Calcium trinatrium diethylenetriaminepentaacetic acid hydrate (Ca-DTPA trisodium salt hydrate) is a metal chelator and a useful antidote (such as acute cadmium intoxication).

This is amino acids 427 to 441 fragment belongs to the FliC, serotype a of the S. FliC epitope recognized by a CD4+ T cell from naturally infected C57BL/6 mice is located in a region common to a number of distinct Salmonella serovars such as the S. paratyphi.This dominant epitope is contained within the constant C-terminus of FliC.

The G280-9 peptide, a common melanoma gp100 epitope restricted by MHC-associated HLA-A2. The G280-9 sequence is unique because it could be recognized by cytotoxic T lymphocytes at very low concentrations, however it shows low total immunogenicity that may be attributable to relatively low affinity of this peptide for the HLA-A2.
