                  Application No.   08/912,378                                                                              
                         9.     A composition for delivering a nucleic acid to a bacterial cell, the                        
                                composition comprising                                                                      
                                    the nucleic acid mixed with a macrocycle having a net positive                          
                                    charge selected from the group consisting of natural porphyrins,                        
                                    natural phthalocyanins, synthetic porphyrins, synthetic                                 
                                    phthalocyanins, and conjugates thereof, in an amount effective                          
                                    to enhance delivery of the nucleic acid to the bacterial cell,                          
                                    wherein the nucleic acid is a nucleic acid to be delivered to a                         
                                    bacterial cell, wherein the nucleic acid is ionically bound to the                      
                                    macrocycle.                                                                             
                         We also note that claims 4 and 12 further limit the macrocycle of claims                           
                  1 and 9, respectively, to porphyrin.  In addition, claim 13 further limits the                            
                  composition of claim 9 by requiring that the composition be made by mixing a                              
                  plurality of the porphyrin and a plurality of the nucleic acid in a ratio resulting in                    
                  all of the plurality of the nucleic acid binding to the plurality of the porphyrin.
