Abstract

Official abstract text for this publication.

The present disclosure provides compositions and methods based on peptide-detectable agent conjugates that are useful for imaging beta cell mass.

First claim

Opening claim text (preview).

What is claimed is: 1. A composition comprising the peptide sequence SEQ ID NO:2, wherein the amino acid at position 12 is an unnatural amino acid, wherein the unnatural amino acid is (S)-2-amino-4-pentynoic acid. 2. A composition comprising the peptide sequence SEQ ID NO:3, wherein the amino acid at position 12 is cysteine. 3. The composition of claim 2 , wherein the cysteine is modified with a linker comprising a maleimide at a first end and a tetrazine at a second end. 4. The composition of claim 3 , wherein the cysteine has reacted with the maleimide via a 1,2-addition reaction. 5. The composition of claim 3 , wherein the tetrazine has reacted with a strained alkene attached to a detectable agent via an inverse electron demand Diels-Alder reaction. 6. The composition of claim 5 , wherein the strained alkene is trans-cyclooctene.
