Vascular endothelial growth factor (VEGF) is a potent angiogenic factor and was first described as an essential growth factor for vascular endothelial cells. VEGF is up-regulated in many tumors and its contribution to tumor angiogenesis is well defined.

Beta Amyloid peptides, also called Amyloid beta peptides (Abeta peptides) are the main component of amyloid peptide plaques in the brain of patients with Alzheimer's disease. sb-PEPTIDE provides a broad range of chemically synthesized amyloid beta peptides for Alzheimer's disease research. We supply Abeta peptides of different lengths and point-mutated versions. Do not hesitate to contact us for any information. 

Angiotensin-converting enzyme 2 (ACE2) is an enzyme involved in the cardiovascular system by decreasing arterial pressure by catalyzing the conversion of angiotensin II to angiotensin (1-7). Angiotensin II is a vasoconstrictor and angiotensin (1-7) is a vasodilatator. This effect makes ACE2 a therapeutic target for cardiovascular disease. Otherwise, ACE2 also corresponds to a receptor allowing the coronavirus (SARS-CoV-2) to enter the host cell. sb-PEPTIDE provides ACE2 as an overlaped library with biotinylated peptides of 15 amino acids with an overlap of 11 amino acids. 1 peptide per well.

Biotin-Ova (323-339) is the N-ter biotinylated version of Ova (323-339). Biotin-Ova (323-339) can be used in the analysis of antigen-specific T cells. Ovalbumin protein: Ova (323-339) is an epitope of interest of the egg white albumen, which is widely used in allergy research. Ovalbumin is a glycoprotein that is sufficiently large and complex to be mildly immunogenic. Indeed, it has been demonstrated that Ovalbumin contains B-cell epitopes which are recognized by specific IgE antibodies and CD4 T cell epitopes restricted by the MHC I-Ad molecule in mice and by HLA-D molecule in human. Applications of Ova (323-339): Ova (323-339) allows to study bindings of class II MHC-peptide and T-cell activation in PBMCs by ELISPOT assays. In fact, this method quantifies peptide epitope specificity and IFN-γ releasing effector cells. It has been shown that Ova (323-339) was responsible for 25-35% of T-cell response of isolated BALB/c mouse. An investigation has demonstrated that Ova and Ova (323-33

[Pyr1]apelin-13 (human) (CAS: 217082-60-5) Apelin GPCR-Receptor The Apelin receptor, also known as APJ, APLNR, and AGTRL1, is a member of the class A family of G protein-coupled receptors (GPCRs). It has been identified in various species, including mouse, rat, cow, rhesus macaque, Xenopus laevis, and Danio rerio, and it shares structural similarities with the angiotensin II type l receptor (AT1). However, despite a 54% homology in transmembrane regions with AT1, it does not bind angiotensin II. Initially designated as an "orphan" GPCR, due to the absence of a known ligand, O'Dowd & al. named it APJ in 19935. Comprising 380 amino acid residues, APJ features the characteristic 7-transmembrane domain structure, typical of a class A GPCR. Nowadays, it is known that APLNR depicts physiological roles, including regulation of cardiovascular function, fluid homeostasis, the adipoinsular axis, gastrointestinal and immunomodulatory functions.
