Biacore Interim Report January - March 2005

UPPSALA, Sweden, April 28, 2005 (PRIMEZONE) --

 -- Biacore's first quarter sales showed strong recovery
    increasing by 22% to SEK 116.0 million (95.4). Sales in
    Asia-Pacific grew by 236% due to the continuing recovery
    in the important Japanese market and increased demand
    from emerging markets such as China. The growth in
    Asia-Pacific more than offset lower sales in Europe
    and the Americas. Excluding the effect of exchange rates,
    total sales increased by 26%.

 -- Operating income for the first quarter rebounded strongly
    to SEK 13.9 million (-1.4) due to the much improved sales
    figure and lower R&D spending.

 -- Net income for the first quarter amounted to SEK 12.0 million
    (-1.0). Diluted earnings per share were SEK 1.24 (-0.08).

 -- Biacore extended its leading global position in the field
    of protein interaction analysis with the launch of
    Biacore(R)T100 in February. The market reception to this
    new system has been very positive.

 -- Biacore's product line was extended further in March with
    the acquisition of FLEXChip System and technology from
    HTS BioSystems Inc. This acquisition is in line with Biacore's
    strategy of looking for complementary external growth

 -- In February, Biacore appointed Mr. Terry Pizzie as
    Senior Vice President of Commercial Operations.

 -- Biacore maintains its previous outlook for the full-year
    2005: Biacore anticipates achieving an increase in sales

    with variations between the quarters.
