MADISON, Wis.--(BUSINESS WIRE)--Promega Corporation in conjunction with Kazusa DNA Research Institute (KDRI) in Chiba Prefecture, Japan will soon offer vectors encoding Promega HaloTag™ with genetic content from KDRI’s catalog. The KDRI content derives from large, typically difficult to clone human genes. In addition, there will be a comprehensive catalog of human transcription factors commonly used in research and drug discovery. As a result, researchers can gain ready access to the multi-functional HaloTag fused to these larger proteins.
