We are currently using XL-1 Blue to express a clones gene from rabbit sperm.
The rate of production of recombinant protein is not great at 1 ug/ml
culture and in addition we see an number of breakdown products which are
being formed in the bacteria not during purification. Other people here who
 have expressed other (unrelated) sperm proteins also see the breakdown
 problem. What other coli strains are appropriate? What ae the advantages
and disadvantages?
