Notes: 1. MALDI-TOF (PMF) and MALDI-TOF/TOF (PMF + MS/MS) services include protein digestion, desalting and peptide concentration using a commercial C18 micro column, MS data acquisition, Mascot database searching and a standard report. Prices for samples that result in one or more database matches are the same as the price for samples where a match is not found. 2. 1D nanoLC ESI MS/MS services include protein digestion, reversed phase nanoLC and MS data acquisition, Mascot database searching and a standard report. Prices for samples that result in one or more database matches are the same as the price for samples where a match is not found. 3. De Novo peptide sequencing is undertaken an additional data analysis service based on the data acquired from MALDI-TOF/TOF or ESI MS/MS when there is no matches from automated database searches. 4. Desalting with porous R2 beads micro column is a service using self packed porous R2 micro column to desalt and concentrate proteins and peptides. This is recommended if salt needs to be removed from solution for intact protein mass analysis. It is also recommended for 2D gel faint spot MALDI MS analysis. 5. Reduction and alkylation of samples prior to shipping is recommended. Should APAF need to perform this work, the cost will be passed on to the customer. Sample reduction and alkylation is recommended when the following services are requested: MALDI-TOF (PMF), MALDI-TOF/TOF (PMF + MS/MS) and LC ESI MS/MS for protein identification. Note: Spots submitted from 2-D gels are usually alkylated during the process of 2-DE and therefore do not require any subsequent alkylation steps. 6. Special sample treatment includes other services such as extracting proteins from samples, depleting high abundant proteins, 1D SDS or 2D gel electrophoresis for protein separation, HPLC for protein separation and image analysis. 7. Please contact APAF to discuss the scope of the services required and associated fees. 8. Other amino acids available upon request (e.g. hydroxyproline, taurine). 9. A fee based upon set up costs and per residue sequenced is charged. Approximately 10 residues are normally sequenced to get an identification. |
