PeptaNova

PeptaNova offers EIA and ELISA kits from Yanaihara Institute Inc. for the quantitative measurement of selected peptides, hormones, and biologically relevant biomarkers in research samples. Yanaihara Institute develops assay kits and antibodies to support biological, medical, and basic research, with kit categories covering obesity and diabetes-related research, stress, tumor and aging-related research, environmental hormone research, and brain damage / brain hemorrhage-related research. 

The portfolio includes chromogenic, fluorescent, and fluorescence-quenching enzyme substrates for biochemical and enzymology research. Common substrate formats include pNA, AMC / MCA, AFC, and FRET-based substrates, enabling absorbance- or fluorescence-based detection of enzymatic activity.

These substrates support research involving aminopeptidases, angiotensin I converting enzyme, caspases, cathepsins and other thiol proteases, chymotrypsin, coagulation factors, collagenase, elastase, trypsin-like proteases, protein kinases, and the ubiquitin-proteasome system.

They are useful for enzyme kinetics, inhibitor screening, substrate specificity studies, protease activity assays, and functional enzyme analysis.

The portfolio includes well-defined, highly purified oligopeptides and polypeptides for biological and life science research. Products include short peptide sequences, cyclic diketopiperazines, glutathione, collagen-related repeat peptides such as Pro-Pro-Gly and Pro-Hyp-Gly, as well as poly-amino acids including poly-L-glutamic acid and poly-L-lysine salts.

These materials are useful as reference compounds, biochemical research reagents, and model peptides for studying peptide structure, sequence-dependent properties, polymeric amino acid systems, and related research applications. Product-specific documentation may include purity, molecular weight, storage conditions, SDS, and data sheets.

The portfolio includes peptide antisera and monoclonal antibodies for antibody-based peptide and protein research. Applications include immunohistochemistry, Western blot, ELISA, immunoprecipitation, RIA, and other non-isotopic immunoassay formats, depending on the individual product.

Peptide antisera include undiluted polyclonal antibodies with product-specific information such as host animal, immunogen, specificity, and suggested application conditions. Monoclonal antibodies include target, clone, antigen origin, specificity, cross-reactivity, Ig class, purification, concentration, formulation, and application-specific working conditions where available.

These reagents are suitable for target detection, peptide-related biomarker studies, immunoassay development, and tissue or protein analysis in research settings.

This category includes protected amino acid derivatives and specialized peptide building blocks for reliable peptide synthesis. The portfolio covers Boc-D-amino acid derivatives, Fmoc-D-amino acid derivatives, Fmoc-L-amino acid derivatives, and selected functional building blocks for the preparation of modified and sequence-defined peptides.

These reagents are used in solid-phase peptide synthesis, protected amino acid chemistry, regioselective disulfide formation, glycopeptide synthesis, and the development of modified peptide structures. Available products include protected D- and L-amino acids, Fmoc-protected specialty residues, Dawson linker-related building blocks, fluorescent and labeled peptide tools, and glycosylated Ser / Thr derivatives.

Suitable for peptide synthesis, method development, structural peptide research, and biochemical research applications.
