    摘要: An insert device and co-culture device assembly incorporating the insert device, which includes an insert chamber with two fluid impermeable side walls that extend from a microporous bottom to an open top to form an inner cavity. The first side wall is shaped to form a convex arc that follows between about half of a circumference of the well and less than an entire circumference of the well. The second side wall joins ends of the first side wall and protrudes inward towards a center of the convex arc. A flange extends outward from or beneath the top and is notched to form a gap adjacent to the second side wall, which forms an access port allowing access to the lower chamber with a micropipette tip when the insert device is inserted into a well of a single or multi-well plate.

The methods include the steps of providing a cell suspension or a cell lysate containing cell components, adding a chromogenic substrate at the start of the enzyme reaction, adding a first additional substance to stop the enzyme reaction, and making a colorimetric measurement, wherein a second additional substance which reduces the light scattering and/or absorption caused by the cells or the cell components is added during or after termination of the enzyme reaction. In particular, a method is disclosed wherein the enzyme is lactate dehydrogenase (LDH) and the first additional substance to stop the reaction is HCl.
