A fluid delivery system includes a laboratory instrument that operates using fluid retained in one or more containers. Also provided herein are vectors and host cells comprising those nucleic acid sequences, chimeric polypeptide molecules comprising the polypeptides of the present invention fused to heterologous polypeptide sequences, antibodies which bind to the polypeptides of the present invention and to methods for producing the polypeptides of the present invention. A source region in the substrate is adjacent to but laterally spaced from the first side of the conductive gate and the first spacer, and a drain region in the substrate is adjacent to but laterally spaced apart from the second side of the conductive gate and the second spacer. A sliding device allows the external coil to be positioned along a second direction.
