A hybridoma capable of producing a monoclonal antibody against dectin-1, and a monoclonal antibody which specifically reacts with dectin-1. In a load circuit for subjecting an electronic switch T1 provided between a DC power supply VB and a motor M1 to the PWM control to thereby drive the motor M1, a MOSFET is provided in parallel to the motor M1. The systems may comprise one or more of a mapping and navigation system, an ablation system, and an EP recording system. Responsive to the recipient selecting the voice conference identifier, a voice conference call between selected ones of the identified conference call nodes can be established. The needle head of the present is eccentrically dispose to conform completely to ergonomics, enabling the angle of blood sampling to be lowered to make blood sampling more convenient, and the conventional products can still be used in the invention such as the needle head and the vacuum tube to avoid extra molding expense.
