A touch panel includes a substrate and sensing units. More particularly, this invention relates to a method of treating cancer by administering an erbB2 ligand in combination with an erbB antibody. Advantageously, in some embodiments, the methods, compositions, and kits does not require the formation or purification of a DNA-protein adduct prior to the addition of the polynucleotide to be cloned. The executing unit receives the second direct voltage and thus executes a system function of the electric apparatus.
