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.

gp100 (280-288) A288V HLA-A*0201 antigen peptide – YLEPGPVTV SB-PEPTIDE offers gp100 (280-288) A288V variant peptide – YLEPGPVTV for its promising use in immunotherapy. gp100 protein: potent melanoma-specific antigen gp100 (Uniprot: P40967) 661 amino acids long type I transmembrane glycoprotein, also known as premelanosome protein (PMEL) for the gene encoding it, is primarily known for its crucial role in melanosome morphogenesis and pigmentation. Indeed, it orchestrates the maturation of these organelles, that are responsible for melanin synthesis, storage, and transport. More than its implication in melanosome maturation, melanogenesis, biogenesis, and melanin polymerization, gp100 has gained significant attention and recognition as tumor-associated antigen (TAA). Hance, its dynamic and multifaceted nature piqued the interest of researchers and immunobiologists to explore PMEL’s potential in shaping the future of cancer treatment. gp100 280-288 immunogenic epitope – YL

Biotin-PEG-Thiol (MW 2000) is a pegylated compound with high affinity and specificity for streptavidin or antibiotin, capable of modifying biomolecules, proteins, peptides, and small molecular materials. It is commonly used in agent release research and the development of novel nanomaterials [1].
