<p>Amylin is a hormone that regulates the release of insulin from the pancreas. Amylin is a protein that consists of 39 amino acids, and in its natural form it is not soluble in water. The amyloid fibrils are insoluble aggregates of proteins that can be found in the brain tissue of patients with Alzheimer's disease. Amylin has been shown to have an entrapment efficiency greater than 96% by using polymeric particles with a diameter less than 50 microns. These particles are able to increase water solubility and nutrient metabolism, as well as improve evaporation rates. They also provide an increased surface area for absorption and pharmacological properties. Amylin has been shown to lower postprandial glycemia when used with insulin in type II diabetes mellitus patients, and may also be an anorectic agent.</p>

Peptide M is a synthetic peptide made up of the amino acid sequence: DTNLASSTIIKEGIDKTV. It is an immunogenic component corresponding to amino acids 303-320 of the photoreceptor cell protein, retinal S-antigen. During studies, it has been found to induce experimental autoimmune uveitis (EAU) in animals which is a T-cell mediated disease causing retina, pineal gland and uveal tract inflammation. EAU successfully models ocular autoimmune diseases such as birdshot retinochoroidopathy and sympathetic ophthalmia. Therefore peptide M can be used in research into these diseases. Structural studies have demonstrated peptide M to form macromolecular assemblies and then an intermolecular beta-sheet structure between a pH range of 4-9.5. It has been suggested, that when the peptide M adopts the monomeric state its structure and beta sheets become disordered. It is also thought that through its extended beta-type conformation peptide M is able to position itself between the major histocompatibility complex and the T-cell receptor.

D-Val-Leu-Lys-p-nitroanilide is a selective colorimetric substrate for plasmin used to determine plasmin formation from plasminogen in amidolytic activity assays and plasminogen activating assays. Plasmin is a plasma serine protease whose main role is to dissolve fibrin blood clots. After cleavage by plasmin, the protease activity is quantified by the release of p-nitroaniline (pNA) from the substrate.
