DNA ISOLATION FROM BIOLOGICAL MATERIAL OF MARALS

The main task of maral breeding isproduction increase of antlers. Application of molecular genetic methods in maral breeding contributes to increase in reliability and accuracy of assessment of productivity and breeding value of stag deer at an early age. The purpose of the research is to test methods DNA isolation from biological material of marals. The biomaterial was selected fromstag deer of Altai-Sayan breed (blood, antler crumbs, cartilaginous tissue of the auricles). The work on DNA isolation from maral tissue samples was carried out in the bioengineering laboratory at Altai State University (Barnaul). DNA isolation was conducted using the method based on application of Chelex-100TM Resin chelating agent (Bio-Rad, USA), the method based on DNA precipitation Diamond DNA (OOO ABT, Russia) and commercial kit based on magnetic particles AMPure XP (Beckman Coulter, USA). The purification degree of the isolated DNA was assessed by PCR efficiency in reactions of amplification of the genes of cytochrome oxidase 1, cytochrome B of mitochondrial DNA. The highest concentration of maral DNA was established in isolation based on DNA precipitation (Diamond DNA). The concentration of DNA in the solution was 13.20 ng/µl (blood), 11.30 ng/µl (cartilaginous tissue), 5.74 ng/µl (antler crumbs).
