In order to save your scientific research costs and meet your scientific research requirements, Qiangyao Biological 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.
