Custom research peptide; min purity 95%. For different specs please use the Peptide Quote ToolFórmula:C45H72N14O12Peso molecular:1,001.16 g/molNeurokinin A (Substance K)
Neurokinin A (NKA) is a member of the classical tachykinins family of peptides which also includes substance P and neurokinin B. These peptides are primarily found in the nervous system where they act as neurotransmitters and neuromodulators. They also play key roles in neuronal inflammation, and high levels of NKA have been linked to poor prognosis of some tumours.The tachykinin peptides are characterised by a common C-terminal sequence, Phe-X-Gly-Leu-Met-NH2, where X represents either an aromatic (Phe, Tyr) or a branched aliphatic (Val, Ile) amino acid.This C-terminal region is thought to be responsible for activating the receptor. The divergent N-terminal region is thought to play a role in determining the receptor subtype selectivity. NKA binds preferentially to the NK2 receptor.Peso molecular:1,132.6 g/molKHLF-[AMC]
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.Cor e Forma:PowderPeso molecular:700.4 g/molKisspeptin-10 (Human) / Metastin (Human, 45-54)

Bombesin/GRP receptor agonist derived from the pro-apoptotic protein BIM, which is a member of the BCL-2 family proteins and activates the BAX and BAK proteins to promote apoptosis.The process of apoptosis can be activated by the intrinsic or extrinsic pathways, the former is activated by stress stimuli such as DNA damage and nutrient deficiency, while the latter is induced through activation of the death receptors FAS and TRAIL.The BCL-2 family's transmembrane anchor at the C-terminus allows them to locate at the mitochondrial outer membrane and play a vital role in apoptosis.Within the mitochondria BIM is a member of the BH3 molecules alongside, BIM, PUMA and NOXA which can all be activated by the intrinsic pathway. These in turn can initiate the homo-oligomerisation of BAX and BAK which induce mitochondrial outer membrane permeabilisation (MOMP) and the release of cytochrome c into the cytosol. Here cytochrome c associates with APAF-1 and dATP, ultimately activating effector caspase3/7 and apoptosis.BIM can be activated by CHOP-mediated transcription and phosphatase 2A-mediated dephosphorylation during endoplasmic reticulum stress. However when BIM is phosphorylated it undergoes degradation by the proteasome.Peso molecular:1,068.6 g/molLCBiot-YGGFLRRIRPKLK-OH

C5a receptor 2 (C5aR2, or C5L2) is a seven transmembrane non-G-protein-signalling receptor which binds the complement activation peptide C5a ligand. The complement cascade is a highly sophisticated network of innate immune proteins that are activated in response to invading pathogens or tissue injury. C5aR2 regulates the release of certain cytokines and is involved in a number of inflammatory conditions. C5aR2 can recruit and form a complex with β-arrestins, which can modulate ERK1/2 signalling in macrophages and neutrophils. C5aR2 has both pro- and anti-inflammatory actions. P32 is a functionally selective C5aR2 ligand which is able to recruit β-arrestin 2 with high efficacy, inhibit C5a-induced ERK1/2 activation and can selectively inhibit LPS-induced IL-6 release from human monocyte-derived macrophages (HMDMs). Functionally selective ligands for C5aR2 such as this are novel tools that can selectively modulate C5a activity and are therefore valuable tools in investigating C5aR2 function.Peso molecular:1,118.5 g/molUbenimex (Bestatin) HCl Salt
CAS:Ubenimex is a peptide-based inhibitor of aminopeptidase enzymes that act on the N-terminus of amino acid chains. It is also an inhibitor of Leucine aminopeptidase 3 (LAP3) and a potent irreversible inhibitor of Leukotriene A4 (LTA4) hydrolase. It is used in the treatment of non-alcoholic steatohepatitis. Ubenimex binds to the active site of aminopeptidases and inhibits their activity, thus preventing degradation of peptides. Ubenimex has been shown to inhibit aminopeptidase A and B, but not C or D. As a result, it prevents cleavage of the N-terminal amino acids from proteins, which may be involved in inflammatory processes. Furthermore Bestatin has been shown to exhibit antibacterial properties against P. gingivalis and F. nucleatum and is available in the salt form: Hydrochloride.Pureza:Min. 98%Peso molecular:344.84 g/molShepherdin (79 - 87)
Shepherdin is an antagonist of the interaction between the apoptosis protein, survivin, and the molecular chaperone, heat shock protein 90 (Hsp90). The sequence of shepherdin corresponds to the site where Hsp90 binds to survivin. Shepherdin therefore has high affinity for Hsp90 and thus disrupts survivin binding and acts as an inhibitor of Hsp90 ATPase function by competing with ATP.The survivin-Hsp90 complex is a regulator of cell proliferation and cell viability in cancer tissue. Shepherdin has anti-cancer properties and can significantly suppress the growth of lung cancer cell lines and acute myeloid leukaemia (AML) by inducing apoptosis.Cor e Forma:PowderPeso molecular:948.4 g/molPASD1 167-175 (HLA-A*02:01)

ARF peptide
ARF peptide, is the alternative frame (ARF) tumour suppressor protein which is expressed on the occurrence of oncogenic stimuli. It functions to prevent abnormal cell proliferation through inhibiting the p53 ubiquitin ligase protein Mdm2 from degrading p53. This results in the increased stability of the p53 tumour suppressor causing G1 cell cycle arrest. Additionally mouse ARF proteins can localise E2F1 and c-Myc transcriptions factors to the nucleolus therefore they are no longer able to activate S-phase promoting target gene. Again this results in cell cycle arrest, ultimately preventing tumour cell growth. It is evident that if the expression of the ARF peptide is inhibited tumour formation is more likely to occur.Cor e Forma:PowderPeso molecular:1,867.1 g/molPal-KVK-OH
Peptide Pal-KVK-OH is a Research Peptide with significant interest within the field academic and medical research. This peptide is available for purchase at Cymit Quimica in multiple sizes and with a specification of your choice.N-formylated PSMalpha2
Pathogenic Staphylococcus aureus strains produce N-formylmethionyl containing peptides. Peptides starting with an N-formylated methionyl group constitute a unique hallmark of bacterial as well as mitochondrial metabolism, and professional phagocytes of our innate immune system recognise this microbial/mitochondrial pattern as a danger signal that guides innate immune cells.All PSMα peptides have the same basic functions and promote virulence through effects on discrete neutrophil functions (i.e. chemotaxis) and by being cytotoxic at higher concentrations. PSMα2 and PSMα3 can both bind to FPR2 and trigger superoxide release in neutrophils at low nanomolar concentrations. In addition, at high nanomolar concentrations they display cytotoxicity selectively on apoptotic neutrophil membranes and this occurs in an FPR2 independent manner.Cor e Forma:PowderPeso molecular:2,304.4 g/molH-AVQVHQDTLR^-OH
