FIG. 2.

HPV general standard pattern. The general standard pattern is that obtained with a mixture of six common high-risk and intermediate-risk HPV types: types 16, 31, 33, 51, 52, and 18. The PCR products for these controls are mixed together and are shown on the top elution run. The retention time is unaffected by mixing, as can be seen by the run for each individual sample below. The gradient conditions for this general standard pattern are presented in Tables 3 and 4.
