General description

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.

Application

Gelrite, goma gellan, se recomienda como un agente gelificante para utilizar en lugar del agar en medios microbiológicos. La goma Gellan se utiliza en una gran variedad de matrices de inmovilización.

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

    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.

  5. What is Product G1910, Gelzan CM?

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

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

    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.

  7. What is the Department of Transportation shipping information for this product?

    Transportation information can be found in Section 14 of the product's (M)SDS.To access the shipping information for this material, use the link on the product detail page for the product. 

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

    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%.

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

    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.

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

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

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

    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.
