carrier molecule

a molecule that is lipid-soluble and carries other molecules with a lower mobility within biological membranes. see ACTIVE TRANSPORT. Carrier molecules in ELECTRON TRANSPORT SYSTEMS in respiration and photosynthesis carry electrons and in turn are capable of oxidation and reduction.

HBsAg-S gene has been applied as a large carrier molecule to improve the immunogenicity of DNA vaccines (Gonzalez et al., 2009; Kotiw et al., 2012).
Stellar Biotechnologies Inc is the leader in sustainable manufacture of Keyhole Limpet Hemocyanin (KLH), an immune-stimulating protein utilized as a carrier molecule in therapeutic vaccine pipelines (targeting cancers, immune disorders, Alzheimer's and inflammatory diseases) and for assessing immune system function.
Oakes, Stellar's Chairman of the Board, President and CEO: "We would like to extend our congratulations to Neovacs on the encouraging results achieved in its Phase 2b study and on the continuing advancement of their IFN-Alpha-Kinoid immunotherapy in systemic lupus erythematosus, which the Lupus Foundation has described as 'one of the world's cruelest, most unpredictable and devastating diseases.' In addition to achieving key endpoints, Neovacs reported potent and long-lasting biological activity of their therapeutic vaccine, which utilizes Stellar KLH as a carrier molecule. The KLH-conjugated vaccine also demonstrated a favorable safety profile among study participants.
It may be possible to produce high-antibody titers against hapten-structured proteins without using any protein carrier molecule when using alternative adjuvant systems.
Along with ADP, the anticancer response of a PS can further be enhanced using a carrier molecule. Carrier molecules in the form of nanoparticles (NPs) can accumulate in a tumour because of the well-known enhanced permeability retention (EPR) effect.
Investigators have succeeded in reducing relative mRNA expression and mitigating disease phenotypes through either high-dose siRNA administration without a carrier molecule or using lower doses bound to nanoparticles [15-18].
