Peptide-based imaging agents are small molecules that possess favourable properties such as rapid diffusion in target tissue, rapid clearance from the blood circulation and non-target tissues, easy and low-cost synthesis, and low toxicity and immunogenicity.
Semiconductor oxides with hierarchically hollow architecture can provide significant advantages as sensing materials for gas sensing by facilitating the diffusion of target gases and the surface reaction.
As small peptides for receptor imaging and targeted radiotherapy have advantages over proteins, antibodies and antibody fragments as they are small and show rapid diffusion in target tissue and they have low molecular weight which will result in rapid clearance from blood and non-target tissues and that in turn will result in high tumor-to-background ratios.
Due to their small size, peptides show rapid diffusion in target tissue.
Peptides are small molecules and show rapid diffusion in target tissue.
More importantly, because of their hollow structure, the affinity carbon shells of the MHM affinity microspheres have numerous relatively large but shallow open pores, which would facilitate the mass transport and diffusion of target biomolecules.
A recently developed computational model of particokinetics (sedimentation, diffusion) and target cell dosimetry for in vitro systems addressed this issue (Hinderliter et al. 2010) and could be used to calculate dose rates and target cell doses to compare with the total assay exposure time.
Approximately 1.5 2.0 % of the total Cr and PCr pool is degraded daily via simple non-enzymatic chemical dehydration to creatinine, which is lost from cells by diffusion and targeted for urinary excretion [22].
More specific formulation aspects include optimal retention time, appropriate drug diffusion, and targeted drug delivery.
Her former employer, Mizrahi, may be the best example of designer diffusion success at Target.
