Mambalgin-1
Mambalgin-1 is a natural product with an unknown pharmacophore. It has been shown to inhibit cancer cells in vitro and in vivo by suppressing the activation of suppressor genes, which are genes that regulate cell proliferation. Mambalgin-1 may also be effective against other diseases such as Parkinson's disease, Alzheimer's disease, and Huntington's disease. Mambalgin-1 is synthesized from a solid-phase synthesis of a cyclic peptide that contains two acidic amino acids. This synthetic compound binds to the extracellular region of synaptic vesicles and inhibits the release of neurotransmitters. The mechanism of action is not yet known, but it is thought that this compound may inhibit calcium channels or potassium channels in the presynaptic membrane.Fórmula:C272H429N85O84S10Pureza:Min. 95%Peso molecular:6,554.61 g/molLeptin (93 - 105) Human
Leptin is a member of the adipocytokines or adipokines group of cytokines primarily produced in adipose tissue. Leptin is a hormone involved in multiple endocrine functions, bone metabolism and thermoregulation, and a cytokine promoting inflammatory responses. There are elevated levels of leptin found in people with obesity. This contributes to the state of low-grade inflammation that makes those individuals more likely to develop cardiovascular diseases, type II diabetes, degenerative disease and autoimmune disease. Reduced levels of leptin, found in malnourished individuals, have been linked to an increased risk of infection and reduced cell-mediated immunity.Leptin binds to leptin receptors (ObRs), of which there are at least six isoforms (ObRa, ObRb, ObRc, ObRd, ObRe, and ObRf). Leptin-related analogs such as (93-105) fragment can mimic the interaction and activation of the ObR to improve their anti-obesity effects. Peptide vectors with a linker to a leptin fragment were patented as new leptin agonists with an improved permeability through the blood-brain barrier. Administration of leptin or leptin (93-105) to rats was shown to raise the blood levels of aldosterone and corticosterone. The use of the (93-105) fragment has allowed a better understanding of full-length leptin and its function in its various roles.Forma y color:PowderPeso molecular:1,526.8 g/molGLP-1 (7-36) [Cys(Sulfocyanine5)]
The native form of GLP-1 in humans is the GLP-1 (7-36) amide. GLP-1 (7-36) amide is highly unstable (half-life <-2 minutes) due to proteolytic degradation by the serine protease, dipeptidyl peptidase-IV (DPP-IV). DPP-IV cleaves the N-terminal histidine and alanine residues from GLP-1 to generate two equipotent forms: GLP-1 (9-37) and GLP-1 (9-36) amide. This degradation mitigates against the therapeutic use of GLP-1 itself, therefore DPP-IV-resistant peptide analogues have been developed and licensed for clinical use.Contains a sulfo-Cyanine5 fluorescent dye, an analogy of Cy5® and one of the most popular fluorophores. Sulfo-Cyanine5 is a red emitting fluorescent dye which is highly hydrophilic and water-soluble. Compatible with various equipment such as plate readers, microscopes, and imagers.Forma y color:PowderPeso molecular:4,162.9 g/molH-2Kb Mouse L protein LEYDFNKL

The coronavirus (CoV) nucleoprotein is the major component of CoV structural proteins. Also known as the nucleocapsid protein, it is an abundant RNA-binding protein critical for viral genome packaging. These factors make nucleoprotein a good target for developing new antiviral drugs. In addition, the identification of epitopes within the nucleoprotein sequence can help design more effective SARS-CoV-2 vaccines.Models have predicted epitopes exhibiting antigenicity, stability and interactions with MHC class-I and class-II molecules. Nucleoprotein (266-280) is an epitope candidate with various HLA restrictions. This epitope can be used to better vaccine design for more durable CD4+ and CD8+ T cell responses for long-lasting immunity.Peso molecular:1,692.9 g/molSIVmac239 - 87

GIP (1-30) Human amide is derived from the Gastric inhibitory peptide (GIP). Gastric inhibitory polypeptide (GIP) is an inhibiting hormone of the secretin family of hormones. While GIP is a weak inhibitor of gastric acid secretion, its main role is to stimulate insulin secretion - in a glucose-dependent mechanism. Therefore, GIP is referred to as a glucose-dependent insulinotropic peptide.GIP is derived from a 153-amino acid pro-protein encoded by the GIP gene. It is synthesised by K cells, which are found in the mucosa of the duodenum and the jejunum of the gastrointestinal tract. GIP receptors are seven-transmembrane proteins found on β-cells in the pancreas. These β-cells are those that are able to simultaneously detect glucose and release insulin as a result to GIP binding.The clinical relevance of GIP is related to type 2 diabetes mellitus (T2DM)- studies have found that T2DM diabetics are unresponsive to GIP and have lower levels of GIP secretion after a meal when compared to non-diabetics. In research involving knockout mice, it was found that absence of the GIP receptors correlates with resistance to obesity.

Amino acids 1-6 of amyloid β peptide (Aβ). This fragment represents an immunogenic portion of Aβ which has been used as the basis for potential immunotherapies for Alzheimer's disease. 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.Contains a GGC linker, the thiol on the Cysteine can be used for conjugation to dyes and other molecules.Forma y color:PowderPeso molecular:990.4 g/molLeuprolide Acetate
Leuprolide acetate is a synthetic peptide analogue of naturally occurring gonadotropin releasing hormone (GnRH also known as luteinising hormone-releasing hormone, LHRH). Leuprolide Acetate has a longer half-life and a higher affinity to the pituitary GnRH-receptor than physiological GnRH due to the presence of a D-amino acid. Leuprolide acts as a super-agonist of the pituitary gonadotropin-releasing hormone (GnRH) receptor in the hypothalamo-pituitary-gonadal axis and disrupts the maintenance of the normal hypothalamo-pituitary-gonadal axis and desensitizes the GnRH receptor. This results in lower levels of testosterone in the blood. Leuprolide is used to treat prostate cancer, endometriosis, fibroids and precocious puberty. Peptide is for research purposes only, strictly not for human use.Peso molecular:1,208.6 g/molClick Tat (47-59)
Tat (47-59) is a cell penetrating cationic peptide derived from the N-terminus of the Tat protein, which is a trans-activator of the transcription protein present in the human immunodeficiency virus (HIV). Specifically, TAT (47-57) is located within the arginine-rich basic domain of the TAT peptide. TAT has three domains which function to aid HIV through transactivation, DNA binding and nuclear transport. As a cell penetrating peptide (CPP) TAT aids in the cellular uptake of molecules and hence serves a valuable purpose in transduction methods. This property has been demonstrated through its ability of allowing toxins such as the neurotoxin Botulinum neurotoxin Type A, produced by the Clostridium botulinum type A bacteria to penetrate the skin barrier non-invasively.Tat (47-59) is provided here with a N-terminal alkyne attachment. Two of the most regularly encountered functional groups for click chemistry are azides and alkynes, and the azide-alkyne cycloaddition has become the most popular click reaction. The use of click chemistry with alkyne-Tat (47-59) allows a wide variety of applications particularly for conjugation, modification, and peptide design.Forma y color:PowderPeso molecular:1,797.1 g/molH-MPRHSRAKRAPRPSAC-NH2
