Claims Analysis

Total Claims: 18
Claim 1
Independent Claim 143 words
A kit for use in quantitation of specimen cell objects on each of a plurality of slide, the kit comprising: a microscopic slide, the slide including a reference material are, the reference material area containing a reference means for staining, the reference means having predetermined physical characteristics which are detectable after staining; one or more containers of stain material, the stain material including stain for stain application to the reference means and to specimen cell objects on the plurality of slides, the stain in the containers being in an effective amount to provide an optical density to the reference means after simultaneous staining of the reference means and specimen cell objects so that after the staining, the optical density of the reference means may be compared with an optical density of the specimen cell objects for the quantitation of the specimen cell objects.
Claim 2
Dependent Claim 143 words
A kit for use in quantitation of specimen cell objects on each of a plurality of slide, the kit comprising: a microscopic slide, the slide including a reference material are, the reference material area containing a reference means for staining, the reference means having predetermined physical characteristics which are detectable after staining; one or more containers of stain material, the stain material including stain for stain application to the reference means and to specimen cell objects on the plurality of slides, the stain in the containers being in an effective amount to provide an optical density to the reference means after simultaneous staining of the reference means and specimen cell objects so that after the staining, the optical density of the reference means may be compared with an optical density of the specimen cell objects for the quantitation of the specimen cell objects.
Claim 3
Dependent Claim 45 words

Claim 4
Dependent Claim 38 words
A kit as recited in claims 1 or 2 wherein the reference means includes a reference material selected from the group consisting of rat liver nuclei, trout erythrocytes, chicken erythrocytes, dried DNA, cultured cell lines and mixtures thereof.
Claim 5
Dependent Claim 18 words
A kit as recited in claims 1 or 2 wherein the kit further includes a stain sulfonating agent.
Claim 6

Claim 7
Dependent Claim 136 words
A kit for the quantitation of cell nuclei comprising: a microscopic slide, the slide including a reference area and a specimen call object area for receipt of specimen cell objects, the reference area containing a reference means for staining, the reference means having predetermined physical characteristics which are detectable after staining; and one or more containers of stain material, the stain application to the specimen cell objects and the reference means, the stain in the containers being in an effective amount to provide an optical density to the reference means after simultaneous staining of the reference means and specimen cell objects so that after the staining, the optical density of the reference means may be compared with an optical density of the specimen cell objects for the quantitation of cell nuclei in the specimen cell objects.
Claim 8
Dependent Claim 136 words
A kit for the quantitation of cell nuclei comprising: a microscopic slide, the slide including a reference area and a specimen call object area for receipt of specimen cell objects, the reference area containing a reference means for staining, the reference means having predetermined physical characteristics which are detectable after staining; and one or more containers of stain material, the stain application to the specimen cell objects and the reference means, the stain in the containers being in an effective amount to provide an optical density to the reference means after simultaneous staining of the reference means and specimen cell objects so that after the staining, the optical density of the reference means may be compared with an optical density of the specimen cell objects for the quantitation of cell nuclei in the specimen cell objects.
