Can IP Extraction Proteins Be Stored at -80°C Like WB Proteins
Yes, protein samples for immunoprecipitation (IP) can usually be stored at -80°C, just like protein samples for Western blot (WB). The key is to avoid repeated freeze-thaw cycles during storage, as this may cause protein degradation or inactivation. When using the sample, it should be thawed completely and used in one go.
