Abstract
Abstract Methine dyes which inhibit cell growth are identified by (1) determining the reduction potential of the dye, (2) determining the ability of the dye to sorb to the cells and (3) selecting those dyes which have a reduction potential more negative than about -0.8 volt and which are sorbed to the cells.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
66 words
A process for selecting methine dyes which inhibit cell growth, the process comprising (1) determining the reduction potential (E R ) of the dyes, (2) determining the ability of the dyes to bind to the cells and (3) selecting those dyes which have a reduction potential more negative than about 31 0.8 volt and which bind to the cells to the extent of 10% or greater.
Claim 2
Dependent Claim
66 words
A process for selecting methine dyes which inhibit cell growth, the process comprising (1) determining the reduction potential (E R ) of the dyes, (2) determining the ability of the dyes to bind to the cells and (3) selecting those dyes which have a reduction potential more negative than about 31 0.8 volt and which bind to the cells to the extent of 10% or greater.
Claim 3
Dependent Claim
19 words
A process of claim 1 wherein the dyes selected have a reduction potential more negative than about -1.0 volt.
Claim 4
Dependent Claim
12 words
A process of claim 1 wherein the dyes selected are cyanine dyes.
Claim 5
Dependent Claim
17 words
A process of claim 1 wherein the dyes are selected to inhibit the growth of procaryotic cells.
Claim 6
Dependent Claim
17 words
A process of claim 1 wherein the dyes are selected to inhibit the growth of eucaryotic cells.
Claim 7
Dependent Claim
32 words
A process for inhibiting cell growth comprising the steps of: (1) selecting a dye by the process of claim 1, and (2) contacting the cells to be inhibited with the selected type.
Claim 8
Dependent Claim
33 words
