Stop Generation System™ Kit (STOP™ Kit)

The transposon based STOP™ Kit for generating truncated proteins for functional assays: saturated libraries of mutated proteins in a single reaction

Description

Transposon-based STOP Kit is developed for functional analysis of proteins. This new transposon tools enable the creation of saturated libraries of mutated proteins in a single reaction. The STOP Kit Entranceposons contain translational stop codons in all three reading frames within the terminal portion of the transposon sequence. The proprietary modification of the Stop Generation System™ Kit makes it possible to generate a saturated C-terminal deletion library from virtually any target protein with a maximum addition of three amino acids. The transposon-based method requires less hands-on time than any other method, thousands of mutated clones are ready for expression studies in just two days.

Applications

The STOP Kit generates truncated proteins for functional assays of:

Transposition reaction into linear target DNA

Storage stability

Store the components at –20 °C. Stable for 1 year from the date of packaging when stored and handled properly.

System protocol

Day 1. Perform the transposition reaction, in which MuA Transposase catalyzes the in vitro transposition reaction by inserting the Entranceposons into the target DNA plasmids at random sites (70 min). Transform the DNA into competent E.coli cells with the transposition reaction mixture. Plate out on selection plates (LB+kanamycin) and cultivate the cells overnight.

Time required: appr. 3 h
Hands-on time: max. 1 h

Figure 2. In vitro transposition reaction. (Incubate 60 min at 30 °C, Heat inactivate 10 min at 75 °C)

Day 2. Pool the colonies from transformation plates and prepare plasmid DNA from the pool. Transform the expression host cells with the plasmid pool.

Time required: appr. 3 h
Hands-on time: appr. 2 h

 

Result: library of truncated proteins ready for expression studies.
