Part:BBa_K864444

RFP-Linker-SYFP2

This part is a component of the Uppsala University iGEM 2012 modular small RNA screening system, together with the spott42 sRNA BBa_K864440. It can also be used for studing up- or downregulation of genes by other mechanisms.

Use this system to screen for downregulation of your gene by a random small RNA library. PCR amplify your 5’UTR, adding XbaI and EcoRI sites upstream and a BamHI site downstream, and clone into any backbone carrying this part, replacing the RFP cassette. By cloning with EcoRI and BamHI, the cloning will function as a red/white screening system. You have now created a novel BioBrick, that can be used to screen for translational downregulation of your gene of interest.

SYFP2 BBa_K864100 is situated downstream of the RFP cassette BBa_J04450 and is connected in frame with a 10 aa glycine-serine repeated linker BBa_J18922, to prevent folding errors in the SYFP2. Before the linker there is a BamHI restriction site (GGATCC), which translates into glycine-serine in E coli.

When screening for working small RNAs, it's recommended to include the first 15 codons of your gene of interest.
