Sigma-Aldrich Corp. is set to acquire Cell Marque Corp., a California-based company, in hopes of strengthening its antibody business. Terms of the deal were not disclosed.

Cell Marque designs and manufactures antibody reagents and kits. St. Louis-based Sigma-Aldrich hopes the acquisition will strengthen its immunohistochemistry portfolio.

“We expect that Cell Marque’s strong in vitro diagnostic (IVD) antibody product lines and solid relationships with pathologists and companies that provide automated staining instrumentation will broaden the diagnostic health reach of Sigma-Aldrich,” Sigma-Aldrich President Rakesh Sachdev said.

Sigma-Aldrich announced last month it was being purchased by German pharmaceutical company Merck KGaA.
