Abstract:
The All Birds Barcoding Initiative aims to assemble a DNA barcode database for all bird species, but the 648-bp 'barcoding' region of cytochrome c oxidase subunit I (COI) can be difficult to amplify in Southeast Asian perching birds (Aves: Passeriformes). Using COI sequences from complete mitochondrial genomes, we designed a primer pair that more reliably amplifies and sequences the COI barcoding region of Southeast Asian passerine birds. The 655-bp region amplified with these primers overlaps the COI region amplified with other barcoding primer pairs, enabling direct comparison of sequences with previously published DNA barcodes.

Labeling DNA Probes
Radioisotopes, fluorophores, or small molecule binding partners like biotin or digoxigenin, are the most widely used reporter tags for labeling DNA probes. These labels can be attached to the probe DNA molecule via...
