Lexington firm enters Japanese market

Lexington-based Transposagen Biopharmaceuticals, which creates genetically modified laboratory rats, said Wednesday it has reached an agreement with Trans Genic Inc. to enter the Japanese market.

Trans Genic, which also deals in genetically engineered mice, will have non-exclusive rights to market Transposagen's products in Japan.

Transposagen's most well-known product is the TKO Knockout Rat, which has been genetically engineered to mimic a human disease. The company said 90 percent of the world's knockout rat lines have been created using its technology. The rats are used for drug discovery and development research.
