Template:FAQ/Quality Control

Where can I find the quality control information for a part sample?

The quality control information for a part sample is summarized on its Get This Part page. We recommend also taking a close look at the sequence results before using a part. You can do view the sample analysis page by clicking on the More... link next to a sample's sequence result.

Please see Quality Control for more information.

Do all part samples in the Registry have quality control information

The Registry does not have QC information for all of its part samples (particularly samples submitted before 2010). However since 2010, we have sequenced part submissions sent in pSB1C3.

Part's with an available sample that has been sequence confirmed or ends confirmed, will say:

• Sample in Stock

You can see a summarized version of QC information on a part's Get This Part page.

How does the Registry sequence parts?

Parts are sequenced using the VF2(BBa_G00100) and VR (BBa_G00101) sites on the pSB1C3 (and other pSB_) plasmid backbone. Generally, parts that are under 1600bp are fully sequence confirmed.

However, long parts are not fully confirmed, and currently, the Registry does not do internal sequencing for these parts.

Are Confirmed parts guaranteed to work?

iGEM HQ cannot make any qualitative statements on if a part functions as described. For functional characterization, we recommend taking a look at a part's main page and experience page for information on how the part works.

Furthermore, we recommend that users sequence a part sample themselves before using it.

What does a sequence result of "Long Part" mean?

The Registry currently uses Sanger sequencing for quality control, and uses the VF2 and VR primer sites on pSB1C3, to sequence into the part. These reads are generally 600-1000bp long, and as such, we usually do not have full coverage for parts greater than 1600bp.
