We use this strain to express recombinant proteins for purification. It contains tRNAs for rare codons, so the expression of human protein is more efficient.
Protein expression and purification
competent cell and plasmid
The cells are very efficient, only need to use 5 uL to do transformation
I had a lot of success to express and purify high yeild of protein using this cell strain.
N/A
High yeild of protein expressed
Expensive
I would recommend using this competent cell to express and purify recombinant proteins.
