Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
62 words
A conjugate comprising a Raman label capable of providing a detectable Raman scattering signal for use in a ligand-binding assay for an analyte in a test sample when said label is subjected to radiation capable of inducing a Raman scattering effect wherein said label comprises a Raman active molecule or molecules, wherein said Raman label is attached to a specific binding member.
Claim 2
Dependent Claim
62 words
A conjugate comprising a Raman label capable of providing a detectable Raman scattering signal for use in a ligand-binding assay for an analyte in a test sample when said label is subjected to radiation capable of inducing a Raman scattering effect wherein said label comprises a Raman active molecule or molecules, wherein said Raman label is attached to a specific binding member.
Claim 3
Dependent Claim
17 words
The conjugate of claim 1, wherein the specific binding member is specific for the test sample analyte.
Claim 4
Dependent Claim
18 words
The conjugate of claim 1, wherein the specific binding member is specific for an ancillary specific binding member.
Claim 5
Dependent Claim
32 words
The conjugate of claim 1, wherein the specific binding member is specific for a second specific binding member and wherein the second specific binding member is specific for the test sample analyte.
