48. A composition for detecting analyte of interest in a sample comprising:
(A)k, (B)u, (C), (D)xwherein A is at least one ECL moiety which can be induced to repeatedly emit electromagnetic radiation by direct exposure to an electrochemical energy source;
B is at least one first carrier containing A, wherein A can be released from B and B is either linked to (1) an analog of the analyte of interest;
or(2) to a first specific binding partner of the analyte of interest;
C is the sample which may contain the analyte of interest; and
D is at least one second carrier and is either linked to (3) the analog of the analyte of interest;
or(4) a second specific binding partner of the analyte of interest;
wherein k, u, and x are each an integer equal to or greater than 1, provided that B and D are not both linked to the analog of the analyte of interest, and provided that if B is linked to the analog of the analvte of interest, then D is linked to the second specific binding partner and if D is linked to the analog of the analyte of interest, then B is linked to the first specific binding partner. - View Dependent Claims (49, 50, 52, 53, 56, 61, 62, 63, 64, 65, 66, 67, 68, 69, 71, 73, 77, 85, 205, 206, 207, 208, 209, 210, 211, 212, 213, 214, 215, 219, 220, 222)

186. A kit for detecting an analyte of interest in a sample, comprising
at least one ECL moiety which can be induced to repeatedly emit electromagnetic radiation by direct exposure to an electrochemical energy source; -
at least one first carrier containing the ECL moiety, wherein the ECL moiety can be released from the first carrier and the first carrier is either linked to (1) an analog of the analyte of interest;
or(2) a first specific binding partner of the analyte of interest;
at least one second carrier which is either linked to (3) the analog of the analvte of interest;
or(4) a second specific binding partner of the analyte of interest;
provided that the first carrier and the second carrier are not both linked to the analog of the analyte of interest, andprovided that if the first carrier is linked to the analog of the analvte of interest, then the second carrier is linked to the second specific binding partner and if the second carrier is linked to the analog of the analyte of interest, then the first carrier is linked to the first specific binding partner. - View Dependent Claims (187, 188, 189, 190, 191, 193, 194, 196, 216, 217, 218, 221, 223)
