Label	Id	Description
flow probe	OBI_0000519	[An NMR probe that allows the automatized flow-through of a sample. The sample is aspirated via a syringe pump into the Flow probe, the NMR spectrum is acquired and when the experiment is complete, the sample is returned to back to an external source (well plate) or flushed to waste. Sometimes pulsed field gradients (PFG) can be established in flow probes.]
NMR magnet	OBI_0000517	[A magnet which induces a certain frequency (MHz) and which has a certain bore diameter.n alt The NMR signal is a natural physical property of the certain atomic nuclei but it can only be detected with an external magnetic field. A magnet is a fundamental part of an NMR instrument which induces an electromagnetic force field (RF pulse) and by this excites and aligns the spins of the electrons of the NMR acquisition nucleus. It is usually a big (superconducting) electromagnet which is cooled by liquid helium and can be adjusted to a frequency between 200 and 950 MHz. The magnetic field strength is measured in Tesla or Gauss.]
chromatofocusing column	OBI_0000515	[A chromatofocusing column is a chromatography column in which a resin is equilibrated at one pH and eluted at a second pH. The use of a weak ion-exchange resin causes a pH gradient to be formed at the solvent front owing to the buffering action of the resin. This pH gradient in turn leads to an ordering of proteins by isoelectric point. Molecules of charge sign opposite the resin bind; those of charge sign like the resin do not bind.]
ELISPOT assay measuring epitope specific interleukin-15 production by T cells	OBI_0001846	[An assay of epitope specific interleukin-15 production by T cells that uses an ELISPOT assay.]
chromatin interaction analysis by paired-end tag sequencing assay	OBI_0001848	[An assay that incorporates chromatin immunoprecipitation (ChIP)-based enrichment, chromatin proximity ligation, Paired-End Tags, and high-throughput sequencing to determine de novo long-range chromatin interactions genome-wide.]
nuclear ligation assay	OBI_0002438	[An assay that detects the proximity of chromosomal DNA through the use of a ligation reaction in isolated nuclei.]
chromosome conformation capture assay	OBI_0002439	[A nuclear ligation assay that detects chromosomal interactions between any two genomic loci. Chromatin segments are cross-linked, cut by restriction enzymes, ligated, and finally analyzed by PCR.]
chromosome conformation identification objective	OBI_0001917	[A molecular feature identification objective that aims to determine spatial organization of chromatin.]
structural analysis by paired-end tag sequencing assay	OBI_0001849	[An assay that incorporates Paired-End Tags and sequencing technology to determine structural variants.]
brain	UBERON_0000955	[The brain is the center of the nervous system in all vertebrate, and most invertebrate, animals. Some primitive animals such as jellyfish and starfish have a decentralized nervous system without a brain, while sponges lack any nervous system at all. In vertebrates, the brain is located in the head, protected by the skull and close to the primary sensory apparatus of vision, hearing, balance, taste, and smell[WP].]
transcript analysis by paired-end tag sequencing assay	OBI_0001850	[A transcription profiling assay that determines transcripts, gene structures, and gene expressions using Paired-End Tags and sequencing technology.]
paired-end library preparation	OBI_0001852	[A library preparation that results in the creation of a library of the 5' and 3' ends of DNA or cDNA fragments using adaptors and endonucleases. The preparation may or may not include cloning process. ]
RNA sequencing assay	OBI_0001177	[An assay that determines the sequence of an RNA molecule.]
transcription start site identification objective	OBI_0001851	[A transcription profiling identification objective that aims to characterize the transcription start sites of genes.]
DNase I hypersensitive sites sequencing assay	OBI_0001853	[An assay that identifies the location of regulatory regions, based on the genome-wide sequencing of regions super sensitive to cleavage by DNase I.]
protein and RNA interaction identification objective	OBI_0001854	[A sequence feature identification objective that aims to characterize the interactions between protein and RNA.]
cerebral cortex	UBERON_0000956	[The thin layer of gray matter on the surface of the cerebral hemisphere that develops from the telencephalon. It consists of the neocortex (6 layered cortex or isocortex), the hippocampal formation and the olfactory cortex.]
splitless GC injector	OBI_0000525	[Injected sample enters column immediately (while split valve to split vent is closed). Here a sample is introduced into a heated small chamber via a syringe through a septum - the heat facilitates volatilization of the sample and sample matrix. The carrier gas then either sweeps the entirety (splitless mode) or a portion (split mode) of the sample into the column. In split mode, a part of the sample/carrier gas mixture in the injection chamber is exhausted through the split vent.]
Varian VXR spectrometer	OBI_0000524	[A Varian NMR spectrometer.]
magic angle spinning rotor	OBI_0000523	[A rotor device that holds the NMR sample and enables the adjustment of the orientation of the rotation axis for a sample in a NMR instrument in the magic angle.]
