Figure 3. G-rich sequences caused PCR inhibitory effect.

Figure 3

(A) Deletion of CGCAGATC sequence from Stat3R and GfapR remains their inhibitory effect. (B,C) The sequentially terminal truncated forms of Stat3R and GfapR were used to test their inhibitory effect. (D) The shortest inhibitory sequences from B,C. (E) GGGGGH is sufficient to inhibit PCR using proofreading DNA polymerase.
