Analysis of p300 expression. (A) An array incubated with p300 primary antibody and stained by CSA. (B) Sixty four dilution curves in eight fields on the array. y axes, p-scan intensity of p300 signal; x axes, log2(dilution factor). Numbers after cell line names are DI25 values. The order of cell line listing corresponds to placement on the array. (C) DI25 algorithm calculations for field 7. Broken line, the 25% level (at 43 units).
