This list is a sample of the test methods available. [7] Note that the IP designation still exists in the specification of these test methods. IP 2: Petroleum products and hydrocarbon solvents - Determination of aniline point and mixed aniline point; IP 4: Petroleum products - Determination of ash (ISO 6245:2001)
Immunoprecipitation (IP) is the technique of precipitating a protein antigen out of solution using an antibody that specifically binds to that particular protein. This process can be used to isolate and concentrate a particular protein from a sample containing many thousands of different proteins.
Other methods of sample introduction are also utilized. Electrothermal vaporization (ETV) and in torch vaporization (ITV) use hot surfaces (graphite or metal, generally) to vaporize samples for introduction. These can use very small amounts of liquids, solids, or slurries. Other methods like vapor generation are also known.
System suitability – A test run each time an analysis is performed to ensure the test method is acceptable and is performing as written. This type of check is often run in a QC Lab. Usually, system suitability is performed by analyzing a standard material (House standard or reference standard) before the unknowns are run in an analytical method.
IP codes IP65 touchscreen display IP65 LED lamp. The IP code or ingress protection code indicates how well a device is protected against water and dust. It is defined by the International Electrotechnical Commission (IEC) under the international standard IEC 60529 [1] which classifies and provides a guideline to the degree of protection provided by mechanical casings and electrical enclosures ...
Induced polarization is a geophysical method used extensively in mineral exploration and mining operations. Resistivity and IP methods are often applied on the ground surface using multiple four-electrode sites. In an IP survey (and when making resistivity measurements), capacitive properties of the subsurface materials are determined as well.
Overall ChIP-seq has risen to be a very efficient method for determining these factors, but there is a rivaling method known as ChIP-on-chip. ChIP-on-chip, also known as ChIP-chip, is an experimental technique used to isolate and identify genomic sites occupied by specific DNA-binding proteins in living cells. ChIP-on-chip is a relatively newer ...
The methods in this section are primarily computational although they typically require data generated by wet lab experiments. Protein–protein docking , the prediction of protein–protein interactions based only on the three-dimensional protein structures from X-ray diffraction of protein crystals might not be satisfactory.
