Palmitoyl GHK tripeptide
The GHK tripeptide has many attributes which can positively impact human health. GHK can improve tissue repair, exhibit anti-cancer and anti-inflammatory properties, suppress age related molecules and restore chronic obstructive pulmonary disease fibroblasts.The GHK tripeptide is found in the human plasma and binds copper. It exerts its effects through its ability to up regulate and downregulate 4,000 human genes. Due to its ability to protect and regenerate aspects of human health, GHK-Cu can be used in products for skin and hair.Specifically during skin regeneration GHK-Cu can promote the synthesis of collagen and glycosa-minoglycans, increase the rate of wound healing and the formation of blood vessels.A palmitoyl group is present on the N-terminus.Peso molecular:578.4 g/molLys-Gly-Ala-Ile-Ile-Gly-Leu-Met-Val-Gly-Gly-Val-Va

β-Amyloid (12-20)
Aβ has been identified as the key subunit of the extracellular plaques found in the brains of patients with Alzheimer's disease (AD) and Down's 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.Forma y color:PowderPeso molecular:1,153.6 g/molH-TTPPVLDSDGSFFLYSK-OH

GRGD-acid is a cell adhesive peptide containing the RGD motif. This enables it the ability to increase cell adhesion and rates of cell growth, differentiation and proliferation.When immobilised onto a Poly(etheretherketone) (PEEK) surface it has been shown to increase cell adhesion and proliferation in MC3T3-E1 cells. GRGD could therefore be used in dental implants.This peptide contains a C-terminal Alexa Fluor 647 florescent dye. A cysteine residue has been added to the C-terminus for conjugation of the dye via the cysteine thiol moiety. AF647 is a bright, far-red-fluorescent dye with excitation between 594 nm and 633 nm, and is pH-insensitive over a wide molar range.Forma y color:PowderPeso molecular:1,486.2 g/molBiot-KKKKEEIYFFF-OH

Ac-GPLD-[Rh110]-[D-Pro]
Fluorogenic substrate peptide to assay the caspase-like peptidic activity of the 20S proteasome. In its intact state this peptide is non-fluorescent, however when the Rhodamine fluorophore is released upon hydrolysation, fluorescence can be detected. This peptide is therefore a useful tool for analysing enzyme activity.The presence of the D-proline residue on the C terminal of the rhodamine molecule ensures one directional rhodamine cleavage which simplifies fluorescence studies. Rhodamine 110 is a laser grade fluorescent dye with excitation maxima at 496 nm and emission maxima at 522 nm.Peso molecular:851.3 g/molMyr-RLYRKRIWRSAGR-OH

Biotinylated aMp3 is a Mycobacterium avium subsp. Paratuberculosis (MAP) specific ligand. MAP can cause Johne disease (the wasting disease) in livestock. It is important therefore to detect the presence of MAP in animal milk and faeces.Biotinylated aMp3 can be used (along with aMptD peptides) to detect the viability of MAP cells in infected livestock through combined peptide-mediated magnetic separation phage display due to their high affinity for MAP. The addition of biotin to aMp3 asparagine residue, changes the orientation of aMp3 so that it can bind to the target bacteria with increased stability, thus achieving a high capture efficiency. A similar effect is observed on the addition of biotin to aMptD glycine residue.Peso molecular:1,642.8 g/molH-AYATEPHAK^-OH

Apolipoprotein A-I enables the efflux of fat molecules from within cells as high-density lipoprotein (HDL) particles for transport back into LDL particles or to the liver for excretion. HDLs are one of five major groups of lipoproteins.Increasing concentrations of HDL particles are strongly associated with decreasing accumulation of atherosclerosis within the walls of arteries. Apolipoprotein A-I is often used as a biomarker for prediction of cardiovascular diseases, such that low levels of APOA1 are associated with an increased risk of adverse events in patients with coronary artery disease. In such cases, APOA1 can be used as a biomarker to predict cardiovascular disease progression.Peso molecular:1,930.9 g/molTAT (48-57)

NanoLuc (Nluc) is an engineered luciferase protein which was developed from the luciferase of deep-sea shrimp (Oplophorus gracilirostris). This luciferase protein is considerably smaller than firefly or Renilla luciferase yet has higher luminescent intensity.In the NanoBiT assay system the NanoLuc luciferase protein has been separated into a large fragment, LgBiT, and a small fragment. HiBiT has a very similar amino acid sequence to the original small fragment and therefore has high specific affinity for the N-terminal large fragment, LgBiT. When these two fragments interact NanoLuc activity is restored. This system offers a novel alternative to conventional immunoblot analysis for the detection of protein expression when the HiBiT tag is added to the protein of interest and cell lysate is incubated with LgBiT. HiBiT peptide is capable of producing bright and quantitative luminescence through high affinity complementation with an 18 kDa subunit derived from NanoLuc (LgBiT).Forma y color:PowderPeso molecular:1,319.8 g/molH-FIPLIPIPER^-OH
