Combien de temps et à quelle température peut-on stocker des aliquôts de solution l'élastase reconstituée dans le tampon pH5.5, s'il vous plaît?
1 回答-
This material is lyophilized from a solution containing 0.05 M sodium acetate (pH 5.5) and 0.6 M NaCl. The solution stability of this product has not been determined. However, reconstitution in water and snap-freezing in aliquots, then storing at -70°C, is recommended.
