Human amyloid-beta (1-40) peptide
Supplier: Cayman Chemical
Amyloid-β (1-40) peptide Aβ (1-40) is a 40-residue protein fragment of the C-terminal portion of the β-amyloid protein implicated in Alzheimer’s disease. Aβ (1-40) is more abundant, less neurotoxic, and does not form oligomers as easily as amyloid-β (1-42) peptide (Aβ (1-42).

Poly-L-lysine hydrobromide
Supplier: SIGMA ALDRICH MICROSCOPY
Poly-L-lysine is a positively charged amino acid polymer with approximately one HBr per lysine residue. The hydrobromide allows the poly-L-lysine to be in a crystalline form soluble in water. A small amount of product may be found in the beta structure because the HBr interferes with hydrogen bonding between amino and either the carboxyl groups or N or O containing moieties.

Human Recombinant NAP-2 (from E. coli)
Supplier: Shenandoah Biotechnology
Neutrophil activating peptide 2 (NAP-2), also known as CXCL7, is a member of the CXC family of chemokines. NAP-2 is a carboxyl-terminal fragment produced by proteolytic cleavage of the platelet basic protein (PBP). NAP-2 is released from platelets and binds to the receptors CXCR1 and CXCR2 to chemoattract and activate neutrophils during inflammatory events.

Anabaenopeptin A (from Microcystis aeruginosa)
Supplier: ENZO LIFE SCIENCES
Anabaenopeptins are a highly diverse group of bioactive peptides produced by several genera of cyanobacteria such as Anabaena, Planktothrix, Microcystis and Nodularia. These peptides are commonly detected in cyanobacterial blooms along with the well known microcystins. Unique cyclic peptides where lysine is conserved in position 2 and cyclisation is achieved by linkage of the lysine to the C-terminal amino acid. In addition the side chain of a single amino acid is attached via a ureido bond. Bioactive peptides originally isolated from Anabaena flos-aquae NRC 525-17 where they were shown to be non-toxic in mice but had dose dependant relaxations in rat aortic preparations with endothelium precontracted with 0.1µM norpinephrine.
Anabaenopeptins inhibit protein phosphatase.
