Allele Analysis · CVENTBIO
Discover & Compare Alleles
Analyze retained reads from a completed PCR order. Define your target regions, discover supported variants, or search for expected allele sequences.
Experimental analysis. Detection limits and biological accuracy remain unvalidated. Results depend on read quality and coverage.
From strands to alleles




Conceptual illustrations; example sequences and percentages.
Understand mixed amplicons
Resolve mixed sequences
See distinct, supported alleles when a mixed Sanger trace is difficult to interpret.
Find sequence changes
Compare substitutions, insertions and deletions against your reference.
Analyze GC-rich targets
GC-rich amplicons can be analyzed with sufficient amplification and usable read coverage.
What your report shows
See each supported allele’s sequence, length, reference differences, supporting reads and read percentage.

Sample A · Example
| Allele | Length | Support / usable reads | Reads % |
|---|---|---|---|
| A1 | 240 bp | 700 / 1,000 | 70% |
| A2 | 237 bp | 200 / 1,000 | 20% |
| A3 | 240 bp | 80 / 1,000 | 8% |
2% of usable reads are unassigned in this example. Percentages describe usable reads.
Choose your analysis
Discover alleles
Identify supported sequence variants between your chosen flanks and compare them with a reference.
Find specified alleles
Search for up to four expected allele sequences. Results show detected, not detected or inconclusive when evidence is insufficient.
Get started
- Select your order and samples. Use completed full-length PCR sequencing results with retained reads.
- Define your target. Enter shared left and right flanks (15–200 bases each) and a reference target (1–1,000 bases).
- Run and review. Choose an analysis mode, then view your allele report and download the data.
