PhotoCol®-LAP is a methacrylated Type I collagen kit.These 3D collagen gels can be prepared at various concentrations and photocrosslinked (405nm) to provide various gel stiffness. Each kit contains 100 mg of methacrylated collagen, LAP photoinitiator, acetic acid and a neutralization solution.
Advanced 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.
The methacrylated Type I collagen is produced from telo-peptide intact bovine collagen where the collagen has been modified by reacting the free amines, primarily the e-amines groups of the lysine residues as well as the a-amines groups on the N-termini. > 20% of the total lysine residues of the collagen molecule have been methacrylated. 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 LAP to be formulated in 1X cell culture media or PBS which allows blue light photocrosslinking of the collagen at 405 nm.
To sterile filter, resuspend and filter through a 0.2 micron button filter.
