LAMP Primer Design Tool

Loop-mediated Isothermal Amplification primer sets design.

Loop-mediated Isothermal Amplification (LAMP) uses 4-6 primers recognizing 6-8 distinct regions of target DNA for highly specific amplification. LAMP reactions occur under isothermal conditions without special thermal cyclers.

Key features: Four core primers + two loop primers for accelerated reaction. DNA products are >20 kb formed from numerous repeats of the 200-350 bp target sequence.

Primer Design Options

  • Distance: F2-B2: 120-160 bp; F2-F3 and B2-B3: 0-20 bp; Loop regions: 0-40 bp
  • Tm values: F1c/B1c/LF/LB: 64-66°C; F2/B2/F3/B3: 59-61°C
  • Region marking: Use [ and ] for target; /.../ to exclude
  • IUB/IUPAC codes: B=CGT, D=AGT, K=GT, M=AC, N=ACGT, R=AG, S=GC, W=AT, Y=CT

Quick Help for LAMP Primer Sets
  • Paste/upload FASTA or retrieve by NCBI accession, then tune length/Tm ranges for your chemistry.
  • Use [ ... ] to constrain the target region and /.../ to exclude problematic segments.
