Claims Analysis

Total Claims: 7
Claim 1
Independent Claim 56 words
An antigen prepared by a process, consisting essentially of: reacting a catecholamine with a protein or polypeptide carrier and an aldehyde via the Mannich reaction such that said catecholamine is attached through a substituted or unsubstituted methylene linkage to an amine group of said carrier at an unsubstituted position on the phenyl nucleus of said catecholamine.
Claim 2
Dependent Claim 56 words
An antigen prepared by a process, consisting essentially of: reacting a catecholamine with a protein or polypeptide carrier and an aldehyde via the Mannich reaction such that said catecholamine is attached through a substituted or unsubstituted methylene linkage to an amine group of said carrier at an unsubstituted position on the phenyl nucleus of said catecholamine.
Claim 3
Dependent Claim 20 words
The antigen of claim 1, wherein the catecholamine is selected from the group consisting of epinephrine, norepinephrine, dopamine and dopa.
Claim 4
Dependent Claim 12 words
The antigen of claim 1, wherein the protein is bovine serum albumin.
Claim 5
Dependent Claim 36 words
A process for producing a catecholamine specific antibody, which comprises: injecting an antigen prepared by the process of claim 1 into a host animal; withdrawing blood from said injected animal; and isolating said catecholamine specific antibodies.
Claim 6
Dependent Claim 26 words
The process of claim 4, wherein the host animal is selected from the group consisting of cows, horses, sheep, goats, pigs, guinea pigs, rats and rabbits.
Claim 7
Dependent Claim 11 words
The catecholamine specific antibody produced by a process of claim 4.
