Samples should be labeled with your initials and a serial listing. For example, assume your name is Mary Lynch, and you are submitting four samples. Your samples should be labeled ML1 through ML4. The next time you submit samples for sequence analysis, begin with ML5 and continue in this fashion. All tubes must be labeled individually.
Samples collected by 9:30 am will be posted by 10:00 am the next day.
Samples can be dropped-off Monday through Friday, between 9:00 am and 5:00 pm in BST L5, Rm 151. Also we have two drop boxes located at Life Sciences Building 2nd floor Room 253 and at CMM (Center for Molecular Medicine) 4th floor Room 450. The drop off time at these two locations is between 9:00 am and 5:00 pm.
The recommended quantities of Template DNA are shown in the table below:
Samples should be submitted in 0.2ml strip tubes. In the 0.2ml tube combine the following: sample DNA (please refer to the above table for the amount of DNA to use), 3.2pmol primer/sample, PCR water to 8µl. The total volume of each sample should equal 8µl.
Yes, unless the fault is ours; e.g. computer collection glitch or other hardware problem. Several control samples are processed on every run and the results of these standards are posted with your results in the bins outside the lab for you to consult. If you would like to obtain a copy of our control results, please ask one of the faculty members and we would be happy to provide you with a copy. In the event of a facility problem, we will re-run your sample(s) free of charge.
Leading causes of poor or no sequence are:
- Not adding template or primer
- Adding too much primer
- Poor quality template
If you have questions about your data please do not hesitate to contact the core.
