A cantilever for measuring intra-cellular and inter-cellular microspaces of the present invention includes a support portion, a lever portion provided to the support portion so as to protrude therefrom, and a probe portion provided near a free end of the lever portion. The probe portion includes a conductive probe made of a carbon-based material, and an insulating film to coat a periphery of the conductive probe.

Cantilever for measuring intra-cellular and inter-cellular microspaces

A continuous temperature-gradient incubation apparatus designed to solve the problem of moving of liquid vapor generated on the high-temperature side toward the low-temperature side to thereby cause condensation. There is provided a multiwell incubation apparatus having a well-housing vessel made of a heat conducting material and, detachably housed therein, liquid-storing wells, the wells being arranged in transverse rows and longitudinal rows, the multiwell incubation apparatus being also provided with a liquid or gas flow channel or bath for supply of a gas saturated with vapor of the liquid, the multiwell incubation apparatus being capable of maintaining incubation temperatures differing between individual transverse rows of wells with a predetermined temperature difference, so as to realize a temperature series which forms a predetermined temperature difference profile along the longitudinal rows, characterized in that the multiwell incubation apparatus includes a heat source for realizing a temperature which is the lowest in the given temperature series, the heat source being disposed outside the well rows and along the transversely lined up wells close to a first side of the housing vessel; another heat source for realizing a temperature which is the highest in the given temperature series, the heat source being disposed outside the well rows and along a side opposite to the first side; and a separator provided for each transverse row of a certain temperature.

The present invention relates in providing a process for recovering a soluble protein having a higher recovery rate by suppressing the aggregation of the protein when a denaturing agent is removed from the solubilization treatment solution containing a solubilized protein; and providing a process for removing a denaturing agent from the above solubilization treatment solution in which the aggregation of the protein is suppressed. In a process for recovering a soluble protein comprising the steps of removing a denaturing agent from a solubilization treatment solution prepared by solubilizing insoluble protein aggregates using the denaturing agent, the process of the present invention is characterized by subjecting the solubilization treatment solution to a treatment of removing the denaturing agent in the presence of a dihydric to tetrahydric, polyhydric alcohol at a concentration of 60 to 99% by volume, and thereafter diluting with a diluent solution the treatment solution obtained after the removal treatment.
