Product Description

Advance biomatrix offers PhotoSericin®, a purified and lyophilized methacrylated sericin powder for photocrosslinkable hydrogels. PhotoSericin® is a highly versatile solution designed for researchers and scientists seeking advanced materials for tissue engineering, drug delivery, and regenerative medicine applications. PhotoSericin® provides 3D tunable gels with the unique attributes to be prepared at various concentrations and crosslinked to provide various gel stiffnesses.

PhotoSericin® is offered in convenient kits that include a selected photoinitiator, provided separately as a powder. This allows for customization and precise control over the crosslinking process.



Catalog Number

Photoinitiator Included




PhotoSericin with LAP


LAP (405nm)

PhotoSericin with Ruthenium


Ruthenium (400-450nm)


PhotoSericin® is produced from sericin that has been modified by reacting the hydroxyl groups of sericin with the methacrylate functional groups, forming a strong covalent bond.
