International Classification:

B01L 3/02
B23P 11/00

US Classification:

422509, 29428

Abstract:

An automated liquid handling system is disclosed. A system includes a first pipetting group, which includes at least one pipettor, movably arranged on a first arm; and a second pipetting group, which includes at least one pipettor, movably arranged on a second arm, wherein the first arm and the second arm are movably arranged on at least one track such that the first arm and the second arm can independently move along the at least one track while keeping the first arm parallel with the second arm, wherein the at least one pipettor of the first pipetting group is arranged on a side of the first arm facing the second pipetting group, wherein the at least one pipettor of the second pipetting group is arranged on a side of the second arm facing the first pipetting group.

Abstract:

Karnal bunt of wheat is caused by Tilletia indica Mitra. Recently, teliospores morphologically resembling T. indica were isolated from bunted ryegrass seeds and wheat seed washes. Previously developed PCR assays failed to differentiate T. indica from the newly discovered ryegrass pathogen, T. walkeri. The nucleotide sequence of a 2. 3-kb region of mitochondrial DNA, previously amplified by PCR only from T. indica, was determined for three isolates of T. indica and for three isolates of T. walkeri. There was greater than 99% identity within either the T. indica group or the T. walkeri group of isolates, whereas there was approximately 3% divergence between isolates of these two Tilletia species. Five sets of PCR primers were made specific to T. indica, and three sets were designed specifically for T.

International Classification:

B01F 11/00

Abstract:

Samples in an array of containers are processed by mounting the containers on a sample stage, moving magnets into proximity with bottoms of the containers of a first column of containers to apply a magnetic field, moving the magnets into proximity with bottoms of the containers of a second column, and moving heater elements into proximity with the container bottoms of the first column. While the magnetic field is applied to the containers of the second column, heat energy may be applied to the containers of the first column. The process may be repeated for additional columns. The containers may also be shaken to agitate the samples. A single apparatus may perform heating, shaking, and magnetic field application, without needing to transport the containers to different stations.
