Product DescriptionAdvanced BioMatrix offers PhotoCol®, a purified methacrylated Type I bovine collagen kit. PhotoCol® provides native-like 3D collagen gels with the unique attributes to be prepared at various concentrations and crosslinked to provide various gel stiffness.The PhotoCol® kit consists of purified methacrylated Type I bovine collagen as the core component with other support reagents in the kit. Table 1 provides a list of the kit components.

The collagen is extracted from bovine hide and contains a high monomer content.The collagen starting material was isolated from a closed herd and purified using controlled manufacturing processes.A bottle of 20 mM acetic acid solution is provided to solubilize the lyophilized methacrylated collagen at concentrations ranging from 3 to 8 mg/ml. The neutralization solution consists of an alkaline 10X phosphate buffered saline (PBS) solution which provides physiological salts and pH in the final mixture. The photoinitiator consists of Irgacure 2959 to be formulated in methanol (methanol not included) which allows UV crosslinking of the collagen at 365 nm.Parameter, Testing, and MethodMethacrylated Collagen#5198Sterilization MethodFiltrationExtraction MethodAcid - TelocollagenFormLyophilized PowderDegree of Methacrylation>20%Package Size100 mgShelf LifeMinimum of 6 months from date of receiptShelf Life After Reconstitution2 MonthsCollagen Purity - Silver Staining>99%Kinetic Gel Test (Minutes)<40Gel Formation Tube Test (Minutes)< 40Electrophoretic Pattern - Coomassie BlueCharacteristicSterility - USP modifiedNo growthEndotoxin - LAL<10.0 EU/mLSourceBovine HideHydrogel Young's Modulus E (Pa)CharacteristicDirections for UseDownload the full Directions for Use PDFProduct ApplicationsPhotoCol®Methacrylated Collagen is a photocrosslinkable type I collagen for 3D cell culture and bioprinting.As the most abundant protein in the body, collagen is a key component for cell culture. Collagen methacrylate can be used as a rapidly self-assembling type I collagen to form cross-linked hydrogels for tissue engineering[1]. It has been used with mesenchymal stem cells[2], fibroblasts, adipose derived stem cells, epithelial cells, and many more.Collagen methacrylate is useful for forming scaffolds with varying degree of stiffness, by altering collagen concentration or the dose of UV-light exposure[2]. It is also being extensively characterized for its usefulness in 3D bioprinting (extrusion, inkjet, and photolithographic[3]).PhotoCol® has been used for created 3D microniches[4], as well as for 3D bioprinting human corneas[5].References:https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4172302/https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4243547/http://www.worldscientific.com/doi/abs/10.1142/S2339547817500091 https://onlinelibrary.wiley.com/doi/abs/10.1002/adbi.201700237https://www.ncbi.nlm.nih.gov/pubmed/29772228 Product ReferencesReferences for PhotoCol®:Isaacson, A., Swioklo, S. & Connon, C.
