Proton dependent oligopeptide transporter (POT) proteins is a family of proteins that is also known as the peptide transport (PTR) protein family. These are made up of energy-dependent transporter proteins that are commonly found in bacteria and humans. These POT proteins are nitrate permease and have the ability to transport histidine and peptides. ELISA stands for enzyme-linked immunosorbent assay. These assays are plate based and are used for quantification and detection of a number of substances including peptides, proteins, antibodies and hormones. The ELISA POT assay kits are ELISA based assay kits used to quantify and identify POT proteins and its ligands. Some of the human proteins used in the ELISA POT assay kits include SLC15A1, SLC15A2, SLC15A4 and others. The use of ELISA POT assay kits have a number of applications and can be potentially used for design and delivery of drugs. The ELISA POT assay kits can also be used for pharmacokinetic studies as well.
