Cleaver Scientific supplies all these reagents, include runSAFE, a non-toxic DNA stain that works with blue light for increased cloning efficiency and safety of use. If bottle is still not opening, repeat steps with warmer water. Therefore the viscosity values obtained for a solution of agar could depend on its previous history.
Dehydration must be sufficient to guarantee the seaweed's preservation, otherwise an anaerobic fermentation will occur inside the bales causing high temperatures and even carbonization of the seaweeds during storage in warehouses. The simple water solution has that gelling power.
