Nitta Gelatin's collagen- and gelatin-based reagents are trusted products with proven performance that have long been used by many researchers. Their collagen products have superior optical clarity even after gel formation is completed. This provides an opportunity to accurately observe biological samples embedded in collagen gel matrices.


Cellmatrix® Series (Collagen for Cell Culture)

FUJIFILM Wako offers five different types of Cellmatrix® collagen products, ensuring that you can find the ideal reagent for your specific research needs.

●Type Ⅰ-A
・Ideal for collagen-gel cultures. 
・Perfect for microscopy due to its outstanding transparency.
●Type Ⅰ-P
・Recommended for both collagen-gel cultures and collagen-coating of culture surfaces.
・Forms softer gels than Type I-A.
・Pepsin-solubilized collagen from porcine tendons.
●Type Ⅰ-C
・Recommended for collagen-coating of culture vessels surfaces.
・Pepsin-solubilized collagen from porcine skin.
●Type Ⅲ
・Recommended for collagen-coating of culture vessels surfaces.
・Does not form gels.
・Type-III collagen from porcine skin.
●Type Ⅳ
・Recommended for collagen-coating of culture surfaces.
・Does not form gels.
・Type-IV collagen; purified from bovine anterior lens capsules using pepsin treatment.

MedGel® Ⅱ

MedGel® Ⅱ Series (Gelatin-Based Matrix Materials for Controlled Release Formulations: An Advanced Version of the MedGel® Series)

MedGel® Ⅱ is an improvement on the original MedGel® ("TaBaTa Gel for controlled release" outside of Japan), 
a bioabsorbable gelatin hydrogel for the sustained release of physiologically active substances.

  • 00529_img08.png
  • [Advantages]
    ・Ready-to-use: Just add, dropwise, a solution of bioactive agents to be released at a controlled rate.
    ・Stabilizes encapsulated bioactive therapeutics.
    ・Enables local administration of drugs.
    ・Gelatin hydrogel prepared withoutchemical crosslinking agents.
    ・Sterilized by gamma irradiation.

    ・Drug delivery research and the development of new drug delivery systems (DDSs).
    ・Basic and clinical research in cell therapy and regenerative medicine. 

    [Improvements on the Original MedGel®]
    ・Changed the method of sterilization to γ irradiation.
    ・Implemented a new crosslinking method that eliminates the need for chemical crosslinkers.

MedGel® ("TaBaTa Gel for controlled release" outside of Japan) is a bioabsorbable gelatin based hydrogel that can release physiologically active substances in a gradual and continuous manner. It was developed based on research by Prof. Yasuhiko Tabata of the Institute for Frontier Medical Sciences at Kyoto University. MedGel® is a water-insoluble polymer network formedby crosslinking gelatin. This polymeric network captures therapeutic agents primarily via electrostatic interactions. Following in vivo implantation MedGel® - therapeutic reagent complex, MedGel® is degraded by endogenous enzymes, allowing entrapped drugs to diffuse out of the network. MedGel® is also designed to be completely degraded and absorbed in the body. This eliminates the need for implant removal surgery after the drugs are exhausted.
