Assignment Project in Chemical Biology, TFKE39
You have been given the task of isolating any of these 10 DNA sequences coding for a
protein. The gene isolated from a cDNA library and cloned into an expression vector for
expressing the protein in E. coli.
Your task will be to make a laboratory protocols in which you describe:

Which protein does the DNA sequence codes for?

Indicate how you came to this conclusion, which database did you use?

Designing primers for amplification of the gene with the help of PCR
Designing primers to amplify the gene based on a cDNA library, note 5 'or 3' end and the
forward and reverse primers. Specify how it binds to DNA (eg mark with italics or bold)
Justify your choice of primer construction and how you chose the PCR cycle to amplify
the gene.

Isolation of PCR fragments

Specify how you purify the PCR fragment after amplification.

Choice of vectors for expression in E. coli
Justify your choice of vector, based on the information you received about the protein's
properties (eg, large or small protein?, Membrane protein or cytosolic? Post
translationally modified?)

Strategy for cloning the gene into the selected vector
How should the gene be cloned into the selected vector? Which restriction enzymes
should be used? How should the gene be expressed? Under what conditions should it be
done (culture temperature, antibiotic resistance, induction, with what?

The chance that the protein is able to express in E. coli
Based on the properties of the protein (eg, large or small protein?, Membrane protein or
cytosolic? Post translational modified?) Speculate on the chance that your design will be
possible to express in E. coli

Describe methods how to characterize the protein
Based on the protein function make suggestions about how to characterize the protein (eg,
the protein enzyme activity? Is it possible to measure the protein stability with a
spectroscopic method?
The assignment will be sent to [email protected] at latest Wednesday 26th of october.
NOTE: Submitted report should be in PDF format
Late assignments without justification will not be read.
