2Barcoding Animals
Gaining Barcode Closure for Animals
10 million species x 10 barcodes each 100
million barcodes
3Barcoding Animals
Barcodes in Perspective
100 million barcodes 65 billion base pairs
4Barcoding Animals
The Time Frame
200 x 50K sequences per year
10 years to completion
5Barcoding Animals
Logistical Challenges
How do we increase production rates, lower costs
and speed analysis?
How do we recover barcodes from archival
specimens?
6The Barcoding Process
The Analytical Chain
Specimen or Tissue Sample
DNA Barcode
PCR COI
Sequence COI
Extract DNA
7The Barcoding Process
Model 1 Core Facility
Core Facility 50-100K Barcodes/Year 1M
Core Facility receives specimen samples
8The Barcoding Process
Model 2 Satellite Labs
Sequencing Facility 800K
Sequencing Facility receives PCR product

13Destructive tissue sampling is the rule
DNA Extraction
Sample Material
But the amount is small
14Non-destructive methods are available
DNA Extraction
Non-Destructive Methods
Minute specimens
Type specimens
15DNA Extraction
Two Favored Methods
16DNA Amplification
DNA Amplification
- Primer Design Optimized
Reaction
17DNA Amplification
Primer Design
18DNA Amplification
Optimized Reaction
Removes the need for PCR cleanup Lower cost by
decreasing reaction volume
