Label	Id	Description
secondary cultured cell	OBI_0001866	[A cultured cell that has been passaged or derives from a cell that has been passaged in culture. ]
cultured cell	CL_0000010	[A cell in vitro that is or has been maintained or propagated as part of a cell culture.]
primary cultured cell	CL_0000001	[A cultured cell that is freshly isolated from a organismal source, or derives in culture from such a cell prior to the culture being passaged.]
establishing cell line	OBI_0001867	[a process whereby a new type of cell line is created, either through passaging of a primary cell culture to relative genetic stability and compositional homogeneity, or through some experimental modification of an existing cell line to produce a new line with novel characteristics (e.g. immortalization or some other stable genetic modification, or selection of some defined subset).]
cell line	CLO_0000031	[A cultured cell population that represents a genetically stable and homogenous population of cultured cells that shares a common propagation history (i.e. has been successively passaged together in culture). ]
fraction collector	OBI_0000536	[A fraction detector is a device that allows regular or specified samples to be taken from a column eluate and stored in a retrievable form. The storage vessels are usually small sample tubes or vials that are oriented in a rotating disk or in a moving belt, there movement usually being controlled by a microprocessor. On receiving a signal from the microprocessor, the next vial is placed under the column outlet and the eluate collected until receiving another signal from the computer. Once the properties of the chromatogram that describes the separation has been ascertained, then the collection program can be defined. The fractions can be collected on a basis of time either at regular intervals or a specific times to collect specific peaks. Alternatively the fractions can be collected by monitoring the detector output and when a peak starts to elute the fraction collector is activated and the peak collected in a specific vial. When the peak returns to base line the column eluate is then directed to waste until the next peak starts eluting. Fraction collectors are in common use with most liquid chromatographs. They are used to collect samples for further purification, subsequent examination by spectroscopic techniques or for biological or organoleptic testing.]
gel filtration column	OBI_0000535	[A Gel filtration column is a chromatography column for size-exclusion chromatography, in which the stationary phase is a gel. The main application of gel filtration chromatography is the fractionation of proteins and other water-soluble polymers.]
size exclusion column	OBI_0000618	[A size exclusion column is a chromatography column as used in size exclusion chromatography and which enables the separation of mixtures according to differrences in molecular size.]
tecmag NMR instrument	OBI_0000534	[An NMR instrument that is manufactured by tecmag.]
affinity column	OBI_0000533	[An affinity column is a chromatography column that is used in affinity chromatography. Differences in the affinity of molecules to be separated to a stationary phase are used for discriminate retention.]
column cartridge	OBI_0000532	[A device that binds the chromatography column and additional connector elements and / or valves or syringes into one physical unity for further processing.]
Bruker CryoProbe	OBI_0000531	[The Bruker BioSpin CryoProbe is a high-performance cryogenically cooled probe developed for high-resolution applications. It has improved signal/noise (S/N) ratios obtained by reducing the operating temperature of the coil and the pre-amplifier. As a result, the efficiency of the coil is improved and the noise of the coil and the pre-amplifier are reduced.The dramatic increase in the S/N ratio by a factor of 3-4, as compared to conventional probes, leads to a possible reduction in experiment time of up to 16 or a reduction in required sample concentration by a factor of up to 4. The CryoProbes possess key characteristics for NMR analysis:n Significant S/N gains (with moderately salty samples also)n Short pulse widthsn Short ring down timesn Linear behavior in power responsen Gradient capabilityn CryoProbes are available as Triple Resonance, Dual, Selective X Detection, MicroImaging, and Quad Nucleus Probes configurations at 400 MHz and highern All high resolution probes have a lock circuitn All high resolution probes have Z-gradient.]
Bruker UltraShield Plus NMR magnet	OBI_0000530	[An NMR magnet of which Brukers claims it is the latest and most advanced self-shielding NMR magnet technology ever developed. These magnets are the ultimate advancement in high performance, actively-shielded NMR solutions. They offer unprecedented shielding performance whilst ensuring no compromise in system homogeneity, stability or cryogenic specifications.]
imaging NMR probe	OBI_0000539	[An NMR probe that is designed for generating pictures from sample states via NMR imaging.]
in-line filter	OBI_0000538	[A solvent filter that sits between the pump and the injection valve that prevents dust particles, general debris and, to some extent, bacteria from entering the chromatography system. Contaminants can interfere with the low-pressure gradient former or the pump and particles entering valves may interfere with the proper function. The result could cause an increased baseline noise, non-repeatable gradient forming, unreliable flow rate or other interferences. Solvent in-line filters are low-pressure filters and will allow a high flow rate due to a large surface area and large porosity.]
chromatography detector filter	OBI_0000592	[An optical filter that is used to obtain monochromatic light of a defined wavelength from detector lamps.]
copy number variation profiling assay	OBI_0000537	[An assay that determines lost or amplified genomic regions of DNA by comparing genomic DNA originating from tissues from the same or different individuals using specific techniques such as CGH, array CGH, SNP genotyping]
genetic material	OBI_0001868	[A nucleic acid macromolecule that is part of a cell or virion and is inherited from an immediate ancestor, or incorporated in a manner that it has the disposition to be replicated and inherited by descendants.]
LSRFortessa X-20	OBI_0001871	[A flow cytometer analyzer manifactured by Becton ans Dickinson. Can be configured with up to 5 lasers, 488nm, 532 or 561 nm, 640 nm, 405 nm, 355 nm for measuring up to 20 parameters simultaneously. ]
flow cytometer analyzer	OBI_0400008	[An analyser is a flow_cytometer that is used to measure properties of particles (whole cells, nuclei, chromosomes, diatoms, plankton, bacteria, viruses) by moving these particles through a detection chamber. An analyser is used to collect data for analysis.]
