Description générale

Gelrite, gellan gum, is recommended as a gelling agent for use in place of agar in microbiological assay and tissue culture media. Gellan gum is used in a wide variety of immobilization matrices. It forms a hard gel at low concentrations in the presence of an electrolyte. Gellan is a linear tetrasaccharide composed of D-glucose, L-rhamnose, and D-glucuronic acid in the ratio of 2:1:1, linked by β (1 → 4) glycosidic bond.

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

Questions

1–10 of 11 Questions  

  1. Does Gellan Gum/Gelrite have Iron, Manganese and Zinc in trace amount? It would be great to have the specific concentration detected. Thank you.

    1 answer

    1. Unfortunately, the levels of Iron, Manganese and Zinc are not analyzed for this product.

      Helpful?

  2. How many grams per liter of Product G1910, Gelzan™ CM are recommended for plant tissue culture?

    1 answer

    1. Gelzan™ CM is typically used at a concentration of 2-4 grams per liter.

      Helpful?

  3. 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

    1. 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%.

  4. What is the difference between Product G1910, Gelzan CM and Gelrite?

    1 answer

    1. The products are chemically the same. However, Gelzan CM is produced through a new and more efficient process. There are some slight differences in the specifications of the two products.

      Helpful?

  5. What is the gel strength of Product G1910, Gelzan™ CM?

    1 answer

    1. The gel strength as determined by the vendor is between 400-700 g/cm2.

      Helpful?

  6. How do I use Product G1910, Gelzan™ CM?

    1 answer

    1. 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%.

      Helpful?

  7. Is Product G1910, Gelzan™ CM, different that Gelrite?

    1 answer

    1. The G1910 is chemically the same as Gelrite, which is no longer produced. Both items are trademarked to CP Kelco U.S., Inc. They are both Gellan Gum, but the manufacturer has different specifications for these items.

      Helpful?

  8. Does Product G1910, Gelzan CM, have an expiration date?

    1 answer

    1. The lots of this product are not assigned expiration dates. The guarantee of quality is one year from the time of delivery for unopened bottles stored at room temperature.

      Helpful?

  9. What is the particle size of Product G1910, Gelzan™ CM?

    1 answer

    1. The vendor supplied particle size is 42 mesh, or about 355 μm, with a specification of not less than 95% through. This means that at least 95% of the particles should be smaller than 355 microns in diameter.

      Helpful?

  10. What is Product G1910, Gelzan CM?

    1 answer

    1. It is a low-acyl gellan gum used as a gelling agent in both microbiological assay media and tissue culture.
