We offer an unparalleled portfolio of natural and unnatural amino acids, resins, and coupling reagents of unrivaled quality for peptide synthesis, including the entire portfolio of over 1,000 Novabiochem® products. Combining this extensive offering with the latest innovative products such as the phophoroserine building block, Fmoc-Ser(PO(NHiPr)2)-OH), Trp-BODIPY fluorescent probe, CITC coupling reagent, and the Pinc cyclization reagent we’ll make your breakthroughs feel closer than ever. Many products are supported by detailed protocols, application examples, and practical advice. Moreover, the famous Novabiochem application notes are now available online!
For years, Novabiochem® peptide synthesis reagents have set the gold standard for quality and reliability. The quality of reagents is critical to the scientific credibility of results obtained with synthetic peptides. Small, almost trivial, differences in purity of the starting reagents can greatly affect the microheterogeneity of the product peptide. For example, building blocks with only 99.5% optical purity can theoretically only produce 78% of the target 50mer, whereas building blocks with 99.8% optical purity rise to 90%. The purified products from both syntheses can look homogeneous by HPLC, however the peptide obtained using the 99.5% optically pure building blocks will only contain at maximum 78% of the target: the diastereomeric by-products will be hiding under the product peak as they are inseparable and are of course undetectable by MS.
It is for this reason we strive to make our 20 standard Fmoc-amino acids amongst the highest quality available on the market. Most importantly, we analyze for known microimpurities, which could produce inseparable and undetectable impurities in the final peptide product:
With the capability to offer large batches, we support your growth every step of the way, from R&D to scaled-up production across the globe. Get the exact quality and quantity you need for:
Aroma chemicals enhance the flavor or fragrance in a wide range of consumer products. Our certified food-grade, IFRA (International Fragrance Association), natural, kosher, and halal ingredients undergo scientific analysis and dedicated testing to provide safe and high-quality aroma chemicals for product formulation and development. A collaborative approach towards qualified vendors and compliance with internationally recognized regulatory requirements helps you meet the requirements of your customer.
ISOTEC® Stable Isotopes are stable isotope compounds, ranging from gases to complex molecules. These compounds are useful for tracer studies in proteomics and metabolomics, agents for MRI / MRS, and in a wide range of other biomedical applications.
Both tracer and flux studies benefit from stable isotope label assistance. Metabolic pathways can be studied by tracking naturally-occurring and disease-indicated metabolites. Additionally, the effects of exogeneous substances or perturbations on the metabolome can be elucidated with the use of our stable isotope-labeled internal standards coupled with mass spectroscopy determination.
