PeproTech Active cytokines FAQs

Quality controls:

1. Authenticity: by N-terminal sequence analysis, and, when possible, by SDS-PAGE, RP-HPLC, and Mass Spectrometry analyses versus standards

2. Purity: by SDS-PAGE and RP-HPLC analysis

3. Biological Activity: by the relevant in vitro or in vivo bioassay

4. Protein content: by UV spectroscopy, SDS-PAGE analysis and, when possible, by HPLC analysis versus the calibrated standard solution

5. Endotoxin contamination: by kinetic LAL method

6. Microbiological contamination: by membrane filtration method; protein solutions are sterile-filtered prior to vialing
