MDACC RPPA-Functional Proteomics

Overview of Services

 Reverse phase protein array (RPPA) is a high-throughput antibody-based technique developed for Functional Proteomics studies to evaluate protein activities in signaling networks. The RPPA Core provides services to perform such an assay for your studies.


What We Do

  • Perform reverse phase protein arrays on the samples received from customers.
  • Perform custom antibody validation using a reverse phase protein array.
  • Provide standard operating procedures needed for the extraction of proteins from cell lines and tumor tissue for use in the reverse phase protein array studies.
  • Perform primary data analysis using custom software to determine signal intensity, curve construction, and relative protein expression and modification.
  • Perform protein extraction from tumor tissue or cell pellets, upon request (with additional charge), for use in the reverse phase protein array studies (see pricing below).
  • Provide updated lists of antibodies for reverse phase protein array studies:
    • Standard Panel containing ≥290 antibodies (for human samples and mouse cell lines) and ≥225 antibodies (for mouse tissue samples)
  • Provide robust information using a panel of antibodies.
  • Provide a turnaround time within 8-10 weeks of sample submission. However, occasionally, based on workload or equipment failure, analysis may take up to 12 weeks.


Our Staff Director is Yiling Lu, M.D., who has worked on the RPPA platform since 2004 and has directed the Reverse Phase Protein Array - Functional Proteomics Core Facility since 2008.

Name Description Price
Additional Antibody Charge and Validation--New to Core (Antibody Supplied by Customer)

For use if you would like to supply and include an antibody that is not on our Standard Antibody List and that we have not previously validated and used at our RPPA Core. 


*This includes validating your antibody using our standard RPPA validation process.  We will report to you whether or not your antibody passes our validation criteria and will apply your antibody to your samples upon validation.


Additional Antibody Charge--Previously Validated (Antibody Supplied by Customer)

For use if you would like to supply and include an antibody that is not on our current Standard Antibody List and we have previously validated and used at our RPPA Core.

Additional Data Sets with Heatmaps

Price is per data set, which includes a report containing raw data, normalized data, and centered-median data and a pair of heatmaps (1 supervised and 1 unsupervised).

Protein Extraction from tissue or cell pellets

Price is per sample.
