GelXA, Medium Ma, 0.25 LAP


GelXA supports ionic and light-induced crosslinking. Dual crosslinking capabilities enable users to tune the construct’s stiffness to the environment of a specific cell type (Figure 20). This enables researchers to analyze tissue-specific models to observe cell-matrix interactions and responses such as cell proliferation, differentiation and migration. Warming GelXA to 37 degrees Celsius liquefies the bioink and allows for gentle cell mixing. CELLINK’s GelXA incorporates a GelMA base, xanthan gum and alginate to enhance printability, ease-of-use and stability. You can print it at room temperature and use photoinitiator-assisted crosslinking, ionic crosslinking or a combination of both. Interested in developing your own formulation, check out our GelMA and Alginate Kit, and our Xanthan gum powder to mix your own formulation. GelXA is the base for many advanced formulations including: GelXA Fibrin GelXA Skin GelXA Bone GelXA Cartilage GelXA LAMININK Description Available in 3 mL cartridges. Includes crosslinking agent. Sterile production and packaging. Three-month shelf life. For research use only. Not for human use. Product number: IK3X21020301 (1 x 3 mL) Product number: IK3X21020303 (3 x 3 mL) We began offering a new and improved GelXA formulation in September 2019. The new blend enables more efficient photocrosslinking and a slightly lower stiffness after ionic crosslinking. If you would like to order the previous version, our team can prepare it upon request. Specifications The bioink has the following quality criteria: Appearance Semi-translucent gel Sterility Sterile Endotoxin level <30 EU/mL Cell viability ≥75% viable mesenchymal stem cells for 7 days pH 6.5-7.4 GelMA degree of methacrylation 45-55% Viscosity 1-1 000 Pa·s
