품질

May contain glycerin and sulfur compounds in more than trace amounts.

제조 메모

Removal of glycerol included as a humectant can be accomplished by washing the tubing in running water for 3-4 hours. Removal of sulfur compounds can be accomplished by treating the tubing with a 0.3% (w/v) solution of sodium sulfide at 80°C for 1 minute. Wash with hot water (60°C) for 2 minutes, followed by acidification with a 0.2% (v/v) solution of sulfuric acid, then rinse with hot water to remove the acid. This tubing will retain most proteins of molecular weight 12,000 or greater.

Regeneration capacity, via somatic embryogenesis, of four wild olive genotypes differing in their response to defoliating Verticillium dahliae (resistant genotypes StopVert, OutVert, Ac-18 and the susceptible one, Ac-15) has been evaluated. To induce somatic embryogenesis, methodologies previously used in wild
