCEDURE Reverse Transfection 96 well Cell Culture Plate LEE Add SureFECT Transfection Reagent and Test Nucleic Acids 900 Seed Cells for Reverse Transfection D Add 50 uL of Opti MEM to each well of Cignal Finder array plate to resuspe2. y C Firefly Luc D 1 enhancer promoter CMV immediate early enhancer promoter Firefly Luc Figure 2 Schematic representation of constructs involved in the Cignal Reporter Assay A The inducible transcription factor responsive construct expressing firefly luciferase B The constitutively expressing Renilla luciferase construct C The non inducible firefly luciferase reporter construct D The constitutively expressing GFP construct and E The constitutively expressing firefly luciferase construct IMPORTANT NOTE There are a few reports in the literature of the CMV regulatory element being activated by certain stimuli see below SABlosciences recommends that you confirm that the stimulus used in each Cignal reporter assay does not induce the CMV regulatory element in order to confirm that the CMV Renilla construct is the appropriate normalization construct for the experiment This can be done empirically by testing the impact of a stimulus on the Cignal positive control reporters which are each under the control of the CMV enhancer promoter cassette If stimulus is one of the very few reported activators of the CMV regulatory element SABiosciences advises contacting technical support e W Bruening B Giasson W Mushynski and H D Durham 1998 Nucleic Acids Research 26 2 486 489 Activation of stress activated MAP protein kinases up regulates expression of transgenes driven by the cytomegalovirus immediate
