This invention relates to a process for the production of remodelable decellularised animal tissue wherein said animal tissue is subjected to decellularisation to obtain decellularised tissue, followed by crosslinking decellularised tissue with glutaraldehyde in phosphate buffered saline to obtain the crosslinked decellularised tissue, followed by treatment of the crosslinked decellularised tissue with heparin and incubation in alcohol to yield the remodelable decellularised animal tissue.
