Functional Peptides

Antimicrobial Peptides

Antimicrobial peptides (AMPs), also called host defense peptides (HDPs), which commonly content 5-40 amino acids, are natural antibiotics produced by various organisms. Creative Peptides can offer a wide range of AMPs to fully support your project.

Cell Penetrating Peptides

Creative Peptides is an experienced company which has supplied a variety of CPPs over years. We have synthesized numerous commonly used CPPs and we also provide special CPPs composed of unusual or non-natural amino acids. Unless otherwise specified, all peptides have >95% purity and contain TFA (trifluoroacetic acid) as counter-ions.

Chelate Peptides (DOTA related peptides)

DOTA is used as a complexing agent in medical applications as contrast agents and cancer treatments for example in positron emission tomography. Complexes of DOTA peptides, depending on the metal ion, have found applications in three major areas: magnetic resonance imaging [GdIII), Eu(III)], nuclear imaging [¹¹¹In(III), ⁶⁸Ga(III), ^64/67Cu(II)], and therapeutic radiopharmaceuticals [⁹⁰Y(III), ¹⁷⁷Lu(III)].

MHC-Peptide Tetramer

MHC-peptide tetramers are complexes consisting of four fluorophore-labeled major histocompatibility complex (MHC) molecules, the individual monomer of which binds a specific peptide respectively, are usually used in MHC tetramer assay for direct visualization and quantification of antigen-specific T cells.
