A Species-Specific DNA Probe for Goat Fiber Identification

Abstract

The development of a species-specific DNA probe for identifying goat (e.g., cashmere and mohair) fibers is described. A 54-base oligonucleotide probe hybridizes with single stranded target goat fiber DNA under conditions of low stringency. DNA isolated from as little as 100 mg of raw goat fiber can be clearly detected. Visualization of the DNA isolated from a 100% cashmere processed garment is also demonstrated.
