Peptidi
I peptidi sono catene corte di amminoacidi legate da legami peptidici, che svolgono ruoli chiave come molecole biologiche importanti nei processi cellulari. Funzionano come ormoni, neurotrasmettitori e molecole di segnalazione, e sono ampiamente utilizzati in applicazioni terapeutiche e diagnostiche. I peptidi sono anche cruciali nella ricerca per lo studio delle interazioni proteiche, delle attività enzimatiche e dei percorsi di segnalazione cellulare. Presso CymitQuimica, offriamo una vasta selezione di peptidi di alta qualità per supportare le vostre esigenze di ricerca e sviluppo in biotecnologia e farmacologia.

PD-1 (24-38)
PD-1 (24-38) peptide is derived from the programmed cell death-1 (PD-1) which interacts with its ligand, PD-L1 to regulate immune homeostasis. PD-1 and its ligand PD-L1 are critical in regulating T cell activation, tolerance and immuno-pathology. PD-1 is an immune checkpoint and guards against autoimmunity through two mechanisms. First, it promotes apoptosis of antigen-specific T-cells in lymph nodes. Second, it reduces apoptosis in regulatory T cells.Several types of cancer cells overexpress PD-L1 in order to escape from the PD-1/PD-L1 immuno-surveillance mechanism. Consequently PD-1 inhibitors and PD-L1 inhibitors could be used as a therapeutic in the treatment of cancers.Colore e forma:PowderPeso molecolare:1,773.8 g/molH-Asp(OtBu)-2-ClTrt-Resin (100-200 mesh) 1% DVB

EBV BZLF1 (40-48) (HLA-E) is an immunodominant CEF control peptide that is derived from the Epstein-Barr virus (EBV). EBV targets B cells, which can cause lytic infection and the consequent death of these cells. Natural killer (NK) cells, invariant (iNKT) cells, CD4T cells and CD8 T cells are essential to control the action of EBV-infected cells. EBV BZLF1 (40-48) (HLA-E) is defined as a CEF control peptide due to its antigenic properties. Clinically, these peptides are suitable epitopes for CD8+ T cells and can be used to stimulate the release of IFNg. HLA-E refers to the cell HLA type that this peptide acts on.The BZLF1 protein mediates the transition from the latent stage to the lytic stage of the virus's infection. The lytic stage of the γ herpesvirus has been found to be associated with human carcinogenesis and BZLF1's ability to activate p53 may allow it to induce DNA damage. Structurally it is similar to the leucine zipper family of transcriptional factors.Peso molecolare:926.5 g/molLCBiot-SPDVDLGDISGINAS-OH

Albumin (50-62) Bovine is derived from the globular protein Albumin and is found in the blood plasma of humans (known as Human Serum Albumin, HSA) where it serves to maintain plasma pressure and nutritional balance. Another role it carries out is the transportation of bound molecules through the blood. Bovine serum albumin (BSA), composed of 583 amino acids, is very similar to HSA thus allowing BSA to be used as a successful model and a standard protein in laboratory experiments.Although BSA and HAS share homology in their three domains, I, II and III, BSA contains 2 tryptophan whereas HAS only contains 1 tryptophan residue. In agriculture the presence of the albumin protein has been used to assess the health of cows to ensure that a suitable quality of milk and meat are produced. Moreover it is important to detect bovine albumin in food and pharmaceutical products due to it being an allergenic protein.In agriculture the presence of the albumin protein has been used to assess the health of cows to ensure that a suitable quality of milk and meat are produced.

Recombinant human interferon-β (IFNB) is a therapeutic for certain stages of multiple sclerosis (MS). However, a significant portion of patients develop neutralising antibodies within 2 years and prevent clinical efficacy of the treatment, this was correlated to a specific rise in IgG. Sequencing of IFNB1 revealed a CD4+ T cell epitope residues (118-132) that contains critical T cell activation residues. The identification of this sequences can now allow it to be manipulated to hopefully provide new interferon treatments that reduces the capacity for induction of neutralising antibodies in MS patients. The IFNB1 (118-132) epitope can be used for immunological investigations such as T cell activation, antibody recognition via immunoassays and immunohistochemistry. This may provide further insights into certain haplotypes correlating to IFNB responses in MS treatment.Peso molecolare:1,906.23 g/molAc-AGGKAGKDSGKAKAKAVSR-OH

CAS:Phytosulfokine (PSK) was introduced in 1996 by Matsubayashi and Sakagami of Nagoya University. It is the world's first peptide phytohormone to be isolated from asparagus culture medium. Tyr undergoes post-translational sulfation modification, which is essential for bioactivity. As an example of oxidative peptides showing bioactivity, in animals, CCK-octapeptide (26-33) (sulfated form), PCK-4100-V, CCK-33 (Human), PCK-4201-S and CCK-33 (Porcine), PCK-4176-S are known, but they were first found in plants. The functions of phytosulfokine are i) plant cell proliferation and differentiation activity acting at nanomolar concentrations ii) chlorophyll synthesis-promoting activityiii) formation of adventitious roots and buds iv) adventitious embryogenesisv) involvement in disease resistance The active expression of these PSKs is accompanied by membrane-bound LRR receptors, which are PSK receptors. Leucine-rich repeat receptor-like kinase is involved.
