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
