Preparing Your Samples for Submission
- Design your experiment based on biological question. If your data needs to be analyzed statistically, please discuss your experiment design with your bioinformatics group prior to setting up your experiment.
- Prepare your RPPA samples (protein lysates) from cultured cells or tissue samples based on the procedures provided on the Antibody Lists and Protocols page.
- Adjust the protein concentration to approximately 1.5 µg/µl (no less than 0.75 µg/µl).
- Denature protein by 4XSDS sample buffer. (Final Concentration after denaturation should be ~1 ug/ul)
- A minimum 40 µl of protein lysate is required for RPPA analysis.
Current Sample Types Accepted by the RPPA Core Include:
- Cultured cells
- Mouse xenografts
- Frozen human tissue
We DO NOT accept FFPE samples for RPPA Processing, due to the lack of quality and analyzable protein present within this sample type.
Biological replicates are encouraged.
