LONDON, May 9 (Reuters) - Biotech firm Abcam said it would not make an offer for Horizon Discovery after the company rejected its approach and said it saw little strategic rationale in a combination.
Shares in Horizon slumped 12 percent.
Abcam announced earlier this month that Horizon had rejected a 270 million pound ($366 million) approach and said it was going public with the news to try and force it into talks.
