Tricine can clearly visualize tumors, may as melanoma imaging agents. Using the combination of tricine and a phosphine ligand, HYNIC-derivatized peptides or other small molecules can be labeled with 99mTc in high specific activity and with high stability for potential use as radiopharmaceuticals.

Antennapedia Peptide is a 16 amino acid peptide corresponding to the region within the Drosophila Antennapedia DNA binding domain that is mapped to be responsible for cellular internalization.

Threonine is an essential amino acid in humans. It is abundant in human plasma particularly in newborns. Severe deficiency of threonine causes neurological dysfunction and lameness in experimental animals. Threonine is an immunostimulant which promotes the growth of thymus gland. It also can probably promote cell immune defense function.
