Abstract: An anti-rotation apparatus for a pipe joint includes: a stop piece having a body with a retaining portion and a locking part; a first joint part and a second joint part coupled to one another and having an axis in a lengthwise direction of the pipe joint; a locking receptacle provided in the first joint part; and a receiving receptacle provided in the second joint part. The retaining portion of the body of the stop piece is retained in the receiving receptacle of the second joint part and the locking part protrudes in a direction of the locking receptacle. When the locking part and the locking receptacle are rotationally aligned and the locking part is disposed in the locking receptacle of the first joint part, relative rotation about the axis between the first joint part and the second joint part is prevented.

Abstract: The present invention relates, in general, to a method of expressing the outer membrane protein P2 from Haemophilus influenzae type b (Hib-P2) and fusion proteins thereof. In particular, the present invention relates to a method of expressing the outer membrane protein P2 from Haemophilus influenzae type b or fusion protein thereof in E. coli wherein the Hib-P2 protein or fusion protein comprises more than 2% of the total protein expressed in E. coli. The invention also relates to a method of purification and refolding of Hib-P2 protein and fusion protein thereof.
