BRAF V600E F3

Sequence used in wetlab experiments: GGAAAATGAGATCTACTG is taken from [1]

Usage and Biology

This is the sequence for the outer forward primer. The outer forward primer complementary to the F3c region of the template sequence [2]. Outer primer F3 hybridizes to the F3c region of the target DNA and extends, displacing the FIP linked complementary strand[2]. This displaced strand forms a loop at the 5' end primer is shorter in length and lower in concentration than FIP (forward inner primer) [2]. This F3 primer is part of the primer set that detects the BRAF V600E: TTACTTACACGCCAAGTCAATCATCCACAGAGACCTCAAGAGTAATAATATATTTCTTCATGAAGACCTCACAGTAAAAATAGGTGATTTTGGTCTAGCTACAGAGAAATCTCGATGGA GTGGGTCCCATCAGTTTGAACAGTTGTCTGGATCCATTTTGTGGATGGCACCAGAAGTCATCAGAATGCAAGATAAAAATCCATACAGCTTTCAGTCAGATGTATATGCATTTGGAATT GTTCTGTATGAATTGATGACTGGACAGTTACCTTATTCAAACATCAACAACAGGGACCAG

Alternative Sequence

As this set of primer failed to produce a positive result, we used NEB LAMP Primer Design Tool (https://lamp.neb.com/#!/) to generate an alternative set of primers. Unfortunately, due to time and budgetary constraints, these primers have not been ordered and experimented with yet.
