Part:BBa_K528017

Expression Adapter s02_20k

This part encodes expression adaptor designed to have strength 28,57% relative to B0034 and uniform expression level regardless of attached protein.

Clonning:

The lab work was supervised by:

The part is in RFC25 standard. It consists of BBa_J23100 promoter followed by BBa_B0034 RBS, 5 nucleotide spacer and short peptide.

Spacer and peptide were designed using in silico evolution to provide uniform expression level regardless of following protein coding sequence.

Summary of design algorithm:

Using RBSCalculator program we have determined that this part expression strength is 28,57% relative to BBa_B0034

All our measurement results are summarized in the table below:

Part Name	Description	Expression level in thousands of absolute RBSDesigner units	Expression level as %B0034+YFP
BBa_K528015	Expression Adapters s00_45k	45	64,29%
BBa_K528016	Expression Adapters s01_24k	24	34,29%
BBa_K528017	expression adapters s02_20k	20	28,57%
BBa_K528018	Expression Adapters s06_16k	16	22,86%
