NTUni_p5 and NTUni_p7 (these are the Nextera transposes sequences, so their matching sequencing primers will be in the Illumina sequencing kits):

Now add the metagenoimcs primers (Hyb_F01_i5 with "ATCACG" and Hyb_R21_i7 with "CGAAAC" (rev comp) in this example) which get incorporated AFTER CYCLE 1:


Cycle 1 - only Hyb_R21_i7 hybridizes and extends to form the reverse compliment of the top strand:

Cycle 2 - the newly-formed top strand now has the compliment to the forward primer which can now prime:
AATGATACGGCGACCACCGAGATCTACAC ATCACG TCGTCGGCAGCGTC <- forward primer can now bind
                                     TCGTCGGCAGCGTCAGATGTGTATAAGAGACAG <insert> CTGTCTCTTATACACATCTCCGAGCCCACGAGAC
