一般描述

结冷胶，吉兰糖胶，可替代琼脂用作微生物和组织培养基中的凝胶剂。结冷胶广泛用于各种固定基质。在电解液的存在下，可以低浓度形成坚实的凝胶。结冷胶是由2:1:1的D-葡萄糖、L-鼠李糖和D-葡糖醛酸经β(1→4)糖苷键连接而成的线性四糖。

  1. Which document(s) contains shelf-life or expiration date information for a given product?

    If available for a given product, the recommended re-test date or the expiration date can be found on the Certificate of Analysis.

  2. How do I get lot-specific information or a Certificate of Analysis?

    The lot specific COA document can be found by entering the lot number above under the "Documents" section.

  3. How do I find price and availability?

    There are several ways to find pricing and availability for our products. Once you log onto our website, you will find the price and availability displayed on the product detail page. You can contact any of our Customer Sales and Service offices to receive a quote.  USA customers:  1-800-325-3010 or view local office numbers.

  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.

Poly(tetrafluoroethylene) (PTFE) is a unique polymer with highly desirable properties such as resistance to chemical degradation, biocompatibility, hydrophobicity, antistiction, and low friction coefficient. However, due to its high melt viscosity, it is not possible to three-dimensional (3D)-print PTFE structures using

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
