Agilent Technologies, or Agilent, is an American company that designs and manufactures measurement instruments and equipment for life science, medical diagnostics, and chemistry applications.Agilent's predecessor company was Hewlett-Packard , founded in 1939 to make electronic test equipment. In 1999, HP spun-off their test and measurement division as Agilent. The resulting IPO of Agilent stock may have been the largest in the history of Silicon Valley at the time. In 2014, Agilent spun-off its electronics instruments division into Keysight Technologies.Agilent maintains a central research and development group, Agilent Laboratories, that conducts the company's research in such areas as microelectromechanical systems, nanotechnology, and life science. This centralized group is based on the original Hewlett-Packard Lab's design and was formed by dividing the original HP Labs group into two when Agilent was carved out of HP in 1999. Wikipedia.

A method for sequencing a nucleic acid is provided. In certain embodiments the method comprises obtaining a duplex comprising a nucleic acid and a primer, wherein the primer has a nuclease resistant 3 end, combining the duplex with a chain terminator nucleotide and a proof-reading polymerase to produce a reaction in which the polymerase idles on the added chain terminator nucleotide, identifying the chain terminator nucleotide added to the end of the primer; and adding a nuclease-resistant nucleotide to the end of the primer after the polymerase has idled on and removed the added chain terminator nucleotide, thereby producing a duplex comprising the template and an extended primer that has a nuclease resistant 3 end.

Methods of analyte derivatization and soft ionization are provided. The methods include contacting a sample including an analyte with a derivatization agent to produce a modified analyte including a pseudo-molecular analyte group and a leaving group connected via a fragmentable bond; and selectively breaking the fragmentable bond under soft ionization conditions to produce a predominant first fragmentation product including the pseudo-molecular analyte group and a second fragmentation product including the leaving group. The method may further include analyzing the first and second fragmentation products in a mass spectrometer to identify an ion corresponding to the pseudo-molecular analyte group. Also provided are methods for detecting analytes using gas chromatography-mass spectroscopy (GC-MS). These methods find use in a variety of applications in which mass spectroscopic analysis of samples is desired.

The present invention relates to guide RNAs comprising adaptor segments having one or more modifications, and their use in homologous recombination by CRISPR:Cas systems. The modified adaptor segments are resistant to degradation by RNaseH. The present invention also relates to a dual guide RNA strategy in which a first guide RNA directs a Cas enzyme to make a double-strand break at a first target sequence, and a second guide RNA comprises an adaptor segment attached to a donor polynucleotide, and binds a second target sequence that is offset from the first target sequence.

The present invention provides a simple and rapid method for preparing purified transposase complexes that are highly suited for fragmenting DNA. The method includes forming transposase complexes with oligonucleotide adapters in cell lysate, then purifying the complexes from the other substance in the cell lysate. Purification is accomplished using a specific binding pair, in which one member of the pair is bound to an oligonucleotide adapter of the complex and the other member of the pair is bound to a solid substrate. The bound complexes can be immediately used in DNA fragmentation reactions to produce solid substrate-bound DNA fragments, which can be used for any number of purposes, including as templates for amplification and sequencing.

A light source (11, 30, 40) having first and second wire-grid polarizers (63, 64) and a laser (31, 71) that emits a beam of linearly polarized light that is characterized by a propagation direction is disclosed. The first wire-grid polarization filter (63) is characterized by a first linear polarization pass direction and a first actuator (65) for causing the first linear polarization pass direction to rotate relative to the beam of linearly polarized light. The second wire-grid polarization filter (64) is characterized by a second linear polarization pass direction and a second actuator for causing the second linear polarization pass direction to rotate relative to the beam of linearly polarized light. A controller (29) sets the first and second linear polarization pass directions to provide linearly polarized light having a specified polarization direction.

A method and apparatus for obtaining reference samples, i.e. measuring reference targets (62) on a reference stage (61) during the generation of a mid-infrared (MIR) image without requiring that a sample specimen (16), being placed on a specimen stage (57) and imaged, be removed is disclosed. A tunable MIR laser (11) generates a light beam (18) that is focused onto the sample specimen on the specimen stage that moves the specimen in a first direction (33). An optical assembly includes a scanning assembly (31) having a focusing lens (55) and a mirror (56) that moves in a second direction (32), different from the first direction, relative to the specimen stage. A light detector (13) measures an intensity of light leaving the point on the specimen. A controller (39) forms an image from the measured intensity. The reference stage (61) is positioned such that the scanning assembly moves over the reference stage in response to a command so that the controller can also make a reference measurement.
