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.

Caveolin-1 scaffolding domain peptide

Supplier: Enzo Life Sciences

Cell permeable peptide that blocks eNOS (NOS III) activity and cellular nitric oxide (NO) release in vitro and reduces inflammation and tumorigenesis in vivo. Caveolin-1 interacts with several lipid-modified signalling ligands, such as EGFR, eNOS, G-protein α-subunits, PKCα, H-Ras, and Src, via the C1-SD82-101 sequence.

Human/Mouse Recombinant TGF-B 3 (from E. coli)

Supplier: Shenandoah Biotechnology

Transforming growth factors (TGFs) are multifunctional peptides that regulate growth and differentiation in most cell types. The TGF-β family of proteins signal through serine/threonine kinase receptors. TGF-β isoforms (TGF-β1, -β2, and –β3) have overlapping, yet distinct biological actions in developing and adult tissues. TGF-β3 is an important factor in regulating cell adhesion and accelerating wound repair. TGF-β3 also functions during osteoblast proliferation, chemotaxis, and collagen synthesis.
