EcoFlex MoClo Extension, Volume I
(Kit # 1000000253 )

Depositing Lab:   Mikhail Shapiro

The EcoFlex MoClo system is a collection of plasmid parts that can be easily combined to form new plasmids with functional expression units (and multi-gene expression systems) using Golden Gate assembly with BsaI and BsmBI. While MoClo is used across a variety of systems and organisms, this kit contains parts designed for E. coli expression.

This kit contains 96 plasmids to quickly and efficiently build a wide variety of gene expression constructs using the EcoFlex-standard MoClo system. This kit can be used as a stand-alone product, but is intended to be used with the EcoFlex MoClo Kit from the Paul Freemont Lab, which contains a number of useful parts not included in this kit.

This kit will be sent as bacterial glycerol stocks in 96-well plate format.

Description

EcoFlex MoClo Extension, Volume I extends the EcoFlex kit by adding 11 chemically inducible promoters of varying strengths, 16 ribosome-binding sites (RBSs) of varying strengths, 8 tag-compatible RBSs of varying strengths, 2 N-terminal secretion tags, 6 CDSs, 9 strong terminators, 34 backbones with ORIs of varying copy number, 6 destination vectors for cloning additional parts, and 4 nonfunctional “dummy” parts that are intended for use in certain multi-transcription unit (TU) assemblies. These parts are cross-compatible with parts from the original EcoFlex kit.

There are 10 types of vectors used for parts:
  • The backbones used for assemply (100 µg/mL kanamycin, NEB Stable):
    • pTU1-A will hold 1 TU, assembled using BsaI from Level 0 parts.
    • pTU2-a will hold 2 TUs, assembled using BsmBI from Level 1 plasmids.
    • pTU2-b will hold 3 TUs, assembled using BsmBI from Level 1 plasmids.
  • The pBP vectors (25 µg/mL chloramphenicol, NEB Stable):
    • pBP-P (holds Level 0 promoter parts; overhangs CTAT and GTAC)
    • pBP-R (holds Level 0 RBS parts that cannot be assembled with N-terminal tag parts; overhangs GTAC and CATA)
    • pBP-TagR (holds Level 0 RBS parts that must be assembled with N-terminal tag parts; overhangs GTAC and TAAA)
    • pBP-Tag (holds Level 0 N-terminal tag parts; overhangs TAAA and CATA)
    • pBP-C (holds Level 0 CDS parts; overhangs CATA and TCGA)
    • pBP-T (holds Level 0 terminator parts; overhangs TCGA and TGTT)
  • The entry vectors for making your own parts (100 µg/mL kanamycin and 25 µg/mL Zeocin®, DH10B-M.Osp807II):
    • pMetBP
    • The nomenclature is the same as above, with the addition that “RC” is a combined RBS-CDS part (overhangs GTAC and TCGA) used when the RBS is contained in the CDS part rather than a separate RBS part. These entry vectors are based on the MetClo system, and must be propagated in the DH10B-M.Osp807II strain. To create a new part, perform a BsaI assembly with the pMetBP vector and a dsDNA part fragment (usually a PCR product or duplex oligo) flanked by the appropriate overhangs.

In cases where a promoter requires a repressor or activator for induction, that protein is included in the promoter part, rather than in the backbone part. “Dummy” parts are random sequences without any activity flanked by the 4-bp overhangs corresponding to that part type, and are intended for use in assemblies where a part of that type is not desired for the function of the assembled construct but is needed for the assembly to correctly circularize (e.g., a negative control plasmid where no promoter is driving the gene of interest, or a multi-TU construct without a promoter and terminator between the TUs).

Two types of Level 1 assemblies can be performed in the base EcoFlex system. These always include a backbone, promoter, RBS, CDS, and terminator, and may include an N-terminal tag (in which case a TagR part must be used instead of an R part). If you don’t want to include one of these parts, you must use the “dummy” version of that part for the assembly to work. Level 1 assemblies are always performed using BsaI. During successful Level 1 assemblies, the dropout chromophore (amilCP or cRed) is lost and replaced with the desired TU. After transforming the assembly, only pick colonies that do not produce a blue or orange color. For additional information on these and other types of assemblies, consult the EcoFlex User Guide (DOCX, 50 KB) .

Two Level 1 assembly diagrams are shown, one with the optional N-Terminal Tag and one without. These contain the CTAT overhang, promoter, GTAC overhang, RBS, the optional TAAA and N-Terminal Tag, CATA overhang, CDS, TCGA overhang, Terminator, and TGTT overhang.

Figure 1. The two types of Level 1 assemblies that can be performed using the EcoFlex system. Note that the type of RBS part used differs between the two types of assemblies.
