Choosing whatdegree of purity is important in peptide research and it’s not always the case that the higher thepurity is, the better. Generally for the same sequence and the same amount of peptide,different purities decide different prices. Our company can provide differentlevels of purity for customers to choose, from the crude to> 98% purity. Accordingto customer needs we can provide a ultra purity of> 98%. Various degrees ofpurity and range of application are as follows: > 80% for immunization experimentsand insensitive screening assays> 90% for SAR research and biologicaldetection > 95% for NMR, crystal structure research and biological detection.
