Recombinant collagenases with a stable specific activity and enzyme agents for cell and tissue dissociation such a recombinant are provided. The recombinant collagenase is derived from Grimontia hollisae -derived collagenase is characterized by having, from the N terminus to the C terminus, a collagenase catalytic domain, a linker region sequence, and a prepeptidase C terminal domain, which Grimontia hollisae -derived recombinant collagenase does not comprise at least the prepeptidase C terminal domain. The obtained recombinant collagenase has a high and stable specific activity.

An object of the present invention is to provide a method of producing a fine polymer gel, which can produce the gel in large quantities in a short period of time in a very simple manner without the need for large-scale facilities. The present invention provides a method of producing a microstructured gel in a shape in accordance with a pattern, the method comprising the steps of: dropping a polymerizable monomer aqueous solution containing a polymerizable monomer component onto a portion of a surface of a substrate having a pattern comprising a fine groove in the surface; moving by capillary action the polymerizable monomer aqueous solution along the groove constituting the pattern; and subjecting the polymerizable monomer aqueous solution in the groove to polymerization.

The present invention addresses the problem of providing, as a scaffold material, a cell culture gel that utilizes plasma from adult bovine blood, rather than using extracellular matrix. The present invention further addresses the problem of producing cells using, as the scaffold material for cell culture, a cell culture gel that utilizes plasma from adult bovine blood. The cell culture gel according to the present invention contains: plasma derived from adult bovine blood, and a coagulant.
