A mobility shift assay for TaqS DNA polymerase (A) and NeqSSB-TaqS DNA polymerase (B) with ssDNA and dsDNA. The output products were analyzed on a 2% agarose gel with ethidium bromide in the UV light. The reaction mix contained 10 pmol Oligo (dT)76 and/or 2.5 pmol PCR product with a length of 100 bp. In panel A: 1. Oligo (dT)76 and 0 pmol TaqS DNA polymerase; 2. 100 bp PCR product and 0 pmol DNA polymerase; 3–9. Oligo (dT)76 and 100 bp PCR product with 24,6; 49,2; 98,4; 196,8; 393,6; 787,2; 1574,4 pmol of TaqS DNA polymerase, respectively. In panel B: 11. Oligo (dT)76 and 0 pmol NeqSSB-TaqS DNA polymerase. 12. 100 bp PCR product and 0 pmol NeqSSB-TaqS DNA polymerase. 13–19. Oligo (dT)76 and 100 bp PCR product with 3,3; 6,6; 13,2; 26,4; 52,8; 105,6; 211,2 pmol NeqSSB-TaqS DNA polymerase, respectively.
