RANDOM SEQUENCE FOUND WITHIN PART

CGCTGATAGTGCTAGTGTAGATCGC is found after the RFP stop codon and before the BioBricks suffix. Should not affect transcription or translation of RFP, but good to keep note of it especially in analyzing sequencing results. (KP of siGEM)

• Please note that the above sequence is the old "barcode" sequence added to all of the original CDSs in the early BioBrick part collections. I.e., it's not a random sequence. See https://parts.igem.org/cgi/htdocs/barcodes.cgi for more information (D. Endy).
  • FURTHER NOTE The Registry is not displaying barcodes on any of the original parts. The presented sequence information is wrong. This is a serious bug in the Registry that need to be fixed (D. Endy). Drew 14:34, 1 November 2010 (UTC)

Characterization of the Photostability of mRFP1 Photobleaching curve of mRFP1 with a HBO100 mercury-arc lamp" XL10 Ultracompetent cells were transformed with BBa_E1010 with BBa_R0010 as the wild-type lac promoter and induced overnight with IPTG.The overnight was bleached for 180 minutes with HBO100 (100W Mercury-arc lamp). Fluorescence data was taken using a Tecan Safire II with the parameters shown in Table 3. Fluorescence values are shown in Table 4.

Figure 1. E.coli strain MG1655 expressing BBa_E1010 under control of BBa_K907005 after overnight culture. 3mL culture with M9 media in 14ml round bottom tube(left), and centrifuged cells in eppendorf tube(right). The expression of BBa_1010 is clearly observed with naked eye after overnight culture. We recommend you to measure the emission wavelenth at 619nm. Because the maximum excitaion and emission wavelenth are too close to each other, the signal overflows. You can get more precise results with our recommendations. BBa_E1010 was successfully used to produce mRFP in E.coli strain MG1655 in LB or M9 minimal media under the control of promoter-BBa_J23119 and RBS-BBa_B0034 in the Dual Phase Protein Generator(mRFP default), BBa_K907005

Characterization of RFP BBa_E1010 We have characterized RFP BBa_E1010 in two different chassis to test the compatibility and the possible range of expressions before limitations in the cell metabolism. Method We have made constructs with a synthetic promoter library (SPL) in front of the E1010, by using BBa_I13507 and the plasmid backbone pSB3T5. For information on design of an SPL compatible with the BB standard see [http://bbf.openwetware.org/RFC.html#BBF_RFC_63:_DTU_Synthetic_Promoter_Library_Standard BBF RFC63]. We have benchmarked the relative promoter strength range achieved from the SPL to the standard promoter BBa_J23101, by calculating the relative promoter strength in vivo as suggested in [http://bbf.openwetware.org/RFC.html#BBF_RFC_19:_Measuring_the_Activity_of_BioBrick.E2.84.A2_Promoters_Using_an_In_Vivo_Reference_Standard BBF RFC 19]. For further explanation on methods see our [http://2010.igem.org/Team:DTU-Denmark iGEM_DTU_2010 wiki]. Results We show that the RFP E1010 can be expressed with the following results In XL1blue with an RPU range form 0 to at least 1,13 RPU. In DHA5&alpha with an RPU range from 0 to 1,35 RPU. Graph2 XL1BLUE illustrates the variation in promoter strengths of the SPL mapped against the reference promoters. PM corresponds to BBa_J23101, PS corresponds to BBa_J23100 and PW corresponds to BBa_J23116. Graph3 XL1BLUEillustrates the specific activities of the SPL promoters ranked together with the reference promoters. Graph4 DH5aillustrates the variation in promoter strengths of the SPL mapped against the reference promoters. PM corresponds to BBa_J23101, PS corresponds to BBa_J23100 and PW corresponds to BBa_J23116. Graph5 DH5a illustrates the specific activities of the SPL promoters ranked against the reference promoters.

Antiquity

This review comes from the old result system and indicates that this part did not work in some test.

Nkessler

We successfully used this part for a read out system, e.g. in BBa_K389016. Additionally we compared it with a luciferase: BBa_K389004.
