Sodium L-lactate is produced from pyruvate by the enzyme Lactate Dehydrogenase. Lactate production occurs during anaerobic glycolysis or in proliferatively active cells. L-Lactic Acid occurs in small quantities in the blood and muscle fluid of man and animals.

HO-PEG13-OH is a PEG-based PROTAC linker that can be used in the synthesis of PROTACs.

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.
