Peptides

<p>Peptide substrate for the kallikrein-related peptidase 7 (KLK7), the most abundant KLK family protease in the stratum corneum (outermost layer of the epidermis). KLK family have been implicated in several key homeostatic processes and in skin diseases that feature impaired desquamation. Increased levels of KLK7, have been identified in the stratum corneum of patients with atopic dermatitis (AD). T-helper type 2 cytokines, including interleukin 4 (IL-4) and-IL-13, can stimulate expression of KLK7, suggesting a direct link between inflammation in AD and KLK7 levels.KLK7 cleaves its substrates after tyrosine or phenylalanine residues. This peptide contains a C-terminal 7-amino-4-methylcoumarin (AMC) fluorescent tag, which is quenched when linked to the peptide via the amide bond. AMC is cleaved from the peptide by KLK7, upon cleavage the AMC fluorescence is activated.</p>

<p>Highly specific protein tag that can be added to a protein using recombinant DNA technology. FLAG is an artificial antigen to which high affinity monoclonal antibodies have been raised, therefore allowing for highly effective protein purification by affinity chromatography as well as accurate localisation of FLAG tagged proteins within living cells, or Western blots. FLAG peptide can be used to effectively purify complexes with multiple proteins as its mild purification procedure tends not to disrupt such complexes. It can be used to obtain proteins of sufficient purity for x-ray crystallography.</p>

<p>Tetanus Toxin (1084-1099) is a protein that is derived from the single-chain polypeptide neurotoxin produced by Clostridium tetani. The neurotoxins produced by Clostridium tetani are among the most potent molecules known to humankind. Once in the body, the toxin binds to the basal lamina at the neuromuscular junction. From here, the toxin is transported to inhibitory interneurons in the spinal cord, where it prevents the release of neurotransmitters, which causes spastic paralysis.</p>

<p>Substrate peptide for C-terminal Src kinase (Csk) for use in kinase assays. Csk is a cytosolic tyrosine kinase that is closely related to the kinase Src and is a well-known negative regulator of Src family kinases. Csk has both tumour suppressor and oncogenic properties and has also been implicated in regulating blood pressure, making Csk a novel therapeutic target for hypertension disorders.</p>

<p>Cecropins are a lytic peptide family, originally isolated from Hyalophora cecropia. Cecropin-B is a cationic helical peptide that can form pores, this is believed to be the reason for its such potent lytic activity. Cecropin-B has been shown to be effective against both Gram-positive and Gram-negative bacteria plus numerous cancer cell lines including multidrug-resistant types. The ability to insert into the cell membrane and lead to pore formation is attributed to the amphipathic groups present creating amphipathic regions. The effectiveness of cecropin-B on cancer cells has led to further use of the peptide as a model for potential new anticancer drugs including cyclic cationic forms.</p>

<p>Vascular lipid deposition and altered lipid profiles are typical when unregulated angiogenesis is occurring, it is often seen in vascular disorders such as cancer and atherosclerosis. Apolipoprotein a (ApoA) functions as part of the lipid transporter complex high-density lipoproteins (HDL) to ensure lipid homeostasis and therefore the balance of angiogenesis. Within ApoA the Kringle5 (KV) domain (67 - 77), also known as KV11, has been identified as the region of ApoA that exerts anti-angiogenic effect. KV11 was shown in tumour cells to inhibit angiogenesis and consequently inhibits tumour progression. KV11 targets the angiogenesis c-Src/ERK pathway by blocking the activation signals received from vascular endothelial growth factor (VEGF). KV11 provides a new research potential for an anti-angiogenesis and anti-tumour therapeutic agent.</p>
