SAMPLE SUBMISSION AND PAYMENT

How to Submit Samples for Processing

    1. For Proteomics: Email David Hawke at dhawke@mdanderson.org to set an appointment to discuss the details of your experimental design.

        For Metabolomics: Email Phil Lorenzi at PLLorenzi@mdanderson.org to set an appointment to discuss the details of your experimental design.

    2. Go to mdanderson.ilabsolutions.com to register your online account. Once that is completed, you can begin to request services. For more detailed instructions on setting up your account, please Click Here

    3. Upon approval of your online service request, you will be notified via email to set an appointment for sample drop off. **Note: Samples will not be accepted without an appointment!

SERVICES WE PROVIDE:

Proteomics

Protein Identification

  •  High sensitivity (silver stain is OK), up to 100 proteins or more may be identifiable.
  •  Cost: $200/sample
  •  Turnaround Time: 5-10 working days

Molecular Weight Determination

  •  Check the MW of your peptide or molecule. Proteins may also be measured if enough clean protein is available  (larger proteins are less reliable)
  •  Cost: $50/sample
  •  Turnaround Time: 4-10 working days

Quantitative Protein Analysis

  • Using stable isotope methods, iTRAQ, etc.
  • Using non-isotopic methods.
    • Please Inquire
    • For SRM/MRM methods on our tandem quadrupole MS please inquire.

Posttranslational Modification Analysis

  •  Phosphorylation and acetylation. Please inquire for more detailed information and other analyses that can be performed. 
  •  Cost: $500/sample
  •  Turnaround Time: Will vary

HPLC-MS

  •  Size exclusion chemotography and simple LC-MS. Please inquire for more detailed information and other analyses that can be performed.
  •  Cost: $100/sample
  •  Turnaround Time: Will vary

Edman Degradation, Quantitative Metabolite Analysis & Large-Scale PhosphoProteomics

  •  Please Inquire

Do you need higher resolution than you see here or some other MS service?

  •  Please Inquire - Consultations for custom assays for other MS interests are also available. 

Metabolomics 

Please email or call for an appointment to discuss your project!

   

Silver Staining of Protein Gels

Recommended Silver Stain

Download Silver Stain Protocol (pdf).  Please ignore destain, we destain after cutting the bands

Reagents

Silver Solution

  • 0.1% AgNO3 in H2O: 0.1g AgNO3 dissolved in 100 ml H2O

Developing Solution

  • 3% Sodium carbonate (Na2CO3) in H2O
  • 50 µl formaldehyde/100 ml
  • Stir for 2 minutes

Procedure

All incubations are at room temperature, and carried out with gentle shaking on a shaking platform. All steps take place in a clean (acid washed) pyrex dish. 

Make up all solutions fresh, just before use.

  • Incubate 15 min in 50% methanol
  • Incubate 15 min in 32 µM DTT (8 µl 1M DTT /250 ml water) solution (freshly made)
  • Wash briefly (approximately 5 to 10 seconds) with H2O, twice
  • Wash with a little Silver Solution, pour away, then add the rest of the solution and incubate for 15 minutes
  • Wash briefly (approximately 5 to 10 seconds) with H2O, twice
  • Twice wash with a little Developing Solution, pour away, then add the rest of the solution and incubate until the bands are the desired intensity
  • Pour off most of the developing solution, sprinkle solid citric acid into the solution containing the gel and swirl. Continue slowly adding the citric acid until the fizzing ceases
  • Add a little H2O, and incubate 15 minutes
  • Incubate 3 X 15 minutes with 3 changes of H2O
  • Preferred: Bring the gel to our lab; we prefer to cut the bands here
