The small and wide angle neutron scattering instrument, TAIKAN, was installed on BL15 in the Materials and Life Science Experimental Facility (MLF) of J-PARC. The beam commissioning was started in January 2012, and Users program was started in March 2012. TAIKAN is designed for efficient measurement in wide-q range of 0.005-10[]. We measured three typical proteins of Myoglobin(Mb), -Lactoglobulin (LG), and Hemoglobin(Hb) in solution by using TAIKAN, in order to verify the performance of wide-q range. The internal structure of Mb and LG is Helix-rich and -sheet-rich, respectively. We will present the result of comparing measuring data with calculation profiles and the performance of TAIKAN.
