Descripción general
Gelrite, goma gellan, se recomienda como un agente gelificante para utilizar en lugar del agar en análisis microbiológicos y medios de cultivo de tejidos. La goma Gellan se utiliza en una gran variedad de matrices de inmovilización. Forma un gel duro a bajas concentraciones en presencia de un electrólito. Gellan es un tetrasacárido lineal compuesto por D-glucosa, L-ramnosa y ácido D-glucurónico en una proporción 2:1:1, unidos por enlaces β (1 → 4) glucosídico.

Mineralized hydrogels are increasingly gaining attention as biomaterials for bone regeneration. The most common mineralization strategy has been addition of preformed inorganic particles during hydrogel formation. This maintains injectability. One common form of bone cement is formed by mixing particles

Buonasera, sarebbe possibile sapere il grado di purezza del Gelzan? visto che nel Gelzan ci sarebbero sali o altri componenti, quanto è la concentrazione del Gellan Gum nel Gelzan? Rimango in attesa di un vostro riscontro.
1 answer-
The purity of this gelling agent is not determined. This material is a complex polysaccharide comprised of glucose, rhamnose, and glucuronic acid in the approximate molar ratio of 2:1:1. In addition to the base components, historical ICP analysis shows trace amounts of Calcium, Magnesium, Potassium, Phosphate, and Sodium. The maximum moisture content for this product is 16%.

How do I use Product G1910, Gelzan™ CM?
1 answer-
The G1910 is added to well-stirred water, and the dispersion heated to 85-90°C to ensure full hydration. To form a gel, the necessary amount of electrolyte, such as potassium citrate or calcium chloride, is added to the solution at 85°C and the mixture is poured or pumped into containers and allowed to cool undisturbed. The product is biodegradable, so a biocide is recommended. The typical use level is 0.2 to 2.0%.
