Multiwell instrument
A multiwell instrument includes a vessel having an inside; a plurality of culture plates arranged in the inside of the vessel, each individual one of the plurality of culture plates having an inside in which material to be examined can be stored; and filters disposed inside the respective culture plates to partition the insides of the respective culture plates into at least two wells which are horizontally adjacent.
1. A multiwell instrument comprising:
a vessel having an inside;
a plurality of culture plates arranged in the inside of the vessel, each individual one itself of the plurality of culture plates having an inside in which biomaterial to be cultured and examined can be stored; and
boundary portions disposed inside the respective culture plates to partition the insides of the respective culture plates into at least two wells which are horizontally adjacent,
wherein each of the boundary portions comprises a filter with a hole diameter of 5 μm or less, and a step is formed between a surface of the boundary portion and a surface of the filter,
wherein the filter is configured: (i) not to allow the biomaterial to pass through; and (ii) to allow a specific substance secreted from the biomaterial to pass through, and
wherein each of the boundary portions and each of the culture plates in which each of the boundary portions is disposed are molded into a single piece.
2. A method for performing screening of a biomaterial by using the multiwell instrument according to claim 1 .
3. A method for performing screening of a substance secreted from a biomaterial by using the multiwell instrument according to claim 1 .
4. A method comprising:
disposing a biomaterial in a first of two adjacent wells in the multiwell instrument according to claim 1 ;
disposing one of the filters that is configured to allow the specific substance secreted from the biomaterial to pass through, between the two adjacent wells, wherein the specific substance is a first substance; and
disposing a second substance that is able to chemically bind to the first substance in a second of the two adjacent wells.
5. The method according to claim 4 , wherein screening is performed by setting the two adjacent wells as a pair, and using the multiwell instrument in which a plurality of the pairs are arranged.
6. A multiwell instrument comprising:
a vessel having an inside;
a plurality of culture plates arranged in the inside of the vessel, each individual one itself of the plurality of culture plates having an inside in which biomaterial to be cultured and examined can be stored; and
boundary portions disposed inside the respective culture plates to partition the insides of the respective culture plates into at least two wells which are horizontally adjacent,
wherein each of the boundary portions comprises a filter,
wherein the filter is configured: (i) not to allow the biomaterial to pass through; and (ii) to allow a specific substance secreted from the biomaterial to pass through, and
wherein the culture plates are spaced apart inside the vessel such that there is an empty space or void between each adjacent pair of the culture plates.
7. A method for performing screening of a biomaterial by using the multiwell instrument according to claim 6 .
8. A method for performing screening of a substance secreted from a biomaterial by using the multiwell instrument according to claim 6 .
9. A method comprising:
disposing a biomaterial in a first of two adjacent wells in the multiwell instrument according to claim 6 ;
disposing one of the filters that is configured to allow the specific substance secreted from the biomaterial to pass through, between the two adjacent wells, wherein the specific substance is a first substance; and
disposing a second substance that is able to chemically bind to the first substance in a second of the two adjacent wells.
10. The method according to claim 9 , wherein screening is performed by setting the two adjacent wells as a pair, and using the multiwell instrument in which a plurality of the pairs are arranged.
