Abstract: Provided are an optical spectrum analyzer and a pulse-modulated light measurement method capable of measuring pulse-modulated light even when a pulse-on time and a pulse period of the pulse-modulated light are unknown. Pulse-modulated light (DUT) is incident on a diffraction grating 3. A first light receiving unit 8 receives the 0th-order light of diffracted light diffracted by the diffraction grating 3. A second light receiving unit 7 receives diffracted light of an order other than the 0th-order light. A measurement timing signal generation unit 9 generates a sampling signal based on the 0th-order light received by the first light receiving unit. The spectrum of the diffracted light received by the second light receiving unit is measured based on the sampling signal generated by the measurement timing signal generation unit.

Abstract: The present application provides the medicaments comprising the antibodies binding to phospholipase D4 (PLD4) as well as a method using said medicaments for detecting and suppressing activated B cells. The present application is further directed to therapy of auto-immune diseases and allergosis, resulting from the active-repressing function. In order to solves these problems, the present application provides that a monoclonal antibody binding to the extracellular domain of phospholipase D4 (PLD4) protein, or a fragment containing an antigen-binding region thereof as an active ingredient.
