In order to save your scientific research costs and meet your scientific research requirements, ChinaPeptides(QYAOBIO) can provide you with different purity of polypeptides.
Peptides with purity greater than 70% are usually used for the preparation and detection of antibodies, and peptides with purity greater than 85% are usually used for the study of enzyme and biological activities. Peptides with purity greater than 95% can meet the requirements of quantitative analysis very well. We can provide grams of peptides with purity greater than 98% for use as apis. All the peptides synthesized by us have been tested by HPLC and MS, and the test report will be sent to you together with the peptides.
|Recommended Purity||Application Direction|
|Purity of immune grade polypeptide >70%||ELISA assay, location of epitopes, preparation of antigens and purification of polyclonal antibodies|
|Biochemical grade peptide purity >85%||In vitro and in vivo identification, cell attachment study, phosphorylation study, qualitative enzyme substrate study, enzyme protease antagonism experiment by Western blotting method|
|High purity polypeptide purity >95%||In vitro identification, in vitro identification, generation standard curve, NMR study, antigen determination cluster location
Quantitative proteolytic studies, quantitative phosphorylation studies, protease resistance and competition experiments, quantitative receptor ligand interaction studies
|Purity of medicinal grade polypeptide >98%||Pharmaceutical peptides, clinical trials, structure-activity relationship studies, cosmetic peptides|
We will send you the peptides together with the test report (HPLC, MS). Each peptide has passed our strict quality testing.
