Invitrogen Dominates Cell Culture Market

Revealed in New Life Science Dashboard™ from Percepta Associates

However Invitrogen Challenged by HyClone and Sigma in Specific Cell Culture Market Segments

Carlsbad, Calif. -- March 07, 2007 – Today Percepta Associates launched its Cell Culture Life
Science Dashboard™ market research report revealing Invitrogen (NASDAQ:IVGN) as the dominant
supplier in the cell culture research market, which includes: basal media, animal sera, balanced salt
solutions, serum free media, dry powdered media and growth and attachment factors. The Cell
Culture Dashboard shows Invitrogen to be the leading cell culture supplier in all six market
segments surveyed. However, Invitrogen is challenged by close competitors Thermo Fisher
Scientific/HyClone (NYSE:TMO) which takes the lead in supplying North American animal sera and
Sigma (NASDAQ:SIAL), the leading supplier of growth and attachment factors to the academic
market. Opportunities for companies looking to gain share in the cell culture market lie in dashboard
findings that four of the six market segments surveyed showed greater than 20% of scientists using
cell culture techniques are considering switching to a different supplier.

This new cell culture market report from Percepta Associates, a market research and strategic
consulting firm focused on serving life science companies, was developed from responses to a 35-
question survey by over 350 scientists predominantly located in North America and Europe.
“It’s vitally important for cell culture suppliers to have a clear picture of where opportunities lie in
this large, mature and crowded market” said Mike Klein, Principal of Percepta. “This dashboard will
help companies identify the most attractive areas for winning market share from leading suppliers,
like Invitrogen, as they plan sales and marketing strategies”
