1. *Please copy & paste the target gDNA sequences in FASTA format :

or upload a data file:

2. Input data description: (optional) (Please use the short words)

3.Primer3 parameters:

 1）PCR Primer parameters:

• Primer Size  Min: Opt: Max:
• Primer Tm  Min: Opt: Max:
• Primer GC % Min: Opt: Max:
• Max Tm Difference:
• Max Poly-X: bp
• Max Self Complementary:
• GC Clamp:
• PCR Amplicon Size Range: bp (By this default setting, amplicon size will be tried for 501-1000 firstly, then, 301-500, 1001-2000... till a good design is found. If the target region size is larger than the maximum amplicon size, the region will be divided into several amplicons.)
• Mispriming Library human rodent_and_simple rodent none

 2)  Sequencing Primer parameters:

• Sequencing Primer Size:  Min: Opt: Max:
• Sequencing Primer Tm:  Min: Opt: Max:
• Sequencing Primer GC %: Min: Opt: Max:
• Sequencing Primer Max Poly-X: bp
• Sequencing Primer Max Self Complementary:

4. Other parameters:

• Low Quality Sequencing Data at The First: bp
• PCR Primer Picking Region Size: bp
• Quality Sequencing Size: bp (If an amplicon was larger than this, internal sequencing primers will be designed to cover the amplicon)

5. Universal tags tailed to primer's 5'end: (optional)
    (With universal tags, the default PCR product size will be forced to 300-500 bp. No sequencing primers will be designed.)

     No forward universal tag
     M13 universal forward primer: 5'-GTAAAACGACGGCCAG-3'
     Your custom forward universal primer:

     No reverse universal tag
     M13 universal reverse primer: 5'-CAGGAAACAGCTATGAC-3'
     Your custom reverse universal  primer:

6. Choice of outputs:

• Original Primer3 output file
• Summarized primer list table
• Detailed data of PCR products

7. Your operating system: Windows Linux or Unix or Mac
