Product Description

Advanced BioMatrix offers PhotoGel®-INK, a sterile, pre-formulated 10% methacrylated gelatin ink with 0.25% LAP for rapid 3D bioprinting with the BIONOVA X. 

The PhotoGel® consists of purified methacrylated porcine gelatin (25 mL) and LAP photoinitiator. The gelatin is type A 300 bloom.  

PhotoGel® is produced from methacrylated gelatin where the gelatin has been modified by reacting the free amines, primarily the ε-amines groups of the lysine residues as well as the a-amines groups on the N-termini. ~95% of the total lysine residues of the gelatin molecule have been methacrylated.

Product Q & A

You can digest photocrosslinked methacrylated gelatin with Proteinase K or high temperatures, though these steps would likely kill cells in the process. The alternative is collagenase and trpysin, though higher concentrations may be required than standard protocols due to the photocrosslinked nature of the hydrogel. 

The PhotoGel is a type A, 300 bloom gelatin from porcine and has a molecular weight distribution that averages between 50-100 kDa. 

Product Applications

Read our Methacrylated Extracellular Matrices eBrochure Here

PhotoGel® Gelatin methacrylate can be used to form cross-linked hydrogels for tissue engineering[1] and 3D printing. The common forms of 3D printing using Lifeink® 300 include extrusion[2][3][4], inkjet[5] and photolithography[6]).

PhotoGel® has been used for endothelial cell morphogenesis,[7] cardiomyocytes,[8] epidermal tissue[9], injectable tissue constructs[10], bone differentiation[11], and cartilage regeneration[12].

Gelatin methacrylate has been explored in drug delivery applications in the form of microspheres[13] and hydrogels[14].
