Macromolecular Synthesis

The Macromolecular Synthesis Core at Penn State College of Medicine was established in 1987, with primary grant support from the National Science Foundation and College of Medicine funds. The facility subsequently received grant support from the NIH and the Commonwealth of Pennsylvania via the Ben Franklin Partnership, and matching funds from the College of Medicine.

Services offered include:

  • Peptide synthesis
  • Oligonucleotide synthesis
  • Image analysis and gel band quantitation (for which instrumentation purchased with Tobacco Settlement Funds)

Instrumentation and Services

Peptide Synthesis Expand answer

A standard synthesis delivers between 50 and 80 mg of peptide. Custom syntheses are also possible (e.g., phosphopeptides, biotinylated peptides), with an additional cost being determined by the reagents used.

Oligosynthesis Expand answer

The Polygen synthesizer is used to generate oligonucleotides. The cost depends on the scale of the synthesis needed. Many users choose to have their oligonucleotides purified, which can be done with Nensorb columns. Custom syntheses such as modified bases and phosphorothioate chemistries are also available, as are larger-scale syntheses.

Procedures, Protocols and Forms

Peptide Synthesis Procedures Expand answer

Full-scale synthesis (approx. 0.2 mmol yield) or half-scale synthesis (approx. 0.1 mmol yield) is available, with fees that cover the cost of the reagents.

Peptides will be prepared as a lyophilized powder cleaved from the resin in the presence of appropriate side group preservatives, extensively washed and extracted following cleavage with various solvents to remove the majority of the impurities (preservatives and byproducts of the cleavage procedure.

Molecular weight verification and synthesis purity is available using mass spectrometry for an additional fee.

Oligosynthesis Procedures Expand answer

The core can provide 0.05 µM scale synthesis, 0.25 µM scale synthesis or 1.0µM scale synthesis.

Two different levels of Nensorb purification are available: one for oligos synthesized at 0.05 µM or 0.2 µM scale synthesis, and another larger column used for oligos synthesized at 1.0µM scale synthesis.

Pickup procedure: After synthesis, oligos may be picked up from the top shelf of the freezer in room C1732, with the data sheets attached to the side of the freezer. An approximate yield of micrograms of oligo will be included on the data sheet, but because this is calculated based on the A260 while the oligo is still in methanol before lyophilization, it is only approximate. Investigators must requantitate the yield and concentration of each oligo after it is resuspended in water or TE buffer in order to have an accurate measure of yield/concentration.
