Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
173 words
Apparatus for use in growing tissue cultures in vitro comprising: a culture vessel comprising an upper surface, a lower surface, a plurality of wells extending from said upper surface to said lower surface, a raised mouth surface extending from said upper surface of each well for supporting a cell culture insert and projecting portions extending from said raised mouth surface of each well for positioning a cell culture insert; and a cell culture insert suspended in one of said wells and comprising an upper portion, a lower portion, a sidewall comprising an inner and outer surface and extending from said upper portion to said lower portion, a permeable membrane attached to said lower portion means for suspending said insert in said one of said wells, and means for restricting, movement of said cell culture insert in said one of said wells of said culture vessel extending from said outer surface of said sidewall wherein said means for suspending is positioned on said raised mouth portion between said projecting portions to position said insert.
Claim 2
Dependent Claim
173 words
Apparatus for use in growing tissue cultures in vitro comprising: a culture vessel comprising an upper surface, a lower surface, a plurality of wells extending from said upper surface to said lower surface, a raised mouth surface extending from said upper surface of each well for supporting a cell culture insert and projecting portions extending from said raised mouth surface of each well for positioning a cell culture insert; and a cell culture insert suspended in one of said wells and comprising an upper portion, a lower portion, a sidewall comprising an inner and outer surface and extending from said upper portion to said lower portion, a permeable membrane attached to said lower portion means for suspending said insert in said one of said wells, and means for restricting, movement of said cell culture insert in said one of said wells of said culture vessel extending from said outer surface of said sidewall wherein said means for suspending is positioned on said raised mouth portion between said projecting portions to position said insert.
Claim 3
Dependent Claim
29 words
The apparatus of claim 1 wherein said projecting portions comprise two projecting portions extending from said raised mouth surface of each well and being located opposite from one another.
Claim 4
Dependent Claim
26 words
The apparatus of claim 1 wherein said culture vessel is substantially rectangular in shape and said wells are in an ordered array of substantially parallel rows.
Claim 5
Dependent Claim
24 words
The apparatus of claim 1 wherein said means for suspending said insert includes at least one discontinuous projecting flange extending from said upper portion.
Claim 6
Dependent Claim
66 words
The apparatus of claim 4 wherein said means for restricting movement of said insert includes at least one projecting tab located on the outer surface of said sidewall and being constructed so as to provide access of sufficient size between said outer sidewall of said insert and the wall of said one of said wells of said culture vessel so as to substantially prohibit capillary activity.
Claim 7
Dependent Claim
28 words
The apparatus of claim 1 wherein said means for suspending said insert includes two discontinuous projecting flanges located opposite from one another and extending from said upper portion.
Claim 8
Dependent Claim
38 words
The apparatus of claim 6 wherein said means for restricting movement of said insert includes two projecting tabs located opposite one another on the outer surface of said sidewall and between said upper portion and said lower portion.
Claim 9
Dependent Claim
36 words
The apparatus of claim 6 wherein said projecting portions of the wells are in an ordered array to substantially prevent the flange of one cell culture insert from contacting the flange of another cell culture insert.
