Galanin is a widely distributed neuropeptide in the central nervous system, peripheral regions and endocrine system. Galanin has a role in energy homeostasis. Central injections of galanin to the amygdala led to food intake in rats. Galanin also acts in the CNS to inhibit neurotransmitter release, such as acetylcholine. Galanin has been implicated in numerous neurological conditions, including Alzheimer's disease, depression, and epilepsy.Galanin interacts with 3 receptor subtypes, GalR1-3 which are G protein-coupled receptors inserted into the plasma membrane. GalR1 is believed to activate a Gβγ pathway to regulate MAPK activation. GalR2 can also activate the MAPK pathway, but unlike GalR1, there is detectable inositol phosphate production. GalR3 is associated with the Galphai/o pathway. Activation of the receptor leads to a cellular influx of potassium ions.The galanin active fragment (1-16) has been identified as a highly potent agonist for the galanin receptors.  These have become a basis for galanin-based peptides, which are neuroactive. These are being investigated as a potential source for anticonvulsant neuropeptides as a therapeutic for conditions such as epilepsy. A library of galanin fragments has allowed screening of their properties to be assessed and used to generate chimeric peptides. Galanin fragments have different affinities for GalR receptors- however, the N-terminal (1-16) have been shown to have a conserved affinity for the receptors.The galanin fragment (2-13) provided here have a C-terminal biotin label for easy detection and purification.

Pan HLA DR-binding epitope (PADRE) is a universal peptide that activates CD4+ T cells which can be used as an agonist adjuvant.

This peptide represents the reserve sequence of β-amyloid 25-35 (Aβ 25-35) and is used as an inactive control peptide.Aβ has been identified as the key subunit of the extracellular plaques found in the brains of patients with Alzheimer disease (AD) and Down syndrome (DS). Aβ has therefore been extensively studied as a potential target for treatment of AD.Aβ is formed from the cleavage of the large, transmembrane protein- APP (amyloid precursor protein). Cleavage of APP by β- and then γ-secretases results in the formation of Aβ. Aβ can aggregate to produce amyloid-β oligomers, which are thought to be highly neurotoxic. Over time Aβ can further aggregate to produce the characteristic senile plaques present in AD and DS. Aβ can be degraded by enzymes such as neprilysin, insulin degrading enzyme or endothelin converting enzyme. At physiological levels Aβ may be involved in controlling synaptic activity and neuronal survival.

This anti-microbial peptide (AMP) has been shown to cause lysis of several human cancer cell lines. Macropin-2 is most potent against CCRF-CEM T lymphoblastoid (human acute lymphoblastic leukemia) cells. At higher concentrations Macropin-2 also causes lysis of human umbilical vein endothelial cells (HUVEC), rat intestinal epithelial cells (IEC), human cervix carcinoma (HeLa) cells and human colon adenocarcinoma (SW480). Macropin-1 is also available in our catalogue.
