Is it compliant to use different primary antibodies, some monoclonal and some polyclonal, for immunofluorescence staining and WB bands?
The choice between monoclonal and polyclonal antibodies is not an issue, but rather a decision based on experimental design. It is reasonable to select different types of antibodies depending on the experimental objectives and context. The key is to ensure that the antibodies you use are validated and can specifically detect the target protein under your experimental conditions.
Considerations for using monoclonal or polyclonal antibodies in experiments:
1. If the protein you are studying has different isoforms or post-translational modifications and you want to detect these different forms, using polyclonal antibodies might be more appropriate.
2. If you need to detect a specific protein with high specificity, then using monoclonal antibodies might be better.
3. In some cases, using a combination of both can be a good choice. You can obtain an overall detection result with polyclonal antibodies and then confirm specific protein forms with monoclonal antibodies.
