General description

Gelatin is widely used for tissue engineering and 3D Bioprinting applications. Gelatin is derived from natural extracellular matrix (ECM) components. Due to its low cost, abundance, and retention of natural cell binding motifs, gelatin has become a highly sought material for tissue engineering applications. While gelatin from porcine skin is known for its thermoreversible gelling properties, Gelatin from cold water fish skin has low gelling and melting points. This gelatin will not gel at 10°C, hence they do not have bloom strength. This unique gelatin property makes this an attractive biomaterial which are hindered by the higher thermogelation property of porcine skin such as vat-polymerization based bioprinting and microfluidics.

Application

  • Hydrogels
  • Tissue engineering
  • Bioprinting
  • Drug delivery system

Features and Benefits

  • Naturally derived polymer
  • Low gelling and melting points
  • Thermoreversible gelling properties
  • Low endotoxin and low bioburden
Low Endotoxin, low bioburden: Endotoxins have been demonstrated negatively impact cellular growth, morphology, differentiation, inflammation and protein expression. Bioburden is defined as the number of contaminated organisms found in a given amount of material. We test each lot for endotoxins as well as total bioburden (aerobic and fungal) to minimize unwanted interactions. For more information visit: Cell Culture FAQs: Bacterial Endotoxin Contamination
