Color Balance
This snippet causes dropdowns to open on page load. This text/paragraph does not appear in the output.
Selecting index adapters with diverse sequences for pooled libraries optimizes color balance for successful sequencing and data analysis.
When index adapter sequences are recorded in Local Run Manager, Instrument Run Setup, or the BaseSpace Sequence Hub Prep tab, the software confirms that libraries in a pool have unique index combinations. However, Local Run Manager, Instrument Run Setup, and BaseSpace Sequence Hub do not check for color balance.
Example Index Adapter Combinations
The following table provides examples of good and bad index combinations, to demonstrate color balance on a four-channel system. The good examples have signals in both channels (red and green). The bad examples are missing signal in one channel, as indicated with an X.
