Manually Designing Primers for SYBR

Green Dye Assays
You may choose to manually design primers and probes for a various reasons:
• Automated primer/probe design did not find primers.
• To design primers according to your own specifications.
Creating a
Quantification
Document
Create a Quantification document and load a sequence file as you would for automatic
primer/probe set design. See “Creating a Quantification Document” on page 9.
Manually
Designing the
Primers
To design the Forward Primer:
1. In the Sequence tab, select a putative forward primer sequence region containing at
least 25 bases.
2. Copy (Ctrl+C) the sequence.
IMPORTANT! The Primer Probe Test Tool eliminates non-ATCG bases. Before copying
a sequence, change any non-ATCG bases, or select a different region of the sequence.
3. Select Too ls > P rime r Probe Te st Too l. The Primer Probe Test Tool dialog box
appears (see “Figure 7. Primer Probe Test Tool dialog box” on page 24).
