Applications of BBa_K2353001

When fully assembled, p-lambda-r LacI transcribes tsPurple and LacI represses pLac, preventing transcription of ClpXP-CI. Upon induction with IPTG, LacI binds to IPTG which prevents repression of pLac. Therefore, ClpXP-CI is transcribed; ClpXP should recognize the DAS deg tag and degrade the tsPurple protein. The ensuing levels of expression could then be compared to that of BBa_K2353000 (tsPurple without a deg tag) to see the relative level of degradation experienced.

tsPurpleDAS was ordered and hydrated from IDT and then digested and ligated into 1C3 so that it could be sent for sequencing and then submitted. Running the digest on a gel showed tsPurpleDAS to be the correct length, however when sequenced, we discovered that the DAS degradation tag was not present. It is hypothesized that at some point during the cloning workflow, tsPurple was confused with tsPurpleDAS.

Gel results from a digest of all three tsPurple parts. From top to bottom: BBa_K2353000, BBa_K2353002, BBa_K2353001

Using Eurofins for sequencing, we realized that our tsPurpleDAS sequence was missing DAS deg tag. The results are shown below as our tsPurpleDAS construct aligned with the tsPurpleDAS sequencing results.
