NEWEAST BIOSCIENCES

NewEast Biosciences are specialized in generating protein configuration-specific monoclonal antibodies that recognize active (GTP-bound) G proteins (including Ras-super-family small GTPases and heterotrimeric G proteins). These unique antibodies do not recognize the inactive (GDP-bound) G proteins. These monoclonal antibodies have been successfully used to immunoprecipitate active G proteins from cell lysates, and for immunohistochemical staining of active G proteins in cultured cells or in tissue sections. Hence, these antibodies can be used to study the spatial and temporal dynamics of cellular signaling involving big and small G proteins, the future direction of signal transduction studies.
