Rapid Isolation Of Dna From The Mucus Of Asian Arowana (Scleropages Formosus, Osteoglossidae), Nantarika Chansue

The Thai Journal of Veterinary Medicine

Owing to arowana being listed in CITES, DNA diagnostics should not rely on conventional methods of obtaining tissue samples. A non-invasive method of obtaining material containing DNA has been developed. Mucus samples for DNA isolation can be obtained by cotton swabbing the arowana body surface with subsequent purification of DNA fragments by using phenol/chloroform. DNA sample quality is assessed by UV absorbancy at wave lengths of 260 nm and 280 nm, as well as by calculating the absorbancy ratio involving 260 nm/280 nm results in order to determine DNA sample quality and quantity. Electrophoresis is employed to assess DNA quantity …

A Missense Mutation In Pmel17 Is Associated With The Silver Coat Color In The Horse, Emma Brunberg, Leif Andersson, Gus Cothran, Kaj Sandberg, Sofia Mikko, Gabriella Lindgren

Veterinary Science Faculty Publications

BACKGROUND: The Silver coat color, also called Silver dapple, in the horse is characterized by dilution of the black pigment in the hair. This phenotype shows an autosomal dominant inheritance. The effect of the mutation is most visible in the long hairs of the mane and tail, which are diluted to a mixture of white and gray hairs. Herein we describe the identification of the responsible gene and a missense mutation associated with the Silver phenotype.

RESULTS: Segregation data on the Silver locus (Z) were obtained within one half-sib family that consisted of a heterozygous Silver colored stallion with 34 …
